In this video we visit East Coast Gear Supply (ECGS) in Louisburg, North Carolina to show you how to regear and rebuild your Toyota 8" rear differential (3rd member). Chase Perry, the CEO of the company does all the work and explanation of the process. There is probably no better teacher or presenter of this subject matter because the guy has been building differentials for a very long time and he knows his stuff.

There was a guy that reported his pinion shaft threads got damaged by not unstaking the nut before removing it. At playtime 14:38, Chase says there's no need to unstake the nut before removing it with a 30mm socket. To play it safe so this doesn't happen to you, I would unstake the nut before removing it. This is the toolset I bought to stake and unstake nuts: amzn.to/3j9AnPD
Great video! Thanks to Timmy and Chase at ECGS for taking their valuable time to document the science & art of building a high quality differential.
We're glad you like it. We totally lucked out being able to partner with ECGS to make these videos happen. Chase was very giving of his time and did a great job explaining everything. Thanks for the comment.
East Coast Gear Supply to the rescue!
My diff was rebuilt by a local shop a year ago and I was still having issues. After your last video at ECGS I decided to bite the bullet and go with them instead for the 3rd member rebuild and regear in my '91 4x4 Pickup, and I couldn't be happier! Just installed it last weekend.
I'm 50 miles into the break-in period with the recommended Lucas gear oil and I'm already happy as a clam. The diff arrived here in Michigan packaged perfectly and was put together right to the specs I picked out. The gear pattern looked perfect, and they're running cool and quiet.
Thanks Tim and thanks East Coast Gear Supply, cheers from Michigan!
Smart choice going with ECGS. Glad you had a good experience with them. They are a great company. I'm around the same miles in on my diff break-ins. Stay tuned for the front differential regear and locker install we filmed. I got an Eaton e-locker.
@@TimmyTheToolman nice! I almost went with a locker but I’ll probably do that further down the line after the 5VZ swap (another job I owe you some beers for!) party. Eager to see how you like the Eaton, that’s what I was looking at too (with a Detroit TrueTrac up front).
@@gohilux I'll report back to the video in a pinned comment after I get to test out the locker on a wheeling trip. Good luck with the 5VZ swap.
My dad taught me much of what Chase mentions in the video. One often overlooked tip to make bearing and race installation easier is to put races in the freezer for a couple hours and to warm bearings on a hot plate, shop stove or other heat source just like he did the ring gear. As for bearing removal, I often use the destructive method of a cutoff wheel on a die grinder to deeply score the race after the cage has been removed and then split it with a cold chisel. Easy to do when you are replacing bearings anyway.
I am regearing my 92’ 4Runner currently and it will be my first Toyota diff, but I have done several 3/4 tons and a couple of 2 ton farm trucks. A clean workspace and patience is what is most needed. This video will help me a bunch.
Sounds like you had a cool dad. Thanks for sharing your tips. Good luck with the regear.
Fantastic and greatly appreciate the time that Chase Perry took with you. Also, for you (all) to make and edit this. Slick as ever and not a wasted minute.
Not many CEOs would do this and I’m sure he really enjoyed getting his hands dirty, too. While he is certainly very hands-on I’m sure he spends too long in meetings and the like. Great to get his experience and similar to something else I watched on diffs recently, great to see an arbour press used when that is what’s needed, rather than a hydraulic monster. I also liked to see the tooling, disassembly, several partial rebuilds and check processes that ensure the final thing is as good as possible. Also very interesting to learn that the use-case is significant when tailoring the rebuild process. I can see this now but had no idea.
Final (small) point is that while the choice of an E-locker is hugely relevant I would have liked to see the central ‘differential’ pinion area explored more. If only you could have worked on a G145, but I’m being greedy! Keep the work coming and thanks to you, Ton(?) and Chase!
Great to hear you appreciate this video. Yes, it was way cool of Chase to give us this much of his time. He's a busy guy with lots of responsibility and I almost felt guilty he spent that much time with us. It was a very educational experience for Thanh and I and I'm glad we were the channel Chase trusted to bring this information to the DIY Automotive Mechanic Public. Thanks for the comment and Happy Wrenching!
