I'm getting a shake/vibration anytime I go 20-30mph. after 30 it goes away. if I let off the throttle when I'm going 20-30 mph it goes away. just had a front end alignment and tie-rods, ball joints, control arms, and bushings are all good.

also, my steering wheel is now angled to the left (as if I'm slightly turning left) when I'm straight. How do I fix this? Thanks!

 

As for the steering wheel, they probably did that during the alignment. Take it back to them and have them correct it. They need to loosen both the left and right adjuster sleeves on the tie-rod-ends. They need to lengthen the left one and shorten the right one. (Or vice versa.)

 

or do it yourself. it can be done in about 5 minutes.

as for the shake it sounds like your about to get death wobble, check your track bar it could be loose too

 

dumb question: which one is the track bar?

 

That's the bar that mounts to the axle on one end and to a bracket on the frame on the other end.

 

If you have the "New" kind of steel wheels, they are made to trap mud and snow and they will certainly cause the steering wheel to shake.

 

i had the same problem crawl under your jeep grab your rear drive shaft near the u joints if it moves that is your problem, has it gotten worse or been about the same

 

had a simiular problem but only when i hit a dip in the road at that speed, turned out the hub bearings came apart and the only thing that held everything together was the axle shaft nut. check your hubs.

 

checked the rear DS and it's good. Just replaced the u-joints in it about 8 months ago but I figured I'd check any way. Haven't checked the trac bar - good call on that one. When I got the alignment they said I did have some play in my wheel bearings so it could be that. Sucks that I gotta replace the whole hub just to fix the bearings.

need to find and fix the problem, not cover it up.

 

Already have a Rough Country stabilizer- brand new - so I know it's not that. Either way, that could simply cover up something worse so I'm tearing into it this weekend, hoping to find the problem.

 

if your wheel bearings have play that could certainly set off a shake/vibration. especially the speeds youre talking about it happening at. my 93 did the same thing, replaced the bearings and it was fine. also dw will occur at a higher speed, around 40-60 or if you hit a bump or if youre turning a corner somewhere around those speeds. definately wheel bearings if youre sure everything else is tight and not worn/damaged.
