Has anyone ever had a rear axle housing straightened? If so how did you do it and how well did it turn out?

I've got a stock style housing that got tweaked in the last accident and was wondering if I could straighten it - it's probably out 2-3* or so.

the axle or axle tube? If it is just the tube there are plans in the toolbox how to build your own straightner. If its the axle I'd throw it away and buy new.

OK - it's the axle TUBE - the axle was tweaked also and I'm getting rid of it - I had some spare axles, but not the housing (tube) part.

Looked at the axle straightener - one question I had was how to tell if it's actually straight? Do you place the framer's square across the face and see if the hubs are parallel? (like settting toe on an alignment)

on a floater type rear end take the housing out of the car and bolt the rims on. set the rims on jack stands and spin the housing. as you are turning the housing watch the rim on the side that is bent and it will move in and out. straighten the tube till you can spin the housing and the rim does not move in or out. you can use a tape measure between the two rims to check your work.

mod15r - sometimes the easy things are the best... that makes a lot of sense - I'll try that!

Just make sure the rims you are using are straight!

if your tubes are bent ewhere they are pressed into the centre housing its quite easy, if you have access to a lathe long enough to fit your rear end in, or if you have a machine shop near by.

machine a "dummy" shaft up that fits where one wheel bearing race will go and grab the other end (dummy shaft) in the chuck and then use a "live" pipe centre or large centre in the tail stock to hold the other end. now use your dial indicator to measure the run out on each side of the centre section to find your high spot, mark it, and then put it in a press and give it a little tweak, then recheck in the lathe.
might take a couple of shots but you can get the tubes very true. i've done it several times. hopefully that makes sense.