Holy cow! This video was a goldmine of information for me. I just got the diff out of my '85 last week and I've been prepping to get it back together... this video is by far the most informative I've seen so far. A+
You can thank Chase Perry for allowing us to visit his facility and film this video. This was a total gift, and we are stoked we were able to make these videos for the DilY Auto Mechanic Community.
I had ECGS do my 3rd member last year on my 2002 4 runner. I have to say they do wonderful work on these vehicles. My 4 runner runs quite and smooth. Think I will do another 300k on this 3rd member and then i will send it back to have them touch it up. Thanks again ECGS, You people will always get my business.
Thanks for chiming in Tim! We are glad you’re satisfied with your gears from ECGS!

I always pack seal on diff builds and pack the lip with grease keeps em from burning up while seating to mating surface...And its wise to put a little anti seizer on face of nut to prevent galking when tightenin to make it easier tightenin pinion nut
Thanks for sharing this info.
The most detailed explanation I've seen. Thank you Tim and ECGS
Yes, Chase did a great job documenting the regear/rebuild process. We were lucky to get invited to his facility to film it. You're very welcome Eric.
I was a little hesitant spending $2k on my yota diff from these guys… but now I see the difference and why it’s worth it. Can’t wait. Might even stop by in person and order it/ pick it up. I’m down in Florida. Keep up the great work everybody! 🤙🏼😎
They do great work, no doubt. They actually get most of their business from mechanic shops. Shops know they do great work, so they farm it out to ECGS to do the regear or locker installs for them. Private people like yourself sending in your diffs is the minority of the work they do. If you drop by their operation, tell the sales staff Timmy the Toolman says Hi!
Outstanding video. I just received my 5.29 ring and pinion from a reputable west coast supplier near me. Had I found this video prior to ordering I would have got the parts from ECGS as a way to thank them for all the information presented on assembling a Toyota 8” diff. In the future I will look to them for my needs.
Yeah, Chase did a real service to the DIY Community by making these videos with us. He's a great guy and runs a very solid company. If you haven't watched our interview and facility tour we did with him, I suggest you do. You'll be even more sold on ECGS when you're done watching. th-cam.com/video/ZS4fys3iFDE/w-d-xo.html
Got that same puller set! It's been great for me!
I’m a ecgs getting 4.88 and this place is amazing
Solid Sicmods bro! You’re going to like the re-geared life with larger tires!
- Sean
At 33:52: You can use the old bearings for pressing. Just cut the cage off and you got a perfect tool for pressing the new carrier bearings on.
Nice
Thanks for the tip!
my dad does the samething.. I thought I saw your 4runner heading into shaver on Friday.
@@TimmyTheToolman no problem. the same can be said for all bearings actually :). A flat plate on top for pressing or hammering.
Looks like that's what they did here actually. They just welded a plate to make things faster for future work.
You can also use the same plate to support the bearing if you happen to put it on in the wrong order.
@@shaunmilor It wasn't me!
A lot of impressive equipment in there, but have to say I like the cheap wal-mart pancake griddle/ring-gear heater
Yeah, simple and affordable can be good.
What an honor, congrats on getting your channel to a point that you're able to get your foot into doors like this! I wish this video was around when I attempted to re-gear my 06 Sequoia. I also wish my rear had the side adjusters, but sadly Toyota went a different direction with the first generation Sequoia, Tundra, and T100 diffs.
I found lots of good info on ZUK's website and put about 15 hours into my rear diff before waving the white flag and bringing it to a qualified gear wizard. I didn't have the proper pullers required to remove the bearings over and over again without damaging them. The important part was I gave it a shot, and actually ended up getting pretty close so the shop owner only charged me half price!
Thanks Gentlemen the Toyota community salutes you
Yes, it was a huge honor to be invited to the ECGS facility to produce these videos with Chase Perry. It was a total shot in the dark on my part. People had asked me to make differential regear videos but I didn't feel like I could present as well as people who have lots of experience with it. I sent a proposal to ECGS on what I wanted and was stoked to find out they were willing to let us visit and film the work in their facility. I was even more stoked with how much time Chase gave us. I actually felt guilty because he's a busy guy with a lot of responsibility. But, ECGS will be the clear winner from our partnership. For every guy who watches the video and decides to accept the challenge and do the work himself, there will probably be at least a 100 guys that say, that looks too involved and I don't want to invest that much time into it and afterwards still wonder if I did it right. So, the time Chase gave us was a good investment for his company. I already know of one guy who decided to buy diffs from ECGS because of what he learned from the Tour/Interview video we posted.
