I have a 94 grand cherokee 3" spacers amd shocks only. I used to have death wobble with stock tires when i would hit a bump doing about 50mph, found out the stearing stabilizer was missing. I poped one on and all was good. Now i bought set of 36/13.50r15 irok super swampers, with 2" spacers to make fit. Now i get death wobble on smooth payment going about 40. I check all my bushings, and made sure everything is tight. What do i do next to get it to stop cheap fixes first, because i will one day put bigger axels and all under my jeep. So i dont want to spend alot of money to just get rid of later. Just please any suggestions im a mechanic and cut weld and fabercate anything so no idea to far out there.

Thank yall.

 

Typically death wobble is caused by track bar length. Though steering stabilizer will mask the issue, it does not solve it. Many people including me don't run a steering stabilizer. Do you have an adjustable track bar? Also if you bought the 36s used I would have them balanced because if they're out of balance you will also get wobble

 

You said u have just spacers and shocks. Asuming no track bar. I would look Into buying an adjustable track bar so u can center you're axle under the jeep as its pulled slightly to the driver side right now causing wobbles aswell

I had dw in both my xjs first one was caused by worn tie rod ends sec one was cause of loose track bar.. but bad uca an lca bushings will give you the loose feeling just before dw hits. I know the for fact cause i went threw it couple times it sucks but is funny to watch every one around you freak out

 

My axle is pulled to the left a little and not causing the wobble. Not saying it wont but its more then likely a tie rod end or loose track bar

 

Definitely make sure you have track bar brackets or adjustable track bars. Also check your ball joints, replace your steering stabilizer if it's stock and looks bad. Also check your hub assemblies, control arm bushings, etc.
