For keeping dirt out of the motor housing I use a thick grease around the opening. I'll even put some in the grooves where the housing mounts to the chassis so it comes on and off smooth. I have not got dirt in the housing yet it works great.
I spend more time repairing my big rock then using it. I got it for my dogs, they love chasing RC cars in the back yard so I’ve never jumped it or anything but have replaced probably 8-10 major parts on it…. I suggest going the next size up
On my arrma typhon I broke a few plastic diffs when driven very hard, BMX track and big jumps. Upgraded to the metal diffs and they have been holding up pretty well. I make shure to grease the diff very often and it feels like the car is rev’ing much faster, sounds more angry and more punch in the throttle. They seem to hold up very well, so my next upgrade might be a 4s setup. I like the 3s rigs, they are so easy to work on and I know all the weak spots and have my own «fix» for many of those. And I always «paint» my car with WD40 wich make all the plastic very flexible so it hardly ever breaks.
I switched to the cnc parts the second time my rear input gear blew out. The second time I realized the diff was shimmed on the wrong side from box stock. No issues since.💯 Love This Truck.
I have the Arrma upgrade diff on the way. You still use the shim? Which side do you have it on now? Ring side or opposite? (Stock is usually ring side).
Good to see you! That's normal wear. The out drive pinion teeth sharpen to a point and then snap off, destroying the diff gear. If you catch it before the teeth snap only the pinion needs to be changed. The hot racing setup in front and back don't effect the power at all on my outcast. The plastic yoke flexes miss aligning the gears . The hot racing aluminum yoke will slow the wear! Check ebay and Amazon through hot racing site!
I ditched the metal CVD driveshafts. Main reason is you can't use the Typhon axles with them. I snapped/bent alot of stock axles. Second reason is I actually snapped one. Popping u-joints is a problem with the stock plastic, but I've NEVER snapped one. Third reason is the significant added weight which reduces performance and durability. So far loosening the slipper (1-1/4 from full tight) seems to be the solution to using stock plastic driveshafts without popping u-joints often.
I've been having problems with my big rock.. when I accelerate it makes that crunchy sound and I thought it was my slipper clutch but I checked and everything was fine.. checked the diffs and everything was ok too. Then I checked the screws maybe I made a mistake and screwed all the way in the diffs but nada. Applied grease and all that but still the same. Still makes that harsh crunchy noise when accelerating and low speed. 😔😫
I just stripped my 3rd rear differential/input gear. The Hot Racing yoke may help, this 3rd one lasted longer. But the 3rd input gear/diff got stripped shortly after adding the M2C motor plate/chassis brace. It may just be coincidence but I think the added weight/stiffness may have something to do with it. I still need the motor mount plate, but I'm going to try it without that really heavy chassis brace this time. If the diff still goes I'll try the backordered CNC diff/input gear. As others have said, the front diff doesn't suffer like the rear does. So far, I'm still on the factory front.
On those rc the chassis and towers is the housing, unless you overpowered ,you shouldn't be stripping the input gear , ive been through only one ,with 6s ive been through a dozen , if you are powered with big can motor maybe try a t2t brace that and changing the case stopped mine from stripping, on 6s , the 3s I stripped one but after 100 packs run through and I thicker diff fluid , that can put more stress on it also , make sure those bearings are near new conditions also
@@paulclancy2404 My bearings have never been the problem. I'm not stripping from overpowering. I'm on 3s, 15t, the slipper is nice and loose, I don't wheelie and I don't land on throttle. The damage always happens after landing a big jump. Impact to the back end flexes the rear diff and input gear, they get thrown out of alignment and strip each other. That's why the Hot Racing yoke helps, it reduces the flex. The chassis is fairly new and my 3rd, but a warped shock tower could be a contributing factor I didn't consider.
@@tyrellcorp2118 yes and all you young guys killing jumps , should immediately install a t2t brace , its not as cut and dry with the arrma 3s I suppose but still would help and looks good too. When arrma copied bashers with theres it helped but no where near as effective bc not connected to the towers ., and guys just started pushing m2racing chassis.aluminum diff cases. I get aluminum tubing from home depot , threaded rod run through the tubing with nuts on outside each tower , you can even use wing nuts and adjust the rigidity, with plastic rcs ofcourse just want tension
What axles are you running? The inner section look like the axles off of the Kraton 4S. But I have a V3 Big Rock and it didn't come with those axles. I also looked at the parts diagram for the V3 BR. And that also shows the axles mine came with.
This show is awesome..at least a new viewers knows what is all about .thanks for sharing..i will follow your step how and how to set up the rc cars build.thanks for the tips🤘🏻💪🏻
Looks like a 21 tooth pinion??? What temps you getting??? I tried a 20 on mine but got motor way too hot dropped down to a 16 tooth and getting 54 mph ... plenty of power and probably save parts from breaking 🤔...all in all got one cause of your vids man and enjoying it !!! I say keep it stock drop few teeth on pinion it’ll blast for infinity!!! God bless
You literally saved my day! haha. I was getting a bit "bored" of other vids on YT, cause they don't have the classic RC Guy Garage energy! lol. This vid brought me joy just to click on it! haha :). Glad to have you back! :)))
Good episode. Tho I would say in the Arrma 3s line....if your gonna keep it at 3s and not upgrade the power system (3s puts out plenty for bashing) stick with the stock diff components. Way cheaper, can get 3 complete stock diff parts for the price of the upgrade and the stock diffs hold up just fine. Getting proper slipper tension is the key.
I order parts like I order fuses. Order one and it's gonna blow. Order two and it'll never blow. If the parts aren't really expensive, I order two. I like parts in stock to repair the car while more parts are coming in. Good video. Thanks.
Guy!! Where have you been? & now you have 4 screens for us to look at, main, you face, tablet, and the phone infinity screen, you're making me multi-task😂. I've had exactly the same issue with my big rock and blew the rear diff 😢.great vid👍
If you wind up going with the Arrma steel input and ring gear, you might consider picking up some 12x15.5x0.2mm shims. I needed all four on the input side to tweak the mesh to keep it smooth.
I’m about to replace my rear diff with metal one. I don’t have any grease. I notice yours in greased on outside. Is that necessary? What grease do I use
Do the Velcro mod on the bottom of that unit. Use the non abrasive part of the Velcro and put a piece around where the gear is it keeps a ton of crap out of it
Excuse me if you already did a video on it but I’m trying to find a rear drive shaft solution I don’t wanna buy the CVD’s if there junk ?😇 I hate to haft to leave my slipper clutch so lose lol
You didn't have to do all that to get the diff out...just undo the 4 screws underneath and the top lifts up with arms and shocks etc, u can the lift the diff out
Double cam? I'm seeing 4guys now that's too much guy 😜 and can you please put your soldering station up for sale I need one and have made a copy but I don't feel comfortable using it without at least pay some copyright 😁

