Ford 8.8 bent shaft or bent axle

Okay whats the easiest way to tell if I have a bent shaft or bent axle housing? got some rubbing from the rear axle. 88XJ with 4.5 lift drop brackets 99 Ford 8.8 rear and new brakes/rotors all the way round. No Trauma that I am aware of. spring perches were supposedly welded on with small frequent welds/cooling to prevent distortion.

TIA John

If the tire apears to wobble while it spins then it's the shaft, if the tire runs pretty true then it will be the housing.

use an angle finder to see if flange is perpendicular to shaft.

Are you serious?You need to put a dial indicator on the flange and check for run-out.

I wasn't going to assume that everyone had a dial indicator laying around, or was in the market to buy one.

Re: Ford 8.8 bent shaft or bent axle

Point being,if you could measure it with an angle finder or framing square,its bent for sure and you could see it with your eyes,no tools needed!
