    Default Jeep wandering

    OK, so my Jeep has had death wobble issues for months. It's finally wobble free..... but it wanders all over the road above 50mph. It grabs any groove or angle in the road and takes off in it. The steering wheel doesn't feel like it wants to return to center after a right turn, but it's fine after a left turn.
    I'm going in for an alignment in the morning, I'm really hoping that's the issue, but with my luck it's not.
    What else could I be looking at if it's not the alignment.
    All steering joints are good.
    Ball joints, unit bearings and axle shaft u joints were just replaced about 2 weeks ago, so I doubt those are the issue.
    Steering box maybe?

    My CJ was doing that until I adjusted the steering box. See what the shop says though, as your model is quite different from mine.

    That was one of my 1st thoughts, and I'll find out tomorrow when I see the read out... My last alignment was about 6 months ago and the castor was somewhere between 5.5-6* which should be good for 33" tires. I did just install the new ball joints, could that have changed the castor?

    If your old ones had slop in them, it likely wasn't a good reading.

    what tires are you running? Bias or radial?

    OK... alignments done.
    Before specs:

    Caster
    L 3.0* R 3.0*
    Toe
    L .03* R .08*
    Camber
    L -.7* R -.6*
    Thrust angle
    .06*

    After
    Toe
    L .14* R .11*
    Rest is the same

    I didn't get it out on the highway to test above 60mph yet, but it drives fine below 55mph.
    My caster is obviously off and I need to move it back to 5.5* or so. The alignment tech mentioned that even with the caster being low, since they were both the same at 3*, I shouldn't notice it wandering it all. BS?
    Also, I can see what the degrees are for toe in, but how does that relate to measurement? is .30* of toe in equivalent to 1/16th of an inch?

    Everybody keeps bringing up caster. Once you start lifting there is only two ways to adjust caster and still keep you driveline at the proper angle. You can install adjustable ball joints or cut the inner c from the axle and rotate and re-weld.

    I have never worried about the cast. I considerate more on toe and making sure the axles are square. If you run adjustable arms you can get a skateboard effect which will cause wandering. Check the cam washers on the lower front axle and make sure the have the same location. Also check every bolt to make sure there is no lose hdwr. This may take several checks before they stabilize. I've had hdwr take 4-6 time before they finally stopped loosening up. This includes steering. This is all just part of the fun of having a lifted vehicle.
