Background: 97 TJ, 3" lift, 35" tires, 4.56 gears, 113K. About 2 months ago my front end started go wander side to side. Replaced steering box, pump, and stabilizer (needed upgrades anyway) but still have problem. Rod ends are good. Upper control arm bushings are on order, so is an adjustable trac bar. Anybody have similar problems?
The lift is a Rubicon Express 3" super flex (RE7003). I didn't have the money for upper arms or the adjustable trac bar at the time (August 2000). I just got the trac bar today and am in the process of upgrading to poly bushings for the arms. When I did the lift I gained @5" in the back and @4.5" up front. The gap between the tires and fenderwell were @10" with 31's. I was told that the springs would break in after 1500 miles. 12000 miles later no change. I commute 100 miles a day back and forth to work 5 days a week.
You didn't mention alignment (I may have missed it)...what you describe is characteristic of toe out (or too little toe in). Any biasing of the steering wheel one way or the other sends the beast in that direction...you're always correcting. Caster could be a factor ..but that usually shows up as a shimmy that develops at speed and won't go away until you come to a stop....but too little caster would make for too easy steering and you would lose the self aligning characteristic of positive caster...so I guess that could be it as well.
Now that I've quit smoking my doctor informs me that I'll die in much better health!!!
