Check your driveshaft going from the transmission to the front diff.

i checked the driveshaft but that wasn't it. i also took the transmission apart and when i opened it up there were metal shavings all over. i checked all the gears and took them apart and cleaned them and put it back together. after it was put back together, i get this grinding noise when i push it. i cant figure out what it can be.

is the noise coming form the trany or the rear end. you may have took out a rear diff.

I would take a look at the rear diff.

I took the rear differential out and it looks like the bearings went out on it. Do you know if HobbyPeople sells replacement bearings for the diff and a replacement gasket, or do I just have to buy a brand new differential?

Yes .. you can get the bearings or the gears ... I'm guessing the stock rear diff went out. Is the pinion and ring gear ok? Also, it's a must to shim the diff closer to the pinion to tighten up the gear mesh other wise when under load the plastic diff housing will flex and you will chew up the teeth. I've been racing savages for a long time, and HPI released a upgrade diff kit with aluminum diff housings and spider gear shims to tighten the mesh in the diff and prevent flexing internally. I can't find the part number for this kit, but I know that you can get the parts to build one. I'll look once I get home for the part number and post it.

I'm curious as to what gear went out. That will tell a lot of what you need to do when you rebuild it. The other option is to buy a complete diff, but I would go through it and of course shim it.

Here's the diff parts sheet... this should help find the parts that failed.

I took the differential apart and the only thing that was wrong was the bearing went out. everything else was perfect. i repalced the bearing and put it back together and started it up and it runs perfect.

Thanks for helping me out.
