my 1993 jeep xj has death wobble at speeds ranging from about 30 to 45. i have replaced the trac bar bushin all control arm bushings and even the steering stablizer and bushings. i have come to find out that i have a bad axel(or wheel joint could that cause death wobble. also i have check the allignment and ball joints all are good, also checked tie rod ends. any help i greatly appreciated
do you have a lift? If so then your stock UC's may be the cause. Mine had serious DW and since replacing the BJ's, steering stabillizer and buying aftermarket UC and replacing the UC bushings, my DW does not exist. I sometimes even run it without my sway bar and I still dont have the DW.
sounds liike its something getting worn out, if you ran before and never had any issue, then out of no where it started acting up. just seems like something should be apparent or whatever that its broke
In my experience (doesn't say much..) that when I had a bad axle joint my xj would DW more upon braking at that speed for the reasons you said. So I replaced and it helped but it would still happen upon braking. Turned out my spindles were warn and was putting unequal pressure from the calipers to the pads and warped the rotors...wierd stuff...replaced the rotors (and such) and had a local shop recondition the spindles were the calipers seat for $30.00 a side and all was peaceful in the land. But just my experience so far. Just another thing to check. Keep us posted! Good luck.
Hope you git it figured out before your withdrawl symtoms git worse...
Not sure if the axle shaft is throwing it out somehow, anything is possible it seems. Somethings loose or out of balance. Keep us posted and good luck!