Thanks for the comment and you're very welcome. Stay tuned for the front diff regear with an Eaton e-locker install.
@@TimmyTheToolman He seems like such a humble and knowledgeable man...and he didn't really advertise his brand at all which makes me want to give him my business even more. I bought my gears, rebuild kits, and locker from them and it was a great experience. The communication before and after was excellent, and I can be a pest lol.
This video will be used as reference by people like me for eternity
Thanks again, looking forward to the clamshell video!
@@treehouseoffroad Yeah, Chase is a good dude. Most of his business has pretty much been through word of mouth, and based off the size of his operation, that's very impressive. Chase runs a solid business. He knows how to treat the people that work for him so he has a high retention rate. Because he can retain good people, the quality of their output is high. He's only going to grow as fast as he can so he can keep up with turning out a quality product. He also knows how to treat his customers. He has built a very successful business and he has much to be proud of. I'm very impressed with Chase and the company he's built.
No doubt though, the videos we made with him are going to increase his sales. I already know of a couple people that bought from ECGS because of our videos. He was smart to partner with us.
Thank you for the video. It was a great tool while rebuilding my nephews 8" third. Lots of good information.
You're very welcome. I'm happy to know our video helped your get your nephews 3rd member rebuilt.
This is a great video.
Diffs are one of the very few things I've never gotten into on a vehicle just because I didn't fully understand setting preload/backlash, but this definitely helped a lot.
Good to hear this video demystified differential work for you. Thanks for the comment.
Very good work guys..
I was surprised the baffle washer, oil slinger was not reinstalled.
I like what chase said about never getting the perfect pattern and the need to go either side of the shim set you end up with.
I especially like the point you make about being prepared to spend quite a bit of time to get it right..
The mechanical seal on the drive flange can be very good at keep large contaminants and grass from getting at the primary shaft oil seal. In the country we drive, see mud and long grass , we often see stuff wrapped around drive flanges.
For the center preload it’s often snug then a rotational amount ( an angle or number of notches) as chase said torque can be highly influenced by cap pressure and burs etc.
For the back lash I felt like the dial indicator was not perfectly tangential to the gear I expected it would only account for a thousands or so.. (my OCD) lol.
It also makes It clear why some shops specialise in setting up diffs. $$$ of special tooling and experience..
I have trust issues and have found some experts in fact don’t actually now what they are doing. The number of guys that get on you tube and do videos sometimes just exposes their incompetence.. lol I’m sure you know what I mean.
I would definitely use these guys to do my diff setups.
Absolutely no criticisms …
Once again great work hands down the best diff setup video I have watched.
Definitely subscribed from now on.
I would love to hear your and Chases opinions about solid spaces helping a diff that gets heavily loaded in the reverse directions, ie the dreaded reverse recovery pull.
Thanks for sharing all that. We got very lucky being invited to ECGS to document these differential rebuilds with Chase.
I never noticed that Chase didn't reinstall the oil slinger and that might have just been an oversight because we were filming and there was a lot going on and a lot to think about. After we were done filming, that diff went to one of his guys to recheck because the work done by Chase was more about showing the process and not getting everything perfect while we were filming. It was basically done this way to save time.
I don't have an opinion about the solid spacer other than it's a better way to go to avoid the pinion bearing preload changing if the pinion flange takes a hit during some 4wheeling.
@@TimmyTheToolman thanks yes he did say he was not happy with the pinion pre load they may have re fitted the slinger, but that would have costed a second seal.. I can imagine it’s hard to stay focused while trying to film it all.. man setting up the front diff is a big job..
@@stevehanwright481 We were lucky to get that much time from the CEO of a pretty big company. Since making this video, I've tried a few times to communicate directly with him via email or text and I never get a response. I imagine he has to decide who gets his time and I don't make the cut. So, when I need something or have another business proposition, I just run it through the sales department. I know I can always get ahold of one of those guys.
@@TimmyTheToolman as a business owner there’s an old saying I once heard I can’t keep everybody happy today so I’m gonna have to decide who it is I let down. it’s just impossible to contact everybody that wants a piece of me. I expect Chase is in high demand.
