Awesome info, I just got an old T MAxx as a gift and it was every bit as filthy as what you had there, slowly taking it all apart and learning what's what. awesome how people share this info, truly great. Thanks.
If you want something even more indepth, I am right in the middle of rebuilding a 2.5 T-Maxx. Check it out. ruclips.net/p/PLabJwbJaz4QuWqKXO5IQByu8D6_rn2c9F I love doing this stuff, and I'm glad I could help out. www.Rc-Help.com
Great instructional video. In the process of rebuilding my T-Maxx 2.5 that's been in storage for 6 years. Factory grease in the cups turned into TAR. (Don't store your RC's in 100+ heat in the desert.)
I rebuilt my differentials last week. I put CVT Transmission oil in them. They are not sealed differentials, so I just put a little bit enough to keep them moisten, but without any leaks.
I own Mini e-revo and I love every second. However, I broke electric part a few days ago (I think it is either ESC or Receiver) so I am going to try fix this weekend.. Anyway, I am looking for get 1/10 scale one aside from that and I was thought about either slash or T-Maxx and so I am learning ahead.. Again, I am newbie and your video is one of the best video that I've been seen and even though I don't have one, I can easily understand and apply to other one when I am needed.
i did this to the same truck but 3.3 trx just 5 years later... the grease was disgusting it was like very thick glue. thanks so much. im completely rebuilding
I got it. At least you have a skill to all fixed up and clean up nicely.. It will be years for me to get there :) BTW, I will check it out the site.. Thank you again,
Cleaned up my differential and reassembled. Spun it and noticed the metal gears didn't have the correct meshing. I notice on the exploded view of the differential. There's a Teflon Bushing that goes into the cup. Traxxas Part #3981 (Traxxas Teflon Washer 6x9.5x0.5mm). Installed the bushing, now my gears mesh perfectly.
great video, big help. I have a problem with my E Maxx. I continue to knock driveshafts out of its sockets connected to the diffs. It started after i melted the stock drive shafts and replaced them with the Traxxas steel drive shafts. If you can help me please let me know.
I just bought a Stampede last week and I am getting leakage out the side of the front diff. That and when I took it apart everything appeared to look just fine. Diff oil was way black. I didnt replace it I didnt have any at the time. But upon reassembly the output shafts had a bit of restriction on them. Im just a bit concerned about that. That and any tips on keeping it from leaking?
My tmaxx I just put back together when you spin the rear tires the front tires spin in the opposite direction therefore keeping it from freespining do you know what I done wrong or what is causing this?
FYI: Both front and rears did not have this washer installed. T-Maxx Classic owners, check your differentials. The old saying, This may have been assembled on a Friday or Monday. LOL!!
I don't have a parts washer so if i used water + washing up liquid, how to I prevent the metal from rusting from the water. I know this may be an obvious question but I'm not sure.
You can absolutely use just soap and water. Just spray it down with WD-40 when you are done and it shouldn't rust. The "WD" in WD-40 stands for Water Displacement, so it repels water and keeps the metal from rusting. You can also just dry them off really well and put grease on it and install it in the diff housing. But if they are going to sit out for a while, definitely hit them with some WD-40. www.Rc-Help.com
it seems as though someone before me has put the diffs in backwards because my truck is in reverse, has this happened to anyone before. should i swap them around>?
I've replaced the rear diff on my T Maxx 3.3. The wheels spin while off the ground but when the model in on the floor it doesn't move. I have checked all grub screws on the driveshafts. If I put all left, right, front or back wheels they will spin freely on the ground but not all together. I'm thinking that it has a gearbox problem. What do you think?
If it is a true sealed diff, such as on a Mugen 1:8th scale buggy, then you will need to use the appropriate oil rather than grease. At least I would. On those diffs, you can use oil viscosity to tune how the vehicle turns. Some of the oil is almost like great and very thick. But I would definitely stick with what the manufacturer recommends.
Thank you so much for the reply back. I have T-Maxx 3.3 and yes the diff are sealed. Now I just need to figure out the recommended oil for the front, middle, rear. I don’t do anything special with it I just drive it around the the front yard an on the road.
I'm going to have to say no on this one since every part number on the diff's are different. The bulkheads are the same, but the diff housing, gears, carrier, driveshafts, all have different part numbers. I'm thinking just more beefy to handle the 3.3. www.Rc-Help.com
Something is probably binding, or you have some thick grease in your bearings. This was done (the free spin) on a completely dry setup, no oil or grease. www.Rc-Help.com
RcHelpDotCom when yours was spinning without the lube. Mine don’t have lube, I’m trying to build one right now, I’m not sure if it’s because I didn’t apply wd40 to the bearings tho.
In all honesty, as long as there is no tight binding, it should be fine. These trucks are large and heavy and a free spinning diff like I had is definitely not required. Mine could have been because it was worn out, or I could have clearanced the case (I honestly can't remember, it's been about 8 years lol) to keep it from pinching the output bearings. Either way, as long as you don't feel anything chunky in there when spinning it, you should be just fine.

As long as there is enough to keep the gears lubed, you should be fine. Thanks for the comment!

RcHelpDotCom what about the left front wheel is not spinning whit the other 3 wheels could you answer whats the problem? love your video!!!
thankyou!
almost thought you weren't gonna add grease when you mentioned lube haha. Thanks for the video well done
Nice video. Very easy to follow!! Only difference is my slash 4x4 has sealed diffs.

great video. thanks for the tips, im gonna clean up my diff cuz it doesnt spin that freely.
Very nice video. Thank You
Hey Tony whatelse can you use if you dont have trinity bearing oil
Any local hobby shop should have some good bearing and/or bushing oil that you can get. www.Rc-Help.com
@@RcHelpDotCom thanks

Nicely Done!!!

Thanks for the info it really helps.
please help i cant reconnect the axles to the differentials and i didn't even take the differentials apart
it seems as though someone before me has put the diffs in backwards because my truck is in reverse, has this happened to anyone before. should i swap them around>?
The diffs wouldn't do that. Make sure your transmission isn't in reverse, a lot of times the servo input is flipped and reverse becomes forward.
I've replaced the rear diff on my T Maxx 3.3. The wheels spin while off the ground but when the model in on the floor it doesn't move. I have checked all grub screws on the driveshafts. If I put all left, right, front or back wheels they will spin freely on the ground but not all together. I'm thinking that it has a gearbox problem. What do you think?
I suspect your transmission is messed up.
So can u use diff oil for cars in a sealed rc diff?
Yes, but these are not sealed. So be careful with leaks.
My Diff are sealed can I still use grease instead of oil
If it is a true sealed diff, such as on a Mugen 1:8th scale buggy, then you will need to use the appropriate oil rather than grease. At least I would.

@@lokomono89 dont use wd40 on bearings.
You must have grease/oil in your diffs.
Tip: never clean one diff and not the other. One of the diff will take too much pressure and strip the inside gears.
You are correct. It creates an imbalanced load.
Thank you!
