1994 Jeep yj slightly bent axle

I get a slight wobble in my Jeep at around 60 mph. I researched and noticed a very slight rear passenger axle bend enough to notice by looking a tire when driving at low speed / wife driving. Did the whole jack up remove tire to confirm. Do you think this is the problem? I’m leaning toward replacing just need confirmation before I move forward. Any help greatly appreciated. 94 yj with Dana 35

A little confused on how you determined -

Why not swap wheel I would suspect a bent wheel first...

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.

I had the tires balanced and they saw nothing. I jacked up rear end and took video of the axle shaft spinning with no tire/rim and the right rear has a slight wobble to it. Left side perfect. Do you think the slightly bent axle shaft would translate into a larger wobble at high speed or is there something else I should look for?

I can't say for sure but I'd think with the high strength steel in an axle, bending it without breaking it would be a heck of a thing.

You can drain the diff, remove the center pin in the carrier, and pull the C clip out in the center and the whole axle should come out. It's not a real hard job and I'd do that before buying a new axle.

It is quite possible to bend an axle tube. I've seen a few. This would probably cause the axle shaft to act wonky.

I may just replace the axle and see if that does it.

Usually good Dana 35's can be had on Craigslist for around $100-150. Might be cheaper than buying just an axle. Is your rear axle original to the vehicle? Early YJ rear axle are non-c-clip and the parts are not interchangeable with the later c-clip rears.

Those are signs of a bent axle shaft near the flange. I've seen my share of that. Not that it's 100% guaranteed - but highly suspect.

The bend is often caused during a heavy side load or accident where the rear axle gets smacked. Not uncommon at all.

Just ordered new axle shaft for $109 and wheel studs. It looks like I have the Dana 35 with 27 spline c-clip. Not a bad deal from roughcountry free shipping. Looks to be fairly easy to change out just time consuming. Needed to change rear diff fluid anyways. I will report back if this fixes the 60 mph shake I have going on.

Axle shafts can and do bend, I've seen a bent shaft from a Crown Vic 8.8 do the same. Hope the new shaft fixes your issues.