@@stevehanwright481 Yep, he's super busy and he has to find a healthy balance in his life. People are always asking me to work on their vehicles as a side job and I turn them all down. My time is better spent making videos where I can make an unlimited amount of people happy, rather than just one person happy.
I do have to say though it is nice when I can have some sort of relationship with the people I work with. It makes it more personal and rewarding. The best relationship I've made is with Yota1 Performance. I consider the owners my friends rather than business associates.
Your shop looks like a Home Depot!
ECGS has a lot of stock, no doubt.
This was quite the insightful video. Thank you ECGS and Timmy the Toolman and Sean for this video!
Glad you liked it Seydzh. I was stoked Chase agreed to let us film it. Stay tuned for the Eaton e-locker install into my front diff.
Great tip at the 16:35 mark for pulling the pinion seal. Hadn’t seen that before. Also interesting to hear he runs 85w - 140 gear oil. My understanding was both front/rear diffs called for 75W-90. Guess it’s just personal preference.
The factory spec is 80w-90 for the rear diff and 75w-90 for the front. Chase likes a heavier weight gear oil for the cling factor so it will give more cushion to the ring and pinion gears. So yes, it's the personal opinion of a guy with lots of experience in this field. I've decided to follow his advice and will be running 85w-140 from now on.
I agree with Chase. In all my excitement, I had used Mobil 85/90 full synthetic racing oil in my Toyora Hiace differential. It was not too long after that I started hearing a whistling noise coming from the differential whilst driving forward. I switched to the 85/140 non synthetic. The whistling noise was still there but it never got worse.
Best Diff video I've seen on TH-cam
I tend to agree with you. It was very generous of Chase Perry to spend so much time with us so we could share this awesome video with the Toyota DIY Automotive Mechanic Community.
Thanks for the great video! I'm going to try ECGS for my 5.29s in my tacoma. After researching it seams like the setup will be best for 34s with armor. I have been getting estimates from shops to install gears but now I'm going to try a 3rd member swap.
You can't go wrong with ECGS. Tell them Timmy the Toolman says hi when you talk to the sales staff to make your order. I met several of them when I visited their operation. Good luck with the swap!
Awesome video! Jealous of that arbor press, makes it so quick and easy.
Thanks Mark. We were impressed with that arbor press as well. It looked like an antique.
Just got my 8" rear diff with 5.29 gears and Harrop Elocker from ECGS installed a few days ago and it went off without a hitch!😁 Also installed chrome molly axles and disk brake conversion from LC engineering along with rear Truss kit from Trail-Gear, Hope my front diff from ECGS comes in soon so i will be ready to rock n roll .....hint hint😜
Good choice choosing ECGS. Your front diff will probably be arriving soon.
@@TimmyTheToolman well the thing is I priced out the individual parts and could have done it my self but it wouldn't have been much cheaper if at all and if I had purchased or took the time to build the few specialty tools needed to do the job right it would have cost me more
@@TimmyTheToolman btw I have stage 3 engine here from Yota1 I hope to get put in soon😍
@regularguy8592 Yeah, the specialty tools to work on differentials can be a little pricey, and if it's something you think you'll only do once, it's not going to be cost effective.
That's awesome you got a Yota1 Performance engine. Have fun with the install.
What a fantastic video. Thank you for this.
@@zee_nyc this whole series is pretty radical. Lots of good info with the owner of ECGS himself!
- Sean
The video we’ve all been waiting for!
I imagine it was worth the wait.
I did not unstake my pinion nut and it really messed up the threads on the way out and turned a one-day job into a multi-day job. I would have to recommend unstaking the pinion nut first before undoing it. Thank you for the video though tons of good info for a noob like me.
Yeah, I was wondering about that when Chase said there was no need to unstake the pinion nut. Sorry that happened to you. This is the toolset I bought to stake and unstake nuts: amzn.to/3j9AnPD
I added a pinned comment to warn others that they should unstake the pinion nut before removing it.
@@TimmyTheToolman good deal!
Thanks for this! Getting ready to build/rebuild a 5-lug 8" 2WD (G382) with a new Tacoma style V6/Turbo (really should just be called a 4-pinion) housing and an LSD from a MA70 G285.
