welcome to hpisf wildchild! without seeing a pic or vid, I'm thinkin that a bit of shimming is in order https://www.hpisavageforum.com/forums/showthread.php?t=1873

i do have pics but i have to find my camera lol. it only tears up the left side bearing. and it been sidelined for about two weeks so i had to order a new diff cuz it tore up the ring gear and pig gear. and when i'm bashing and whoopin the guy next door in a straight line it floats like a caddy how can i fix that?

I have the exact same problem. I'll bust a diff. bearing after about 8-10 tanks. It's not a shimming issue. They are shimmed. I just replaced all the diff bearings on my 3 savages with 10x16x5's from Avid Bearings. After my Thanksgiving bashing session I noticed that were failed again (10 tanks). Maybe the Avid's are just cheap. I'm looking into the Boca Green seal.

yea wild, again without seeing a pic & assuming that your bulkhead isnt damaged, I'm gonna say that you need to shim your diff to get a nice, smooth mesh with your pinion & eliminate substantial side-to-side movement on your diff.

you want a minor bit of side-to-side play & I'm gonna say about .4-.5mm would be sufficient to mesh smooth but not damage.

in this pic i had to shim the diff 'opposite' the ring gear side of the diff to get the mesh i was lookin for


sorry for using the same pic in different threads, but it stinks having a diff problem, been there done that

thanks man this is my first monster truck i have mostly onroad cars but having a savage now is so much better than onroad you can really get nasty with them plus is more of a challenge to drive and race. i did check the bulk head and all looks fine no cracks could it just be dirt cuz where i live we don't get much rain and there's a ton of dust.
