Scary wobble after turning...what is it?

After I take any type of hard right turn, my wheels seem to not be able to pick a direction, when I turn my wheel to the right, it seems like the steering has to catch up, and then over compensate by steering way to far to the right or the left, depending on what direction I turn the wheel, Usually this happens to me after applying a little bit of power into a right turn. after I stop, usually it stops too.

I just replaced the tie rod, and the ball joints are all fine.

Is this the "Death Wobble" I have been hearing about in the later models?

HELP!!!!

Nope. "Death Wobble" is on 2005+ models and anyway, doesn't really match your symptom description. You just have failed steering/suspension components. However the power steering on a diesel is different than my gasser so I won't speculate.

I just recently experienced this. It deteriorated over a couple months to the point I was afraid to drive the truck. Take a GOOD look at your front U-joints. Took me a while to find the problem because they didn't fail in the way I thought they would. They had no play, but they were intermittently binding. Taking a turn rolls their position slightly, even if the front hubs are out, which is why the problem recurrs after a turn.

so this even happens when the hubs are not locked? because I know my U joints are somewhat old, but they are still okay. I need to wait for work to slow down to replace them.

Do you think this is the problem?

I didn't believe it either at first. Neither did the guys at the garage I go to.

Park the truck with the wheels turned hard, hubs out and the transfer case in 2wd. You should be able to reach under and spin the front axle at each U-joint. You might be able to feel the bind as the joint rolls over.

At least it is worth spraying some penetrating oil on them to lube them up a bit.

Did you have the front end aligned afterward? The toe-in may not be correct.

I did, and it seemed fine for a while, but they may have done it wrong, I had Mr. Tire do it for me.

Yep, it just happened again. Felt like the Wheels were going in different directions. WTF? It just kept going from side to side with the slightest movement of the wheel

Probably a combination of worn out trac bar bushings and sloppy steering box. You can replace the bushings and you can also tighten the steering gear if it's not too worn.

I'm willing to bet it's a combination of binding (bad) u-joints and the needle bearings locking to the axle stub (or the hubs are staying locked).

With regards to adjusting the steering box, my '99 behaved like yours AFTER I tightened up the steering box. Maybe the shop you took it to tightened it up too much. Just a thought.

Yes. My truck was doing this and I found one binding u-joint. Turn wheels slightly, and with hubs unlocked and t-case in 2wd try to spin u-joints by hand. You will see which one it is because it won't turn.

U-joints go bad. Even greaseable ones. and they don't usually get sloppy like driveshafts, they lock up. And cause exactly what you are noticing. I'd check those out before anything else.

Do the 4X4's have an idler arm? Sounds like what a 4X2 does when the idler arm bushings are bad. Any up and down play by hand is bad. Just as a possibility.