You're very welcome, and good luck with the rebuild.
this video is exactly what i needed, i feel confident going into this now, thanks
You're welcome. Good luck with the job.
That was an awesome video! Well detailed and watching a true Craftsman at work!
We're happy to know you like the video. It was an awesome privilege to be invited to ECGS to film with Chase. I think we made other Automotive channels jealous. I was told by one of the sales staff that they have gotten calls from people wanting to film after seeing our video, and the answer is alway NO. Chase is a super busy guy and he spent a ton of time with us over the 2 days we filmed at his facility. I'm guessing after the experience with us, he realized this isn't something he really has the time for. ECGS has an awesome reputation in the industry, and he really doesn't need the advertising. Any time the topic of differential work comes up Toyota forums or Toyota Facebook groups, the ECGS name is always brought up.
@@TimmyTheToolman plus he's giving out a lot of Trade Secrets possibly two that might have something to do with it and like he said in the video you have to learn that craftsmanship it's not something you can just watch in a simple video!
@@KetoCaveMan Yeah, I was surprised they agreed to make these videos with us because of the trade secrets. But, this is what I think. For every guy that decides to tackle a differential rebuild after watching our video, I bet 50-100 will say, "That's too much work and requires special tools that I'll probably only use one or two times. I'm just going to buy rebuilt diffs from ECGS and call it a day." So, ECGS is gaining more business than they're giving away, in my opinion. I talked with the sales staff a few months after we uploaded the videos onto our channel, and I asked if people are mentioning our video when calling in to make an order. i was told they hear our channel mentioned all the time. So, it worked as positive advertising for them and I'm stoked about that. They are a solid company and I'm happy to hear our videos are increasing their sales.
Excellent video as always Timmy, thanks for sharing this awesome experience with them.
Keep that good content coming 👍👌
Thanks Bro! It was a honor to partner with ECGS to produce some awesome content. The front diff video will be out soon so stay tuned for that.
@@TimmyTheToolman cool
What was the point of doing the backlash before setting the pinion spacer and pre-load? You just had to do it again after reassembling, and redo the patterning. Why do the pinion first, then do the backlash once it's set?
We're not the experts. ECGS is. If you call them, maybe they'll give you the explanation you're looking for. Chase Perry, the CEO of ECGS, was giving the instruction in the video. He's been building diffs for a very long time, and I'm certain the methodology he used to rebuild the diff is solid.
@@TimmyTheToolman I figured it out - the first paint pattern sets the height of the shim separating the inner pinion bearing and pinion gear. That shim sets (partially) the dept the pinion engagement with the ring gear, which can move the heel-toe alignment.
Chase is da Man😎😎
Yep, he's a good dude to spend all that time with us so we could create a couple helpful videos.
Hi Tim. After visiting ECGS and learning all this stuff about differentials, do you still think the pinion seal replacement method you and Shawn show in one of your videos is acceptable? I watched this video to gain understanding on what is going with the crush sleeve on the pinion shaft and to understand backlash and preload. Chase mentions that it takes ~250 ft-lbs to crush the crush sleeve. Based on that, it seems the pinion seal replacement method you show in one of your videos should be fine as long as the pinion nut is tightened to exactly where it was before (counting threads/using paint marks). Doing so should reliably maintain the pinion bearing backlash, especially since it would take ~250 ft-lbs to crush the sleeve and change the bearing backlash. Does that sound right?
PS. I'm a big fan of the channel! Learned lots from you guys over the last year that I've owned my 02' 4Runner.
Yeah, I'm comfortable with our pinion seal replacement.method. We got the nut back where it was, so it should be fine. Sean has driven the vehicle a lot of miles, and there's no issues. If anything, I wish I would have tightened the nut more, knowing how much is required to crush the sleeve. I might have just barely undertighened it from its original spot. I know I was damn close because the spot on the nut it was staked before was pretty much dead on.
It's nice to know you're learning a lot from our channel. Happy Wrenching!
One thing I would like to add is it didn’t seem like the nut would turn anymore so any attempts to tighten it any further seemed unattainable. I believe we tried to see if we could get it any tighter and the nut would not seem to get any tighter and since the stake in the nut lined up perfectly to where it was before, we called it good.
