Front-End Shudder at freeway speeds
 

I had the fluid changed out of the transfer case, tranny and both
differentials on 89 4.2l Wrangler last week. When I drove it on the
freeway for the first time since the fluid swap, I notice a shudder in
the front-end when cruising at speeds in excess of 50 miles an hour.
The shudder is not consistent. If I lay off of the accelerator, the
shudder diminishes and disappears and I can accelerate again for a
period and then the shudder returns. It is a very hard shudder, almost
shaking the steering wheel out of my hands. Can this be related to the
gear box oil changes or is this just a coincidence and if so, where
should I be looking?

Any help appreciated...

Thanks,
Ethan

Hi Ethan,
The lubrication will free up loose front joints like tie rod ends
and ball joints enough, to let an out of balance wheel and/or alignment
problem shimmy. But it won't shimmy unless the steering stabilizer shock
absorber needs replacing, pictured at:

Bill, a tire(s) enough out of balance will shimmy the front end even
with a brand new HD steering stabilizer...ask me how I know...replace
the ss only _AFTER_ everything else has been fixed.
