    I have a 2001 wrangler with 3" suspension lift and 2" body lift. Driving at highway speeds it feels as if the wheels are being turned slightly left and right. Feels like a boat rocking. I have to continually stay on top of steering. Kind of darty driving straight. Tierods and ball joints all tight. New double stabilizer. New bushings and adjustable control arms. Caster is 86 degrees and toe 1/8 in.
    Any ideas on fixing this issue?
    Thanks in advance
    Mike

    Have you ever replaced your ball joints? I know you said they are tight, but. . . I feel the same about the tierods. Have you added a steering stabilizer? With 5in of lift I bet you are running 35s. If you are running the recommended air pressure on the sidewall of the tire you probably have too much air making you squirrelly. Jeeps don't weigh very much requiring less air in the tire. I run 37x14.50x15 on 15x10 wheels and I like to run 12lbs. If your are running 35s or even 33s Id run about 20lbs. How about the control arm bushings? When you go big even slight ware causes big changes, so I would go back to basics and replace anything you haven't already replaced starting with, tierod ends, ball joints, control arm bushings, steering stabilizer. . . I would consider even less toe in if possible. I run mine at zero to less than a 16th of toe. Bigger tires accentuate the toe in. Almost forgot Steering gear box. Hope this helps.

    Thanks for the info. I'll try the air pressure and tierods ends hopefully that will help

    Peter has good advice...

    However, with a lift of that size, if you have not taken the proper steps to accommodate the changes in steering geometry, that can throw everything off and cause the exact issue you describe. Do you have a Drop Pitman Arm and/or a longer Drag Link? These can be called for with 5" of lift.

    Just a thought... :)

    I'm not sure about the pitman arm or drag link. We had this jeep lifted in 2002 and not sure if drag link was changed. I believe the pitman arm is stock. We never really drove the jeep much until last year. I've been replacing parts and driveability has gotten much better. I'm trying to get the little bugs out of it. I have a. Ew pitman arm ordered. I'll post my results after installation. Thanks for the info

    A dropped pitman arm will take care of any "Bump steer". You feel bump steer most when you go through a big dip or series of dips in the road and the steering wheel moves side to side on its own with each dip.

    Replace the drag link I have an 05 and my Bud had an 01. We both had similar issue and we both replaced the drag link, as previously stated, the drag link should have a new hole to bolt into, or a longer drag link. Most of the time the drag link will have a new mounting hole drilled in just about 1.5" below the original hole.
    Also, just like P above, iron 33" at 25 psi
