Bent D30 Axle Housing...anyone else?

I found a hidden hole in a grassy trail a while back, which nearly removed my front axle for me. Yeah, ouch. Fortunately, I was able to drive it out and home. I repaired the mangled bracket and replaced a control arm, but am still realizing the other damage as I have time to look into it. Also bent the track bar.

Anyways, I need to fix it, so 2 questions:

1. Can a bent housing be straightened? The passenger side only.
2. What sort of damage can result from using it as-is? ...inside the differential, hub bearing?

Nice signature, few greater truths have ever been told.

If you have to ditch the axle, consider a hp D30 from a cherokee.

Thanks. I'm a bit of a fundamentalist. A God-fearing, USA-loving, gun-toting, right-wing fundamentalist.


Anyways, I think I'll be going for a junkyard replacement to keep the cost down if it comes to that.

Ahhh, one of those guys.

Me too

I've never heard of anyone re-straightening an axle, but I surely wouldn't want a re-straightened axle on my Jeep when I'm 150 miles away in the middle of a forest!

Axle housings are straightened all the time. That said, like mentioned, an upgrade to the HP30 wouldn't be a bad idea (though it'll cost more than straightening your current axle, new gears, bearings and setup).

You really need to go to a factory that makes axle shafts from scratch. After they heat treat them, the flanges have so much wobble to them that not one would ever be useable, that is until they put them in a press and straighten them out.

BTW- in order to re-straighten a housing, it has to have been straightened at least once already.

I wouldn't want a restraightened axle shaft either. I'm not even sure I want a restraightened housing. I'm only referring to the axle housing here...specifically the passenger side axle tube. I am assuming my shafts are ok, since the Jeep drives about the same as before, but is that even possible? Using a straight-edge, the pass. side axle tube is clearly curved up. I suppose I just need to open the diff, pull the axles and inspect. I'm about to start looking for a replacement, but just want to know how much damage it would do to drive it this way in the mean time. In case I end up with an empty housing, I don't want to trash the inners in this one.

For the record, you are already driving on straightened axleshafts front and rear. But, the easiest way to find out if you are damaging anything is to look at the shaft where it exits the housing inside the knuckle. If it's not rubbing right there, it will be fine.

I've taken a lot of front ends apart from salvage yards and only one was bent enough from a wreck that I couldn't easily pull the shafts. That one clearly showed the axles rubbing on one side of the tube where it exited the housing.

Thanks for the info! Much appreciated. Looking quickly, I didn't see any rubbing at the outside, but I'll give'r a good inspection soon.
