I have a 99 WJ that now shakes uncontrollably at 45-55 MPH, i took it to a local shop and they told me it was the steering stabilizer shock, which didnt seem right, and it wasnt, im pretty sure its one of the tie rod ends, and on the way back to the shop after the first trip the driver side caliper completely locked up, any info or suggestions? anything helps because i have to drive 4 hours home tonight hopefully! thank you

has good info about death wobble and what causes it. Mine was a combo of a needed alignment and worn out tie rod end on my drag link.

 

it ended up being a warped rotor and a bad caliper, this is the second time ive had warped rotors on this jeep, and i just had to replace the brake booster two weeks ago

 

you might want to look into gettin some better quality rotors. i got napa ultra premium-they dont warp as easily as others

 

Hand torquing the lug nuts with a torque wrench will help keep the rotors from warping.
