3 minutes in, and my jaw is on the floor....I've never heard a bearing that loud in my life, and I live in St. Louis, where car maintenance is fix it when something falls off.
Yup. Sounds like the bearings are made of sandpaper. 😅
im wondering if somehow the noise rapidly got to that point, of if the owner is REALLY good at drowning out expensive sounds haha
270 junkyard specials
Ray bravely drove it further down the road than I would have dared.
Hey not everyone, my vehicles are very well cared for here in Arnold
Dave’s rapid response to your request is phenomenal. What an assistant! You are blessed to have Dave.
What a difference a Dave makes. I'm also a Dave
Sounds exactly something Dave would say.....
I've been laughing and giggling since the noise started. HOLY COW!!!!
I have heard louder - Back in the 90's when we had the 84 dodge caravan, a bearing went bad and you want to hear loud while on the Hiway... us 94 from MPLS mn headed west back to north dakota... heck that was louder than this! the Wheel bearing went! I think this was in 1995! we no longer have the van! Thank god for that!
Oh hell yeah! As The official bearing aficionado of this channel, I wholeheartedly endorse bearing videos!
That familiar bearing helicopter sound.
OOF that one is a growler! I think what happened was someone replaced the pinion seal and smoked the nut on without thinking about the preload on the pinion bearings.
Grin and Bearing it
I saw what you did.
Your theory of someone putting incorrect preload/tightness on the pinion may be it. I thought there was way too much backlash, which could be related to that. A full bearing overhaul, and limited slip too if the owner approves may be the ticket. I look forward to the followup video. Thanks for another great video. 😊
Exactly my thoughts. Preload on crush washer. Pinion bearing too loose.
Peace.
Thumb up for Dave! He is excelent mechanic like Ray, hard working and always happy. He is keeper for sure. I salute you, sir!
anyone else watching the truck in drive on the lift going down secretly think "what if the lift failed and the truck went sailing through the back of the shop" that would make the highlight reel for sure. Love the knowledge and commentary from Ray!
I kinda agree that this test is best accomplished with another in the driver's seat.
In
That thought did cross my mind.
"Let's put this down." Wheels still in drive. Not a good idea I'm thinking.
Like Sleeper Dude says you always want to check your rear end because no one else is going to do it for you!👍
Ray spinning the axle with a drill is every mechanic’s second childhood dream. Including myself!
Yeah, I liked that too.
Yeah, I have an f150 and it sounded very similar to what that one did. I took it apart and things didn't look to bad. But I could tell that at some point the pinion nut had been over tightened. You could really see it on the races. I think they were trying to compensate for an incorrect spacing between the pinion and ring gears. Since I was unsure about what all had been done to it. I just rebuilt the whole thing. I've had no worries since then. Although every once in a while I'll hear a high pitch clicking. Sounds like a U-joint to me. But the odd thing is that it just comes and goes. I can't seem to find a reoccurring situation that would making it happen. It's just completely random and goes away as quickly as it shows up. But, it is a Ford. Fix Or Repair Daily 😕🤦♂
Rather fix or repair daily, before I’m found on road dead…..😂😂
FORD has been around a long long time... so never forget: First On Race Day.
@@tomtke7351first on race day. Last to the finish line lol. F****ing old rebuilt dodge.
@@tomtke7351 First On Race Day.... More like Fucked On Race Day!
Just kidding, I have no hate for Fords.
“It’s ‘limited slip’ only until you spill lubricant on the shop floor. Then it’s ’unlimited slip’!” 😅
Okay, for a Friday I laughed too hard at the glove being put on….. 😂😂😂😂
1) it's a crush sleeve, not crush washer.
2) That is not a limited slip differential, that is an open diff. Those "clutch packs" are actually shims.
3) Yeah, someone over tightened the pinion. The races are probably not smooth anymore. I had one that actually cracked the race. Snap on makes special punches to get at the races - highly recommended (under the category - the right tool saves you lots of time).
4) I've never seen diff fluid look so much like water and have soap bubbles in it... That's supposed to be 90 weight??? How hot is it in Florida?
