I've been messing with a front end shimmy on my '77 FJ-40 for some time now. It has 4" SUA lift springs, JTO 2.25" anti-invert shackles, and 35" MT Radial Claws on 10" Fake beadlock rims. All bolts are tight and torqued. Tie rod ends are good. I've added a new stock stabilizer, plus an aftermarket Rancho. I have even rebuilt the center arm. I need to recheck is tire balance - my concern is that they are not dynamically in balance, due to the fake beadlock outer rim, or the ties are out of round. The shimmy starts at about 50-55mph - never gets into the "death wobble" though. Could it be as simple as dynamic balance? My dad thinks my 4 degree shims aren't enough, and the caster is off, but it drives straight and steers correctly in corners. The driver's front wheel is leaking something, and it's bearings may be a little worn. It wasn't as noticeable with the hardtop and doors on, but I run it now without. Anyone?