- Sean
@@TimmyTheToolmanThanks for the replies! Did the job last weekend and now have a fresh OEM pinion oil seal.
@@ValkoDeath Good job!
Just in time. Thank you
You're welcome!
ECGS great people to work with...
We agree with you George.
I reset my password just to make this comment! Great video Tim!
Thanks Ben. This was a great opportunity for us to film with ECGS and we came away with some awesome videos. Stay tuned for the front diff video.
Awesome video Timmy! Keep them video coming! I just sub and like! Hopefully we can see more video coming from you!!
We're glad you like the video. Welcome to the channel and we will of course have more content coming your way.
This is gold ! Thank you 🙏
You're very welcome!
I own a 07 FJ and it has the 8” dif like in this episode. Typical for them to fail at 70k miles, ECGS provides a exchange rebuilt for them. At 130k miles I once again had to buy a ECGS rebuilt. If you own a vehicle with this 8” dif I can attest that its from shock to the gears (spinning free then hit traction) that will break them no matter how many miles is on your vehicle. If I ever need a replacement ECGS has my business.
Yeah, spinning the wheels is something to avoid if possible, because like you said, if the wheels all of a sudden gain traction, that can be very hard on the gears and axles. Easy on the throttle is how I wheel.
This is why I swapped my 8" for the newer 8.2" rear axle
@@nathanielfurman529 Id love to upgrade to the dana 44

great video keep em coming
Thanks! We will keep them coming.
I was patient. When do I receive my diploma?
That's a good one. There's no diplomas given out by the ECGS University. So, nothing you can hang on your wall, but you now have the PHD education in your head and you're better off for it. Happy Wrenching!
Great video!
Thanks Enrique.
To find carrier preload is Total preload - pinion preload then multiply that by the gear ratio.... For instantc 10 inchlb preload and you install carrier and you spin pinion with carrier installed and you have 20 inch lbs with unit assembled and you have a 3.41 gear ratio... Itll be 20 minus your 10. Multiply that 10 by the hear ratio and you habe 34 inch lbs carrier preload..... How i do it hasmt failed me in years
Very interesting. Thanks for sharing.
This is work very professional 👏
Yes, Chase did a great job presenting this subject matter. ECGS does very professional work with customers that are always satisfied.
Hey where can I find a bumper with a winch like the one on the 4runner for my tundra truck?. Thanks
Can you provide a time stamp in the video for the vehicle you're referring to?
@@TimmyTheToolman 1:35 the bumper on the 4Runner. Thank you
@@Raffuentes030999 That's a CBI Offroad bumper. They don't make it for 3rd Gen 4runners anymore. Maybe they make something for a Tundra. You'll have to visit their website and check it out.
Thanks again for this video !!! What gear ratio did you go with?
You're welcome Richard. I went with 4.88. I'm on 33" tires and 4.88 is about perfect for the tire size.
wait do you have to put the truck in 4 low to lock it? mine I can lock it in 2wheel drive. pretty sure the "chp" previous owner did the graywire sicmod tho
Yes, unless you have done a modification with the wiring, you have to be in 4Lo to engage the rear e-locker.
Apologies if this has already been asked... how much does it cost to send to them to do for you?
Give ECGS a call. Their friendly sales staff will explain everything to you. The best way to use their service is to order a prebuilt unit from them. When it arrives, you pull your differential and send yours back in the box they sent the rebuilt one in to satisfy the core charge. This way, you don't have to worry about how you'll package your differential and your vehicle will only be down for as long as it takes you to swap out the differential.
That makes sense! Thanks for the super fast response!@@TimmyTheToolman
@@mrgungho You're very welcome. We're here to help.
Am I tripping or what? Why do the both of you sound exactly alike?? Are you brothers??😂😂
Chase Perry and Timmy the Toolman sound alike? Maybe brothers from another mother.
Huh, which torgue wrench did you use on the main housing bolts, it's digital and not listed in the description, Percision brand? 40:43
I don't remember what brand digital torque wrench Chase used. For what part of the video are you referring to? A time stamp would help.
