YJ help bump steer
I'm the new owner of a 95 YJ with a 4" lift. My previous jeep exp was with a 90 XJ that I mess dearly. The problem I'm having with the YJ is scary bump steer. I've never had a lifted jeep before so I need help on how to fix this. It get damn scary at 40-45mph. This is going to be my winter only truck so off roading isn't that important to me. Not crashing on the way to work is. I got the truck for a good price and it has my fav engine and trans combo 4.0 and a 5 speed like my XJ had. The tires are also like new 33 bfgs. I would like to know if maybe the lift was not done right or maybe the lack of a front sway bar is causing my problems. I'll post some pics in the hopes that that will help.
First off, remove the trac bar. The rig will ride and flex a whole bunch better. The angle on the drag link does not look bad, you may get some mild bumpsteer (when the springs compress the drag link going up causes the steering to dart to the right) Check out all the front end parts thoroughly, tie rod ends, ball joints and wheel bearings.
Smoke em if you got em!

it doesn't feel like it's wandering, problems only start when I go over a bump or dip in the road at 40+ mph. Is removing the trackbar safe? I've been browsing the net and it seams that 1/2 say go for it and 1/2 say don't. I've also seen pics of other yj front ends. They have sway bars and end links, do I need these? Did all YJ's come with them?
As far as sway bars are concerned, yes it came with one. Do you need them? That is the 50/50 split right there. I didn't run sways on my last YJ and was absolutely fine. Others say they don't like the ride without them.
The sway bar (or lack there of) won't cause bumpsteer though. Just a more "boaty" feel, or body roll while turning or high speed, sharp maneuvers.
Check and make sure that your shackles are properly torqued and that the bushings are good. While you're at it, check all your ball joints and tie rod ends.
wheel jerks and jeep darts to side, probably. mine does that and i have the same angle on the steering linkage. i know an alignment is part of my problem though and i have not recentered the steering arm on the gearbox from the lift so once i get my springs swapped around to be right, recenter the arm, and get an alignment, then i will look into other things if i still have bump steer.
I don't feel like working on anything at this time so i sold my yj.
