TJ vibrations

I consistantly get vibrations when driveing my TJ @~55mph - 75mph. I figured that it had to be somewhere on the drive line as it is not RPM dependant and how is is consistantly in the same speed range.

I have balanced my wheels/tires
I have checked all of my u joints/drive shafts for any sort of play
:repair:
(figured that I would start easy)

... and still the vibrations continue

forgot to mention it's a 2001 stock TJ w/ manual transmision

any sugestions?
Thanks.

how about your track bar? that would cause vibes if the TRE was bad or the bushings on the end. if it moves even 1/32 of an inch you could get the vibes.

thanks for the reply.
I'll have to check it out.

Track bar, make sure it's tight, we even got a bad new one that caused problems but replaced it with a RE adjustable.