@@TimmyTheToolmanoh sorry forgot, edited 40:43
@@GuninGames Yeah, I've seen that style but I don't know what brand or model it is. They call them a Split Beam Torque Wrench. I believe you are correct though that it is the Precision brand. I think Chase is using this one. amzn.to/44awmwQ It gets good reviews too. Might be a nice one to get. I just bought a ridiculously expensive digital torque wrench from Snap On. I spent $830 on it so I could torque head bolts with the angle function. I think it was a waste of money.
@@TimmyTheToolman ok thanks, I've rebuilt my rear diff with a spartan locker and used a mechanical huskey on the bolts, almost over torgue them though, so I needed a more accurate torgue wrench
Ok, so on a stock toyota rear diff he's recommending 75w140 gear oil? Just making sure I heard that right.
Chase actually recommends running 85w-140 for every differential. If I understood him correctly, he likes the thicker viscosity gear oil for the cling factor because it will offer more cushion between the ring and pinion gears lessening wear.
@@TimmyTheToolman right. I can see that. The other thing I just saw was the recess on the pinion seal and chase mentioning toyota seals should be recessed. I wonder if that's all shaft seals. I'm thinking of the shaft seals on the CV axles at the diff housing. I've always set mine flush because I thought that's what I remembered from the very first time. Although I do know that on the 4th gen, there is a a flange, or sort if like a rabbet on the passenger side that I install it to, and that is recessed very similar to the pinion seal in this video.
@@TheDesertRat31 The recessing of the pinion seal is to avoid the pinion flange dust seal pushing up against the seal and giving you a false pinion bearing preload value.
The CV axle diff seals are recessed approximately 5.5mm from the outside of the differential tube on the passenger side or differential housing on the driver side. There's a step that they are inserted flush with. The Wits End company makes a cool seal insertion tool for these seals to make it fool-proof to insert the seal to the proper depth. We use the tool in this video th-cam.com/video/Q-RO52NtP1A/w-d-xo.html and we provide a link in the video description. Check it out.
Can you provide the part numbers for the bearings?
Sorry Derek, don't know the part numbers for the bearings. If it were me, I'd just order the full rebuilt kit from ECGS.
Thank you Timmy! Great video btw! Watched it a few times! Have a runner that is in need of a rear locker
@@darekpeterson4134 You're welcome Derek. Glad you like the video. It was awesome teaming up with ECGS to produce this video for the Toyota DIY Automotive Mechanic Community.
Excellent 😅.!!
Thanks Carlos! It was all Chase Perry though. We were just the cameramen.
Hey guys. Question, I just had my tacoma re gear and would like to know if I need to engage the 4x4 to break in the from Dif gears? sorry for the dumb question
It's not a dumb question. I had the same question as you did. This is the answer I got from Chase at ECGS:
Front Differential Specific Break-In Instructions from East Coast Gear Supply
*Normal 2wd operation will passively break in the front diff.
*Normal low speed trail riding under 20mph breaks in the front.
*Highspeed 4wd use for long periods of time should be avoided: Example would be road use above 45mph for over 10 miles, limit these types of drives until 500 miles is complete and oil is changed.
*Low speed 4wd use does not build heat, highspeed use does.
*Diff fluid should be changed if water is ever introduced, or after 1 year. No highspeed use for extended period of time, Change fluid after 500 miles of low speed, limited high speed use.
*Perfect break in would be fire roads, light trails under 20mph for 500 miles.
- Every customers driving patterns are different, the end goal is to limit temps above 250 degrees for extended period of time, a temp gun at pinion snout can be used to verify temps. As mention in video the front diffs hold very little oil. Diff drops and lower gear ratios impact oil flow to pinion bearings. Therefore, caution is highly advised for high speed use. Highspeed is defined as above 45mph.
-Note: This is specific to the 7.5 Clamshell referenced in video the larger Toyota front diffs T8 Clamshell holds more oil and oils better so is not as sensitive.
-Note: Main concern to cause issue is if user has brand new diff and jumps on highway in 4wd with low gears and diff drop, this can lead to pinion bearing failure very quickly.

@@TimmyTheToolman thanks for the information. Blessings
@@chocolon1129 You're welcome. I still haven't properly broken in my front diff. 500 miles is a lot of off-roading, so not exactly that easy to accomplish. It would be my guess that most don't achieve the magic 500 miles of off-roading at a mellow speed before forgetting about it and just driving as fast as they want in 4wd.
