Re: Front End Shake
 

Well, suspension lifts and big tires put a 'whole' lot more stress on
things so wear parts fast.

You could easily be looking at an out of balance problem which is
showing you a worn part early.

Rotating the tires tells you fast if it is a balance issue.

Even if it is just balance, I would be inspecting the tie rod ends and
steering components like bushings to see if wear does come into play.

If the steering geometry was off, I would have expected trouble from day
one...

You might want to look into getting a steering stabilizer.
Just do a little research on them, check out the explination at this

A steering stabilizer is a simple shock absorber, nothing else. It is
there to mellow out any impacts the tires see when off roading or when
tracking on road ruts and to prevent harmonic vibrations from setting up
from slightly worn parts.

If you take it off and the front end shakes, you need to 'fix'
something. You won't get shakes unless something is worn or broken.

I recently found out that my CJ7 with it's 33" mud tires has never had
one on in the ten years or so I have owned it! It has a rod and an
empty tube sitting there where a shock should be.

I had bad shakes and wanders when I first got my Jeep. Once I 'fixed'
everything that needed it, it has run perfect since.

This could be a agrevating cause but the basic problem is a instabilty
in the front end that when it is given a reason to shake it can go
crazy. If the front end was stabile a balance problem would provide
likely more than a shimmy. I have seen front ends shake so bad that
you think something is going to break of fall off. This instabilty is
want lets it "run away" sometimes.
