    OK, Check this out:

    I attacked the Jimmy this past weekend. The death wobble was starting to be a real pain in the butt Welded up some frame cracks around the steering box and added the reinforcement plate mod. Then I replaced the drag link ends that looked alittle sloppy. And to cap off I added two washers on top of each king-pin spring.

    Presto! Death wobble cured. But now the truck wanders all over the road. WTF? :confused:

    Checked the tie rod ends (the whole D60 was rebuilt about 8k miles ago), checked the spring u-bolts, tightened the spring shackles, adjusted air pressure. Hell, I even eye balled everything in the rear of the truck too. I've been chasing this all week (after work - in the perpetual rain).

    Today I check the toe (w/measuring tape) and it looks like I've got TOE-OUT! I shortened the tie rod just a little and I'll check it again (accurately) at work tomorrow.

    But how the hell did I suddenly get toe-out? :screwy: I haven't crashed into anything or even been flogging it lately (frame cracks scare me, lol). Could the washer trick (some how) alter the toe? Has anyone run into a mysterious toe change before? :crazy:

    Forgive me for ressurecting my own dead thread... but here's the latest update:

    Fixing the toe may have helped tire wear (at least that little squeal when I turn into my driveway is gone), but it didn't do anything for wandering. I've checked and rechecked the spring shackles/bushings. Well many projects later, I finally get around to doing what I should have done earlier. I removed one of the (two) washers I added to the kingpin spring. PRESTO wander gone! :doah: I also replaced the steering damper cause it was shot and certainly contributed to the death-wobble in the first place.

    Lesson Learned: Good kingpin springs and too much preload (added washers) equal steering response DRAG, which is felt as steering WANDER :thinking:

    I had the same thing happen to me :D . What size washer(thickness) did you end up leaving in because even one fender washer caused that problem for me?