Hey Timmy !
👍
Hey William!
Yes I watched you removed pinon bearing without damaging
Yeah, I reckon Chase did exactly that.
Translation: hire these guys to rebuild your diff.
Yes Ty, you can't go wrong with using ECGS to do your differential work. But, I feel with the right tools and right level of patience, you could rebuild your rear diff using this tutorial. It would be challenging, but it could be done because of what Chase shared.
Please help! I have ‘00 4Runner v6 and it stalls out on steep hills while climbing in 4wd and usually when the wheels are spinning 😵💫. What could cause this?
If it's only on steep hills, it might be a fuel pressure issue.
I’ll try to get it tested and run some cleaner through it. Could it be the crankshaft position sensor?
@@arnoldarriola2171 If it were the crankshaft position sensor, you would throw a code.
@@TimmyTheToolman thank you I appreciate your help!
@@arnoldarriola2171 No problem
Timmy do you have the font deferential video with locker also or it was only the rear one?
Yes Arin. That video will be coming out within the next week or so. It's not as complete because Chase didn't want to show some of the same steps he did the day before like pulling off carrier bearing and pressing them on, taking off the ring gear and putting the new one on and discussing setting pinion bearing preload. So, I'm just going to mention that fact in the intro of the front diff video and suggest people watch the rear diff video first to get a more complete picture of the process.
We will also have a Part 2 for the Front Diff Swap where I share more information, mainly some tricks to getting the diff out and back in easier.
Finally, we'll be putting out a video for the wiring of the Eaton e-locker. So stay tuned for more content....
Awesome. Thank you Sir
@@arinmirzayan3949 No problem Arin.
Starting out right around the 6:46 mark in the video when he flips the Diff over to show what’s happening when The actuator motor is locking and unlocking the diff he is pushing in and pulling out that part that has the fork part on it(sorry not sure exactly what he called it) when he pulls it out he says the Diff is unlocked, when he pushes it in he says the diff Is locked. On my third member I am not able to push that part in if I put a pretty good amount of force on it I can get that part to start pushing in but can’t get it to lock in position. Any idea what could be causing this? It is currently in the unlocked position but I am not able to push it in like he is in the video. It looks to me like he is not using very much force to push that in and sometimes just tapping it in with the side of his hand. On mine I am having to push it in pretty hard to even get it to start sliding towards the locked position. Thanks for any help you can give me on this.
That's the shift fork and locking collar he's manipulating. You are correct he wasn't using much force to move it. Maybe yours hasn't moved in a long time and some gunk has built up on the gears. I'd spray some penetrating oil in there to try to free it up.
Tim thanks so much for the reply. I will try doing that and seeing if it makes a difference. I can get it to slide in maybe an inch to inch and a half but it takes a decent amount of force. Definitely not as easy as the one in the video. I’ll give that a shot hopefully it will free up.
@@rthomas2157 You're welcome. Hopefully 6ou can get it moving more freely.
Total bone head move on my part. I still had the actuator motor installed while pushing in on the locking collar 🤦♂️. I took my third member in to a local guy that has a lot of experience and is very knowledgeable about these diffs. The first thing he asked me is if I had taking the actuator motor off. As soon as he said that I realized my mistake. Oh well lesson learned. On the plus side he said the third member looks to be in good shape and everything is good to go. I picked up some Toyota FIPG and new crush washers will be installing it this week. Tim thanks again for all your help and making these videos 👊
@@rthomas2157 Gotcha. I just assumed you had the actuator disconnected like we had in the video. Good luck with the install.
Lost art, just had to buy a whole new front clamshell which was a cool 1000+ because no mechanics in my area take the time for this type of work…not worth 140 /hr apparently
Well, now you know about ECGS. Lots of people ship their diffs to them because they do great work for a reasonable cost.
Or... Just send it off to ECGS and know it'll be done right.
John, we can't argue with that. Doing this sort of work isn't for everyone. It takes special tools, lots of patience and some expertise. But, with this video, I'm confident a DIYer could do this job with a high level of accuracy. ECGS is an awesome company and you can't go wrong letting them handle your differential work. Thanks for the comment.
Hiro men
Hiro back at ya.
Very Satisfied " Excellent"😅.!?
Thanks!
