Default XJ Death Wobble

It started when i swapped the 33s for 34s at 30 or so she would wobble something fierce so i went to rustys and got the dual steering stabilizer. no improvement. then i put the 33s back on there it helped but now she wobbles really really bad at 45 50. I know that beast really shouldnt hit the freeway but for me to get her to gore or heck up to st marys i need to calm her down. . . checked everything and all is tight nothing broke during her throwing a fit i think an alignment is up next is there anything else?. any ideas?

There are about a dozen or so things that could cause death wobble.

Step one: Sit in front of your XJ and observe all the moving parts as someone else saws the wheel left to right about a 1/4 turn each direction.
Your looking for any play in the steering box, pitman arm, TRE's, drag link, tie rod, ball joints, etc. This will show things that can't be seen by just grabbing and trying to wiggling things to see if they are tight.

If you've done that and have found nothing:
Step two: Allignment

OBTW, the steering sabilizer thing....put a dual unit on the JK....actually feels less effective than the single unit...but it's on.

concur with Gunny's assessment....that's how we found the problem on Arics rig a few years ago, sitting in front of it at Charlies deli watching all the linkage.

Outstanding advice Gunny, I think I'll head down and give him a hand. I may not know what I'm doing (mudpit), but maybe we can get lucky.

Is it really DW or just a bad shimmy? Did you get the tires balanced when you swapped? Bad balance will make a really aggressive shimmy...

both sets of tires have been balanced. . . I am thinking there is something broke, loose, destroyed or out of alignment. . .
