Hey all, first post. I have a 1990 Jeep MJ I've done a LOT of work to over the years. Rebuilt 4.0 engine, lifted 3 inches, adjustable track bar, adjustable lower control arms, new damper, new ball joints (all), newish 32" tires. Balanced and aligned, twice because I can't figure this problem out: I still have front end shake after years. Used to be death wobble, but since replacing all the suspension compontents other threads have suggested (joints, arms, bars) it's since reduced. I get vibration between 50 and 55, and it likes to travel in the lane even slower than that. I'm thinking it's the caster, which a lot of people say should be unaffected at a 3" lift at stock 4.2°. Mine is sitting at 6.4°. My next thought is unaligned driveshaft pinions, since the lift pulled the t-case higher than the axle, but not much further. I've read that can cause shake and oscillations. Any help is appreciated. I do all my own work, and am knowledgable enough to fix what's broken, but some things I still need a hand with.
