Default wheels hop when hitting any bump on highway.

What do i need to look into. When i hit a bump on the highway it feels like my wheels want to turn the opposite way i am driving but then steadies out pn smooth ground. Questions and info just let me know thanks.

Is it only at highway speeds? It might be death wobble. Search that and see if your symptoms match up

I sometimes get the feeling when I am turning. If I am turning and hit a bump, or if I was at a high speed and hit a bump, it would feel as though the rear end would want to slip out from under me. I replaced my shocks and now that feeling has been brought down A LOT.

Bad shocks, unless its death wobble.

Then anything in the front ends is suspect.

Had that on my old 1990, replaced the steering damper and stabilizer bar.
Damper is 30$ and the bar is 100$.

does the steering wheel feel tight? Pretty easy to get used to a sloppy steering wheel as things wear. Could be worn steering parts or steering box.

Steering is anything but tight what steering parts might it be.

I think you might have a bad shock when was the last time they were replaced?

Agree w/ above. Get the rig off the ground & check for any play in the wheel bearings, ball joints, tie rods, drag link etc. (bushings as well). Possible steering damper? OR if you are going into a turn & you hit a bump, your suspension will unload (esp. w/ worn shocks), camber changes or centrifugal motion pulls you in the opposite direction. Is it sprung stiff?

check all parts as chitown suggested, balljoints rotate alittle but should not be loose (up/down, left/right, front/back).

If all the moving parts are confirmed tight put the jeep back on the ground and while you look underneath, have someone rock the steering wheel back and forth only the distance of the freeplay. If the pitman arm does not move with the steering wheel then the play is in the steering box. I've never heard of someone successfully adjusting the freeplay from a worn steering box. If it's worn out it's time for a new steering box.

How tough is it to replace a steering box? I have a lot of slop in mine and ran your test and it was infact the box. I checked out Dukie's right up on his but he didn't go into too much detail. And if any one knows off hand. How much would a replacement box be? durango or xj. If you know off the top of your head.

When I priced out a Durango box it was like $160.

Have you tried the adjuster on the box to tighten it up?
