So for as long as I've owned my Jeep I've had problems with it pulling to the left. Especially under acceleration. The new lift went on and it decreased the pull slightly... But now it's back and as strong as ever. I have to turn the wheel 15 or 20 degrees to the right to get it to run straight now. Not only is it annoying, but it can be potentially dangerous as it makes me way more unstable on the freeway.
Two things to check... First of all, could it be that because I have a dropped pitman arm it is causing the steering to be out of whack? I wasn't aware that this torque steer was a symptom of the wrong pitman arm, I'm just spitballing.
Secondly... I am going to check tonight to see if my front axle is not centered under the rig. It is possible that because I re-used the old track bar from the 6 inch lift that I'm not centered. Thus causing the pull? Anybody else have any fixes?? I've looked at about 7 threads and all of them just tell me to adjust caster... That ain't the issue. Neither are my tires as I balance them more often than I really should.
Also considered extending the lower control arm on the driver's side about 1/8" to compensate for the pull. The steering as I envision it is designed to pull a little and my mechanic friend has told me repeatedly that I should just live with the pull... This is unacceptable to me, so I think that extending the lower control arm would help. And thoughts as to why this would be bad?? Uneven tire wear possible?
Its the drop pitman arm. Your angles are not correct between the track bar and the the drag link. I just did the Fat bobs track bar relocation bracket on my jeep and it dropped it down just a tiny bit to center the axle under the jeep. Just that little bit of angle change is giving me similar symptoms. I will bet if you got a stock pitman arm on there you wouldnt feel the pull anymore. It will also give you bump steer. When you hit a nice dip in the road while driving at a good speed it probably pulls the jeep in the opposite direction slightly.
Recommended fixes are a stock pitman arm, or if you want to get crazy I have seen systems to adjust the angle of the track bar by putting in a bracket that has multiple mounting points on the drivers side.
Yes I have noticed bumpsteer, though it decreased with the new lift and I've lived with it, I always thought that it had something to do with the pitman. Any ideas where to pick up a cheap stock pitman? I haven't even searched so I'm sure I could find the answer to my own question in about 10 seconds...
KSL and Craigs are both good ideas! Also... I think I pulled the trigger on a new rear bumper today! Found a Savvy aluminum for sale used. We'll see if he's willing to wait until Friday when I get paid. If so, I'll be able to finally get rid of the Smitty stuff for good!
Lots of little things going on this last weekend. First... Got me a new Savvy rear bumper! It was a pretty good deal used, with only a thousand miles the ad said. Since I already have a potential buyer for my old tire carrier/bumper combo I decided to pull the trigger.
Finally fixed my rear spring issue. They were so bowed that I couldn't fit any bumpstops into them. Grabbed some Ballistic Fab brackets for $40 and a friend helped me weld them on. Now I've got Teraflex bumpstops on the way to go in tomorrow night. Leaving for Moab Wednesday morning so hopefully everything is done in time. I'm sure it will work out.
Oh and I also adjusted my anti-rock because of the lost lift height. The links were contacting my grill just barely and bent a little bit of the sheet metal. Nothing major, not even noticeable. But it was still nice to fix. Jeep rides like a dream with the new spring pads in the rear, and the coilovers in the front dialed in! Couldn't be more pleased.