Don't you dare put the vortex system in the big rock. I'm not buying another Domn truck. Just put the upgrades in the big rock so I know what I can do. Lmao. All kidding aside. I only have the big rock and crawlers. When it comes time I'll check out other channels for the esc upgrades if I have to.
I got my big rock used with upgrades guy said but there's a place called king Cobra of Pensacola and my big rock has been the 4 time each time I tell them I won't a upgrade they say ok I get it back and. With in 5 minutes of me driving it I don't ramp and dog it I can hit a bump and it with start slipping I spent 2,000 on rc cars because and not one works got 4
Idk why you make it sound such a drag you have to tear your RC apart lol maintenance and diff maint and maint period is a must if your doing hobby grade Rc lol not maintaining is why things fail
Maybe the rear went bad because 100% of the power was going to it when you ran it in 2 wheel drive for a while? Just a thought.
YES!!! You are the ONLY one to mention that so far!!! I did a BUNCH of launches on that thing on AND off camera testing gearing and tuning
I didn’t think of that. Ya and the 500,000 miles on it. Lol
No, it's the heavier impact the rear takes. Everyone has problems with the rear diff, no one has problems with the front diff.
@Riff Raff's RC Agreed, but I really don't think I land on throttle, so careful driving may not be enough to save the rear diff.
@Riff Raff's RC Guy will keep her going! Maybe run front wheel drive now!

Arrma has the metal upgrade(u need a diff cup for them) and also get the hot racing diff yokes and you will never have diff issues again

Drill a hole in the chassis bottom were the spur sits so dirt wont be stuck there. Also the rear diff strips because the input gear bearings have slop

Not CHEAP for a CHEAP MODEL
have found the arrma upgrade diff cases hold the internal gears to snug, cant even move them? you have this problem
@rcguy garage it’s only 4 bolts to pull the entire differential out,your doing a bunch of extra work my friend.hope this will help you in the future
Right except for video purposes I need to remove top housing to show damage and clean out the gear chips
People in the Arrma fourms drill a couple of holes in the chassis so dirt can fall out.
Yes I've been thinking that exact thing
I noticed you had some sort of purple grease in your diff housing. When I had to replace mine I put white lithium grease in there. Is that acceptable?
Could be but that was only a test with the purple I've reverted back to the Orange
If you wind up going with the Arrma steel input and ring gear, you might consider picking up some 12x15.5x0.2mm shims. I needed all four on the input side to tweak the mesh to keep it smooth.
