TRAXXAS - XMAXX FRONT & REAR DIFFERENTIAL SHIM FIX - HOW TO FIX THE GRINDING GEAR PROBLEM - XLX2

[@birddog435]

Great tip! I’ve been bashing my XMaxx hard and always enjoy anything that helps parts last a bit longer!

[@edgargomez2207]

Awesome! Thank you for watching. I will be making an updated Diff shim video in the near future. 🤘

[@georgewilson4614]

Definitely a good video man! Thanks for information and getting to the point! 👏

[@edgargomez2207]

Thank you sir! I will be uploading a updated video, after testing that shim theory I've learned a lot and will be sharing real soon. Thanks for watching ✌

I think this is just the answer I need on my slash 4by 4.. Great info...

[@edgargomez2207]

Awesome! Happy to hear its helpful.

[@Rckid28]

Naw it’s just the soft gears traxxas calls metal lol

[@edgargomez2207]

​@@Rckid28 Yea the metal Traxxas uses for the gears is soft but with shims + pressure + heat + grease = Long lasting Diff gears 👍

[@Rckid28]

@@edgargomez2207 that’s way to much work, gpm spiral cut gears for the win, and you have way too much grease in your diffs, your poor motor has to work so hard

[@edgargomez2207]

@@Rckid28 Just simply not worth the price and cant beat the Traxxas Price on stock gears that can be fixed by installing 2 shims and some grease. Sure the motor will work hard during the brake in period. That's why you run the truck off the ground, no tires for a few minutes. All i know is that i beat the hell outa my truck and drive line with no issues with this trick. 🤷‍♂️

Super informative video. Thank you bro

[@edgargomez2207]

Happy to hear that! Hope it was helpful. I will be posting another updated video of some better idea i came up with for better Diff mesh setup and different shim ideas.

[@eastermister1]

What part number are these shims you are using

[@romeoraduu]

Good video...it's better to put shims in the front also?

[@edgargomez2207]

yea i shim both front and rear. Seems to work really well for me. Thanks for Watching ✌

Gotta replace that roll! Smart man lol

[@ronniezhou5276]

I see you pull out the rear diff input gear with a plier, what about front input gear? Can you still pull it out?

[@edgargomez2207]

Yes you can also pull the front pinion gear with a plier or a magnet.

[@jamielevey896]

axial ax31269 are the shims you want for the pinion. perfect fit and are steel

[@edgargomez2207]

Thank you for the suggestion. Any type of metal shim will wear the plastic housing down and wont provide any cushion under load or impact. That's why I use the nylon shims that come stock in the front/rear diff housings.

[@jamielevey896]

@@edgargomez2207 the metal shim rides right on the bearing race and on the pinion back. It touches no plastic. I just like the tighter cleaner tolerance.

[@edgargomez2207]

@@jamielevey896 Yes you are correct. I thought you also put the shim on the ring gear as well. So basically metal shim on the pinion and the nylon on the ring gear. OK, Ill give it a try. Thank you ✌

@@edgargomez2207 Sounds like a great idea! I'll try it too 👍

[@juiceman8873]

Part number for the shims ? And the aluminum housing that you replaced from plastic to aluminum , not the hot racing cover

[@edgargomez2207]

The shims are already inside the stock diff housings. The aluminum ones I used are the same part as the stock center diff housing.

Is this the xmaxx 8s or 6??????

[@edgargomez2207]

This Xmaxx is 8S

[@travis4man]

That shim you have on the pinion isn’t doing anything but tearing up your housing. It needs to be between the bearing and the pinion or it’s pointless...

[@edgargomez2207]

Yes you are 90% correct sir...However the shim did not tear up the housing. I have Updated the Idea and will be posting a video correcting my mistake. I found that using copper shims that need to be fitted are the best solution. Its a whole prosses but so far its been worth the Time and effort into making the perfect size shim for YOUR application.

[@adebisi1094]

Xmax should have had machined ring and pinion.

[@edgargomez2207]

Agree 100%

[@sixteenornumber]

I have mixed opinions on how to lubricate the differentials . According to Traxxas, "Use a light coating of wheel bearing grease (from an auto parts store) on the metal gear teeth.". Light grease will fling off. When referencing oil viscosity charts, and calculating the velocity of the diff gears, they spin way too fast to use grease and should instead use oil which is going to leak out everywhere. Packing grease will reduce performance and increase heat. I have a Milwaukie angle girder that spins at high RPMs and comes from the factory with packed grease similar to the truck in this video. Here is a video showing grease being flung off the gear. kzbin.info/www/bejne/oGHMhJJ5abGdf6c

[@Wuzzzzup87]

Are you suggesting to use liquid grease like in your angle grinder video?
