Default TJ 3" lift now death wobble

My 2004 tj drove great but I had to have a lift. Being a cheap ass I bought used coils and rear track bar locator installed them, lowered the transfer case, spaced the shocks, for th front track bar I drilled a new hole 5/8" from the original. Worked great for a week or so. Then deathwobble, so I drilled out the bushing and hole for a larger bolt was a little better, so I replaced the track bar bushing with a poly bushing, but I still have death wobble.

Im thinking my next step should be an adjustable track bar, but give me some suggestions.

get under it. have someone steer it left to right and back many times. look for play anywhere. something is loose. also get and alignment, changing the springs and not the arms is gonna mess with angles. re-balance the tires.

What joejeep said. Many people like to claim steering stabilizer when in fact the steering stabilizer is nothing more than a band aid for steering issues. Check torque specifications on all your front end bolts with a torque wrench. Impact or Breaker bar tight is too tight, if you are worried about bolts loosening use loc tite, but tighten the bolts to factory torque specification and get an alignment.

Ok guess im looking for factory specs cause I definatly overtightened everything, and I knew an alignment is a requirement so that is moved to the top of my to do list.

get some caster cam bolts or make your own. set your toe to 1/16-1/8" in and max your caster with those slots on the lower axle mount.

three times my trac bar failed at the upper connection, it was very noticable when some one shucks the steering back and forth while you look under neith.

Sounds like the exact same thing I ran into. 3" springs, then death wobble. It is caused by some compliant steering parts, but the reduction in caster from the 3" lift is what made it a problem. Caster adjustment first.

unless you buy caster cams before saturday, they will just set your toe because thats all that is adjustable on a TJ. Won't fix anything.

moog calls them cam bolts.

What he said, I had the same issue after I installed the lift and it turned out my new front adj track bar and the bracket were slightly loose which cauaed a wobble. Make sure everything is super tight. Have a friend move the wheel back and forth an look, you will find your problem

Must be luck and loose tolerances if you need caster shims,or not.I have 2.5 rc springs and 2.25 terraflex boost blocks and my junk drives great with a tape measure allighnment.I drive it daily on the highway and have 65,000 miles on my km2s.
I have had death wobble twice and both times it was a junk track bar.And there was that time I rebeaded a tire with a bunch of snow in it,but that doesnt count.
I recomend adjustable arms or cams,but I have had no problems without them.