New bearings should be set for 25 in-lbs drag torque. That includes the side bearings.... There is no way a diff should have fallen out like it did. Recommend you install the diff without the pinion, set the side pre-load, then install the pinion. I would also check the backlash and pattern just to be sure. Someone's been in there.
Tapered bearings are supposed to have pre-load to survive.
I like getting differential parts from Tom's Differentials. When Tom still owned it he gave me lots of advice on my first differential rebuild and gear swap after I messed up the first set of gears (I was too loose on the backlash).
I would also recommend getting the GM gear marking compound. It is yellow, contrasts nicely with the black metal parts. Heck, by an install kit from Tom's. I think all of them are Timkin, made in USA bearings.
BTW, are the side shims under the bearings? Is that a Dana? I hate Dana's for that reason alone. Give me a GM any day over a Dana. I know Dana 60s require pinion spreaders to make your life easier - but they are expensive. See OTC.
BTW, before I did my own rear end work, I found offroad and 4x4 shops were the most economical way to do it. Those guys did gear swaps day in / day out and it was something like $500 / axle. Now a days, the gears alone would probably cost that.
Sorry for the long response
Maybe he torqued it to 25 ft lbs.
Dave's new nickname will be Radar
That thing sounds like an air raid siren!
Morning Ray- I got nervous when you were under that truck with the engine in gear ! Just me I guess !
Nope, You were not the only oneJack
Then you fundamentally don't understand physics.
@@williameldridge9382Well I guess I don't fundamentally understand physics either so please explain how they are applicable in this scenario.
No. Not just you, but I was more concerned as he lowered the truck towards the ground with the driving wheels still powered.
@@alanclarke2524 Me too I that's why I asked @williameldridge9382 why he responded we don't understand physics because of our concerns. He has yet to respond so must be a keyboard troll.
That proctologist snap of the glove when you had to 'go deep' for the retaining clips got me.
I have driveshaft banging with slop between forward and reverse shifts that I've isolated to the rear end as well as a high speed vibration. I need to takle this same rear. Glad to see the job before hand. I will be Closely taking pointers on the part 2 reassemble. Thanks Ray
Sounds like rear universal.
@@bobherweg6442check the universals first
@@bobherweg6442 I replaced the drive shaft it is all brand new. It did help, but the vibration is still there. New tires and freshly balanced. Alignment was checked and redone all good. With the drive shaft disconnected from the rear end there is a notable amount of play moving the pinion flange forward and backwards and all of the drive shaft play that I can feel in the shifter goes away I cannot move the drive shaft at all connected into the transmission so there is no play in the four-wheel drive or transmission once disconnected from the rear end. Last thing I need to do having done all of that is to crack open the rear end. I think I have a broken bearing race or cage in the pinion part of the rear end assembly
"Hey! It's that guy." That was IMPRESSIVE.
Wrong channel. 🤣
Baseball cards in the spokes
Poker card is better since it’s laminated
Once I saw the tires, I remembered the truck.
"Using the whole fist there doc?"-Fletch lol
Best movie EVER
Full bearing rebuild is in order if the owner is going to keep truck. Otherwise, minimum replacement.
when you put the gloves on, the first thought that came to mind was bend over and cough. lol
I mean he is servicing the rear end
😂😂😂😂 @@Bfaided
And both hands on the shoulders!! 🤣
The coughing is for hernia check. Bending over is prostate.
What kinda Dr you going to that wants you to cough after bending over? 😂
@@doncnunez6231😳!🤔? 🤣🤣🤣
may favorite use for used newish oil is drill bit lubrication
And used transmission oil makes a grate winter rust prevention up north.
Following up on a previous comment I made about Dave being quoet and that is why I like him as part of your channel.
Back in the days before your own shop, there was a video where you changed a compressor on a ford van. One of your coworkers came to tell you to make sure to have the bolts in the compressor when reinstalling for the clearance.
I am sure that mechanic was trying to be helpful, and social. Or at least trying to get through the day.
