Yj Death Wobble - Just Bad Stearing Stabilizer?
I've got a '93 YJ with a case of death wobble. Happens at about 30-35 mph and is always initialized by rough roads. I've got a 4" RC lift and 33" tires.
I jacked it up and looked real close at all the components. Couldn't find play in tie rod ends, couldn't find play in track bar, couldn't find play in steering box, all U-bolt nuts were tight. When jacked up I couldn't find any play in the tires when I try to wiggle the top and bottom (this suggests to me that my ball joints and unit bearings are at least not the problem). I did notice that I could easily move the tires in the steering rotation direction BUT the rotation moved through the whole system, steering both tires, moving my pitman arm, and moving up the steering shaft. I couldn't find any independent play between any of the components. I have manual steering.
This suggests to me that my only problem is a shot steering stabilizer. It's dang old and seems to be covered in oil. Everywhere I read people say that fixing the stabilizer only masks other problems, but I swear everything else looks perfectly tight. Am I missing something?
