Vibration

[RussellL]

If you can set the jeep up on jack stands you can run it with the wheels off the ground.  That will eliminate the tires being the source of the problem.  You can also watch the drive shaft spin to see if it is bent or anything like that.

There's another possibility that hasn't been discussed. I have seen this vibration happen when the parking brake is adjusted a bit too tight or when the parking brake drum is bent/distorted. Try backing off the star wheels in the parking brake and see if that helps. Also check the drum for runout.

THE TACK WELD ON THE DUST CAP ASSEMBLY COULD MAKE A VIBRATION AT CERTAIN SPEEDS.

Great thoughts by all...as always.  

Gun, I did have the tires balanced.  I read enough posts here about the Wobble and other handling issues.  Guys at the tire shop thought I was nuts, but I had them do it anyway.  

I like the idea of getting it off the ground and seeing if the vibration is caused by the tires or something else.  This will help me as I also intend on exploring the hand brake issues that Rocketeer mentioned.  That drum is quite heavy.  If it's not balanced or is rubbing on the shoes it could be my issue.  I'll take a peek tomorrow...if my wife doesn't string me up for disappearing into the garage again.
