Rear wheel death wobble??

Didn't think I would ever have such a thing, but I do! Under 55 is no problem, over 55, and I hit a bump, instant whole truck vibration. No steering wheel input, and its definitely coming from the rear. Hit another bump, and its fixed.

After pulling a stupid load, occasionally there was a clunk, or shift from a dead stop. Just like a transmission mount, or even motor mount going out. They all checked out, and I have been driving it unloaded for about 2 months now since. I have not experienced that shift without pulling a load since.

Today going home, I hit a pothole on the highway, and it sounded like I was crossing the hash marks to wake up drivers, and the whole truck shook. I pulled over, didnt see anything, and carried on. Hit another bump in the road, and it came right back.

I'm thinking centering pin, but I dont see any obvious signs of the axle moving. Thoughts?

This is what may have started all this crap...the wedge weighs in at 9k, and the middle jeep is a fat pig with a full cage, and 60's. I was not happy to pull it, but we were in a bind, and only had 50 miles to travel.

I would do a thorough check of your rear springs, shackles, and u-bolts for anything loose or broken.

Then check your driveline u-joints and carrier bearing for excessive play.

That's exactly what I did. I found no smoking gun with it on the stands. I didnt check the carrier bearing, or the u-joints though. I didnt think they could cause a bump induced vibration. After I was checking it over, I noticed the truck leaked about a cup or so of oil in 30 minutes from the bellhousing. The intake also has a pool of oil in it. I decided to park it and borrow my buddies truck.

I had what seems the exact same issue! Sounded like hitting rumble strips on the side of the highway. I thought it was my transfer case. Well it wasnt. It was the front needle bearings inside my hub assembly that ride on the axle shaft. Greased them up and the sound never came back again.
May be a ton of work breaking the front down to inspect but very easy to repair and I didnt replace the entire assembly.
