    Default Another opinion

    I am completely anal about my XJ. Noises, and things like that simply must be tracked down. It's a 96 and had Rustys 3" full leaf kit until recently. The coils had sagged so much and it was not level so I swapped some stuff. Here's the specs now:
    Full 3" leafs with Chevy lowering shackles (they actually raise the Cherokee about 2")
    RE 3.5 coils and .75" spacer.
    Skylacker fixed LCA's.
    Track bar relocation bracket.

    I guess this stuff raised it up about an inch from where it was and leveled it out. I was really happy with how it sat afterwards. I did get it aligned. I definitely notice it handles differently now though. It seems to require a lot more corrective steering while traveling at highway speeds. I don't think it follows grooves in the road and the steering wheel does not jerk in my hands from bumps. My friends that have 8" lifts and 35-37's tell me to stop being a woos and drive it. They say if it handles differently it's just b/c it's a lifted XJ. This can't be right though. I wonder if the trackbar and draglink angles are screwy or it has something to do with the relocation bracket? I'm hearing a lot of guys say that bracket is garbage and can cause bumpsteer. I'll get a pic of my angles if it will help. I don't think I'd want to drive the thing on a long road trip right now b/c something just doesn't feel right. Thanks.

    Riv,

    Your TB and DL should be EXACTLY parallel to each other for best results. I had a relocation bracket on my 95, and got rid of it in favor of a Kevin's TB conversion, same as the RE HD model. It made the ride a lot better steering wise.

    It could also be your CA angles. If they are too steep, they transfer more impact into the body of the XJ as oppossed to the suspension of it.

    A pic of you CA and DL/TB angles would be good.

    I would toss the trackbar bracket and get a heavy duty trackbar for a lifted XJ. Like Fergie said the angles need to be exact, The more you can keep the angles to factory specs. the better and safer it will ride.

    Hey Fergie!

    I was wondering about it after finding this pic of another XJ:


    This is about what mine looks like and this guy is running the same bracket too and dealing with similar issues. I will post pics of my front end tomorrow. Thanks...both of you.

    What you need to do is to draw some lines.

    One from mount point to mount point on the TB, and one from the steering box mount to the DL/TR connection. Those two line need to be parallel, or within a few degrees.

    And ditch the bracket. Redrill the stock mount, go OAB(too much IMO), or get an HD bracket for the body side.

    CA angle pic?

    This isn't my XJ so I'll get pics of the TB/DL and CA's tomorrow. I used the bracket b/c I wanted to have the axle centered. I guess this trade off wasn't worth it. I realize the bracket should be a temporary fix until I can do it right with an adjustable TB.

    the highlighted lines show the angles that should be as close to parallel as possible.Attachment 7540

    Thanks Mike. I just can't believe that would make it so sketchy to drive. On mine, it looks like if I just ditched the bracket and used an adjustable TB (like you both said), the lines would be really close. I researched a bit and some guys (not here) were saying drop pitman arm but that would make things worse. Does your buddy just have an adjustable TB? Also...what lift is that Jeep at? Pics of mine are coming.

    Default ADDENDUM to info

    Since you guys are playing with one of the vehicles I worked on at JTE, I hope you don't mind me adding some more information on this:

    1. The statement about keeping the panhard rod (commonly called a track bar) and the draglink is absolutely correct. Keep them exactly parallel through the JOINTS (the bar itself does not matter, except in the case of bending-the more offset between the bar and the "action axis" through the joints, the greater the bending force on the bar itself). Anytime motion changes direction, the geometric intersection of the force axis of "A" and "B" (whatever components A & B are) is the actual location of the change, not the connecting bars, links, or whatever.

    2. The steeper the total angle between the axle end joints and the body end joints, relative to the horizontal wheel end to wheel end axis, the more lateral "head toss", or lateral body movement, you will have, which induces the death wobble when it phases with the bending of a high offsett in the bars themselves, as well as true bump steer in the steering geometry. In other words, the included angle between the 2 axis causes the amount of curve to the arc of the panhard rod movement (the greater swing the axle has-since it does not move straight up and down, relative to the body.

    --Sidebar comment, nice explanation Fergie. Ya done good!
