Offset rear axle? Is it possible or is sometihing bent?
« on: March 16, 2010, 07:20:51 PM »
Well I'm hoping and praying that I don't have a bent frame.  I bought my Jeep having been in a rear collision.  I thought there was no frame damage and I really still don't think there is.  I bought it from my mom so I know how the accident happened.  It was hit in the rear a taller truck and pushed in the tailgate, spare tire, and left rear behind the license plate.  The rear bumper has one small dent in the left rear didn't even colapse it all the way.  Any all that to say with the stock tires and a 2"BB it drove fine even up to 70+.  I put 31's on it and found out the right rear rubs the upper spring mount and the left rear is @2-3 inches clear.  I really really don't think the frame is bent.  Is it possible for the track bar or bent things that link the axle to the body??  HELP please about to rub a whole in the tire!!! :'(

I would suspect it to be a Jeep TJ? from your description.

What more than likely has happened is the bb lift was installed without track bar brackets. In the rear, you should have installed a riser bracket off the axle. The bracket basically recenters the rear axle under the frame. In the front, the bracket on the axle is redrilled 3/4" over to bring the axle more centered under the frame. The track bar is to maintain the axle under the frame since it is a specific length. Any height difference between the axle and frame pushes or pulls the axle off center from the frame from the track bar.

So I doubt the frame is bent and the track bar bracket was not installed. Rather than look for a riser bracket that wasn't installed, look to install an adjustable front and rear track bars.

Wouldn't it rub on the left side instead of the right though.  The way I think about it with the rear track bar being attached to the body on the right it would move the axle to the right when lifted causing the left side to rub.  Mine rubs on the right side.  I am determined to figure this out.  Thanks for the help.  Any other ideas or expand on this one.  It is a TJ

What you're seeing is the stacking of tolerances.  It's common to get one side rubbing but the other side doesn't.  If you're really worried then take a tape measure out and start measuring from the frame to the axle at different points.  If you find the axle is offset then start with the track bar and go from there.  With a 2" lift you're already starting to affect the alignment so you might want to check that as well.

You are correct, as the jeep is lifted the rear axle should shift towards the right, thus rubbing on the left side coil bucket.  You have some serious issues since the rear axle appears to be offset quite a bit despite having a spacer lift that should have offset it the opposite direction.

Can you post a pic of the jeep taken from behind?

You can host them on Photobucket, Picasa or any other site that allows hot linking.  You can also attach the photo to your post and have it hosted on the forum.

is the rubber bushing at the axle end of the track bar good? also check and see if it's not bent.

there is about 1/2'' or so of adjustment where at the trackbar bracket on the axle, check and see if you can loosen that bolt and move the axle to the right, but it seems to be offset more than you can adjust
