Wrangler rearend

My 1990 wrangler rearend has shifted to the left about a half inch. How do I get it back in the center it's eating up u joints. I can see what appears to be a sway bar with a big bolt and nut I can see shiny metal from where this bolt moved. Should I lessen it up and try to slide rearend back to this point and tighten the nut back down.

Did you lift it, then this happened? The bar that you see is the track bar. When lifted, it will pull the axle sideways because it is binding. If it were my jeep, I would take it off. When I lifted mine, the track bars did the same. I took them off and it straightened out, and rides nicer.

I'm not sure what would be causing it then. I know people here have way more knowledge than I do, hopefully they will chime in. I'd still consider taking the track bars off, as they don't really help on YJ's, and you will get a softer ride. Just leave the sway bar on if its a daily driver.

ok you found the problem but didn't elaborate... i'll still bite, aside from the obvious problem of the rear end shifting over slightly, explain to me how this minor change was "eating up u joints"

1/2 difference wouldn't eat up the joints. They go through much more range than that up and down with the axle articulating. If you're running trackbars, I'd remove them. They only bind between the axle, suspension, and frame.

Are the u joints greasable? Did you grease them?

Well I can see the driveshaft isn't in line with the rearend I can see it tailing toward the drivers side so I'm assuming this is why the u joint isn't lasting. They are not greased joints. The next ones will be

It's a factory track bar. So your saying remove it? Someone also told me if I remove it that I would get a better ride. I do drive it daily. But also use it for hunting during deer season. So it goes off road some

Removing the trac bar (front and back) will give you a better ride on the road and better flex off road. I removed both on my YJ when I bought it and never looked back.

I removed my track bars and love it. It's about as smooth a a leaf sprung jeep will get.

That wont damage a ujoint... You have other issues if the offset is that minimal causing ujoint problems
