    Need a little help diagnosing DW

    Hey gang!

    Here's the situation, the vehicle (my kid's):

    2000 XJ, 4.0L auto.
    4-1/2" lift (various suppliers)
    SYE with a front DS in the rear. (no vibes at all)
    Replaced the front axle assembly with 1996 XJ high pinion.
    Have replaced all front end bushings, ball joints, unit bearings.
    Checked and adjusted toe-in and caster. Both in spec.
    Track bar and drag link are in awesome parallelism. No bump steer.

    Jeep drives great! Except when you occasionally hit a bump. Vehicle starts to wobble (not every time, which really perplexes me), not full blown, stain your drawers, DW. but enough to make you slow down to about 20-25mph. It then goes away.

    He is riding on stock Rubicon wheels and tires with hub-centric 1.5" spacers/adapters to get him to 5 on 5". They have seen quite a bit of abuse. DT has tried to balance them numerous times.

    He had an extended conversation with Bishop at 4WS. Those two came to the conclusion that the next step is to swap out the wheels and tires and see if that takes care of it.

    My question is: Does anybody out there have a set of low milage/low abuse JK tires/wheels that we can test with? Would only need for a short time.

    Would appreciate the help.........Thanks!!!!

    What is your toe set at? I've always had good luck with 1/8" toe in but a few years ago I was in the same boat with my TJ. went to 1/8 out and DW was gone. Drove this way for 2 years without issue. it's a 15 min swap. Try it out.

    Adam, Yah, it's at 1/8". Caster @ 5.0 degrees. Tried 1/16" and it was a bit flighty.........

    It is a DD right now due to a blown head gasket on his '97 Civic.

    I can probably help you out with a set of wheels and tires to test with.

    You will bring another bottle of BrewDog, right?

    Does he still have the stock rubber bushings in the tracbar? Bolt hole wobbled out?

    Nah. It is a Rough Country Adjustable Track Bar, The newer design, much beefier. And we replaced the bushings with poly ones. There also is a Track bar drop bracket with a stiffener going over to the other frame rail.
    Track bar mount on the axle side was drilled out to 12mm. So now it's able to be torqued to 125 ft/lbs.

    Nate. The boy didn't get over to my place until late last night. I'll have him text you today.

    Any progress? After trying everything else I ended up with heims on both ends of my tracbar.

    I'm not an XJ person, so I'll ask a dumb question. Does it have a track bar in the rear?

    I know it seems odd, but we fought the same symptoms on a TJ and it turned out to be worn connections on the rear track bar.

    Nope. XJ's have leafs. This one has RE 3.5" with 1" angled lift blocks to align pinion angle.
