I'm confused on a "front-end" shimmy that wouldn't be felt in the
steering wheel. Can you help me out here? If the wheel is steady while
the front end is shimmying, I would tend to think out-of-round tires or
a shock that isn't doing it's job. Are you having to endure wire wheels?

I've also had shimmy problems but they were felt entirely through the
wheel. A combination of brand new, balanced tires, and a careful
alignment has pretty much fixed the problem. Toe at zero, camber
negative a degree. Camber matching. If you can't go negative camber, I'd
go with a little more toe -- maybe 3/32s. If you can get more negative
camber, I'd try 0 or sligthly positive toe.

If you want a little shimmy, my sure-fire method was to have too many of
those little tiny shims in the front hubs between the outer bearing and
the internal spacer. Must be how they got their name. I found the
correct thickness of shims to measure exacly 0.0000000 inches.

full service gas station; was driving a brand new pickup truck; was
frequenting discoteques; had considerable expertise drinking and
driving; and partook in as many meaningless and unprotected sexual

unapproachable and another in a red box sprite who wasn't.