Dave is recognizably skilled. When he helps you out, he makes sure he understands what help is needed, and doesn't try to one-up you
Dave probably quiet because he can't get a word in over Ray's talking!! LOL. (Just Jokin' folks)
Perfect example of why bearings have to be tested under load. Nice work!
Pinion preload and mis adjusted ring to pinion gears
Thanks!
"I need a little bit of protection for reaching deep into the rear", and upon reassembly, we recommend a tube or two of Desitin be applied to the affected area of noise, I know it works for me!
Looking at those back tires and weirdness with the pinion bearings, I bet a kid has been out doing power brake burnouts. I use to see this a lot in the 1990s in V8 cars from the 60s, 70s, and 80s. I hope you get this job for a full rebuild.
holy moly there's space in the yard. Could do all sorts of activities in there now.
Good honest work.
Good Day Ray and hi to Dave
You have the patience of a saint and evidently the heat resistance of a camel. Maybe I am just getting older but I can't do the simplest thing with my car anymore. Within 3 minutes my clothes are soaked in sweat and shortly after that my glasses are also covered and I can't see what I am doing anyways
RAY! I subscribed to your channel about a month ago, been watching a ton of your vids. Today, I go to check on any new vids only to find out I was unsubscribed, had to re-subscribe. Something wonky with TH-cam because I damn well didn't unsubscribe.
Yea YT does that all the time. It’s really annoying
Interesting. Can't wait to see the rebuild.
Shop looks fantastic.
Great job
I noticed I was holding my breath when he was lowering the truck 😎
Great video..
Limited slip? I don't see any springs or clutch plates, also there was no tag on the cover bolt to use special additive.
Wow. Just wow.
Welcoming back!
I like the video and WOW amazing TY so much ,,Keep up the great work
I’d have to agree with you ray. The rear end in this ford is super finicky and if someone torqued it down too much it will make that sound.
I’ve been a fan of the Axel Saver Bearings anytime I’ve ever had to work on a rear end. An Axel Saver is built the same as a regular bearing, except they’re wider (double thick). It allowas you to keep an axle that otherwise would have to be replaced. If you’re working on a budget, they are lifesavers.
the soft preload on the limited slip clutch sprags would be enough to prevent diff action without any load on it
Great video! I haven't done much differential stuff, only one has ever failed me on a Pinto station wagon in the early 80s. A $75 used rear axle at the wrecking yard solved that one.
Blown up u-joints,yokes and blew a spider gear threw the rear end housing 😢
Brave man to admit to owning a Pinto
@@DanielJohnson-ec8rkMy first car was a sh*t green pinto wagon. It was the 70's and I was so happy to have transportation. It wasn't like today with spoiled kids that don't appreciate what they have.
@@DocZoidberg549 when I was 17 I bought an 82 Trans am. This was about 1989. My insurance was $300 a month for bare Minimum liability. After 6 months of paying for insurance, I traded it straight across with my mom’s mechanic for an AMC Pacer.
Yes, it’s true. Now that car was embarrassing but cheap and reliable
Finally a new tool box appearance🙂
Good video, always learning stuff. On what to do.. and not to do. Like filming under a running vehicle 🚗
Not related to this video, but I want to mention that Ray's lines even reached The Netherlands. I had to change the light bulb on the front of my car. To remove the whole unit (thanks Volkswagen) I said to myself that I have to "popping zee hood".
thats a hard diag but of course you got this your rainman ray! cant wait to see the rebuild if customer agrees.
Happy Friday Ray. Noise instead of Words. Wow sounds like a sewing machine on its last legs.
Morning Ray
Dang man, your shop sure has come a long way. It’s looks great!!
I dont know what you did but the only time o heard any difference at all was right at the diff cover
Had the same issue 2 times with my 1988 E30 325is BMW.... Ended up doing a complete rear diff overhaul.
Great video Ray Man interesting mate 👍
I would start looking for recycling yard replacement part.
Like to see another part. For some odd reason this truck fascinates me. Been enjoying watching the videos on it. Of course, all your videos i find fascinating. Great job. 😊❤
Just had mine replaced last month same noise. New diff and bearings all around. Worked great did complete break in procedure. 3500 miles later same whining. Going back to shop tomorrow.
