Rear wheels don't move, blown diff?

Post by MShark » Sat Jun 01, 2013 10:28 am

As the topic says, my rear wheels don't move. I bought my savage new and haven't even used an entire gallon yet. Should this be covered under warranty?

I was doing figure 8 donuts when all of a sudden the truck stopped doing donuts. I took a closer look and thats when I found out that only the front wheels were working

9 times out of 10 this turns out to be a grub screw that fell out of either the cup coming out of the rear end or behind the transmission. Look real close it can be hard to see if the screw is there. My bet is that its the one at the rear diff. If one is missing pit a new one in and use blue loctite. While you are at it do all 4 to make sure they stay in place. This is real common especially on a new savage.

If it is the diff I'd be getting a hold of HPI. They should cover it. They did with mine.
They sent me new parts. the only thing is it takes a long time to get them.
If you not braking something..... your not trying hard enough!

Usually a blown diff will make noise,,(crunching,clicking,clanking,grinding)

I would agree with Leroy,,Its probably the grub screw.

remember that on newer savage its a grub shaft now,,the screw might be there,,but shaft is broken,,remove the grub screw/shaft to be sure.

A grub screw is a allen set screw, with a shaft coming off the end opposite the allen wrench place.  It acts as a pin to pin the cup to the pinion gear.

Get a few of them, at least have one extra in the box.

Is the grub screw #86094 on page 59 of the Savage X 4.6 manual?

There are 2 sizes, (or there were on older savages haven't bought a new savage in 4 or 5 years) worth getting a pack of both.
