Rear Tire Lean

[grimlock97]

I have been searching for a while to get an answer for this without posting, I have an M998 and the previous owner (The Army Most likely) rode the tire until the outside was bald and the tire is worthless, I know there are shims above the rear control arm, the tire leans drastically from the top out, I have already replaced the tire, can I simply remove all the shims behind the control arm to take the lean out? Is there anything wrong with doing this? The shims hold the control arm about an inch or more off the frame right now. Is there anything else that I need to look at first? Thanks for the help up front.

You need a 4 wheel alignment.
They will check for bent & or damaged parts.

Can a typical auto shop do it, or do I need to take it to a truck shop? This thing leans so far the inside of the tire is barely touching ground.

I'd pull all the shims out of the upper control arm. If the shims were not the same on both sides, leave the odd shim there.

Thanks, I'll give that a try, worst case I guess I have to put all the shims back in!

Many hmmwv's are set for a load and if the truck is not at rated load, then drastic outside tire wear occurs. Some have removed the shims at the top a-arm brackets against the frame rail. Some have taken it to a truck shop to do it. If shims are removed, then a complete alignment is required. Since you may do that, plan on replacing all tie rod ends and ball joints.

Thanks again for the info

Any good alignment shop should be able to do an alignment on it. If they wonder about specs just align it to H1 specs as the suspension is pretty much the same and that would give it a setup for street driving to not wear the tires.

It probably has heavy duty springs for a shelter carrier or ambulance, or slant back.
Another option is to put lighter duty springs, change all ball joints, and shocks while in there.

I saw this one out in the wild. My ntc truck is not nearly that bad.