Simple, just turn the radio up. No more differential noise!
I agree -- if it were me I'd replace all of the bearings and associated parts, maybe even the center section as well.
I believe you are correct. The adjustments had been tinkered with for those bearings, causing a lot of stress in that diff. Good catch!
Opening test drive sounds like a swarm of angry drones
It is a very common problem. I had a 2008 that did the same. They were originally recalled. If noise just started it can be shimmed. It's just the gear alignment. Even when parts look perfect. I had to get all new rear end parts from driveshaft yolk to inner wheel bearings.
Love that bearing noise. Ray I hope you and the wife unit are doing well.
"A noise" is an understatement. Holy heck!
What a unique anti theft alarm.
Those pinion races are Toast 😊😊😊
I watch all the time. When you pulled into the shop today I didn't see your sign for the shop! Give a look at it when you get a chance. 😊
my brother had same issue 3 week ago ford f 250 found bearings were bit tapered customer did rebuild come out great
My Camaro had the diff howl twice until I replaced the gears with Yukon gears and upgraded the ratio 😅
rear differential rebuild looks like the way to go
Hey, you can mix that with a little bit of regular drain oil and use it for chain lube on your chainsaw. I’ve been doing that for years.
new parts kills the doubt and fresh parts.
I think you missed the noise - To me it sounded like the back lash was Way to Way out of adjustment and if you look closely to the ring gear at the outer tip the pinion wasn't set right and was extremely loose. Bearings don't sound like that They just growel
I concur, it sounds like a bike with cards in wheels attached with clothes pins
The first 10 feet was enough for me brother 🎉🎉
you are that far in ray!
Waiting for part 2
I think it's the inner pinion bearing race. just an observation. I agree rebuild the whole rear end or put a used one in it. Great troubleshooting method.
Curious to see if one of the pinion inner bearing races is cracked.
nice cobra!
Same rear-end as my 2003 Dodge Ram 1500 5.7. Mine started whining bad at 243K.
Sounded just like this except no play. The siren was running!
It was the large pinion bearing race failed. It was quite pitted and pieces flaked off.
Bearings weren't that bad.
Had to clean all the metal flakes from the entire axle.
Replaced all bearing, races and seals as Ray is doing here.
Installed a Truetrac unit and did not deal with the crush sleeve but instead utilized one of the kits that has shims.
Took a little trial and error but got it all perfect.
Now 10K later and still perfect. Nice thing about Truetrac is that it has no clutches to wear out as the clutches on mine were worn out. New trucks are too expensive so I invest in mine for the future.
Compared bad race to pictures on internet and clearly showed that it was metal fatigue from the miles of use.
Rainman Ray.. I would definitely do a complete rebuild on it. And now is the perfect opportunity to change the gear ratio. Why not, right?
The U! 👐🏼
I had a 1978 Dodge Aspen with locking diff. A special additive fluid , four ounces)was required to be added to the differential to quiet the clutch packs in it.
new bearings and seals all the way around and hope the owner understands that the diff would be a good choice to change also. Rear end would be good for the rest of the trucks life.
If I was the owner, I'd let you do the full meal deal on the axel. You've already got it taken apart.
When you show the close up of the bearing race at 24.04 you can see it has ridges in it; the rollers falling into these grooves is what is causing the noise, essentially cogging. It could be an under hardened race or it could have been someone putting way too much preload on the bearing (its probably a combination of the both)
Digging on the cobra
Least of your worries with that year F150. Pretty sure that thing is part of the recall that is due to the trans downshifting to first at any speed. Quality UAW made vehicle!
I'd replace all the bearings since it's already apart and perhaps the clutch (friction ) plates if the wrong differential lubricant was used. Looking forward to part II.
It really sounded like the pion was slipping I'm surprised it didn't chew them up.
If it was mine I'd take this time to do a full rebuild and upgrade to the way he drives either speed or power like you did on the Jeeps.
He can always sell the used parts as a set.
When you drove off with that Helicopter sound, you drove it further than I would have ... I was waiting for the diff to explode
So how does Dave like his new Box?
