Re: Front end vibration... still. :(
 

I'm starting to think that's the only thing it could be. I've pulled
the front axles, but not the rear (the Dana 44 is new to me). They
look straight to me, and I've put a straight edge on them and there's
no distortion. There are no visible weld spots where a weight would
have been...

Tonight I replaced the rear brake drums. Same thing.

I'll pull the rear axles tomorrow to see if they're okay.

After that, I'm out of options, and I've got to find a Jeep friendly
mechanic in North Atlanta who will look at a lifted Jeep. The dealer's
service department won't even talk to me because of the lift.

Re: Front end vibration... still. :(
 

I checked the fan clutch tonight -- it seemed solid and tight.
Anything I should specifically be looking for?

Hi Jason,
It's got to be your tires, find someone with a set of his stock
rims and tires sitting in their garage to use, as a test. You may see
how a Dragster tire distorts at speed:

And considering every tire is hand made it's a miracle there are more
factory seconds out there. What is your speed rating, maybe you
shouldn't travel at seventy:
