Fellow EFers I call on you once again for some help with my '94. I have a terrible vibration between the speeds of 65 and 75 mph. I've been using the truck daily and have been driving it on the highway a good bit so I'd love to get this fixed as it's hugely annoying. The vibration comes through what seems to be the body, never the steering wheel. Shifter shows no signs of movement and only normal vibrations.
Things I've done so far:
U joints new 8k miles ago. Them seem solid, attempted to measure with a micrometer and everything seems to be centered.
Tires rebalance (ProComp muds) - all was good there. Still had vibration. Rotated tires numerous time; never a vibration in the steering.
Purchased new tires on Thursday, smaller snow tires. No dice there.
I have it jacked up right now with the tires off the ground. Took it up to 75 and it was smooth sailing.
I think at this point I can rule out the driveshaft? Second set of tires with the same issue? Beyond this I don't know what else to do. I've seen the TSB out there to add the fifth shock but that just seems to mask the overall problem. I'm worrying about u joints and bearings being devoured by this vibration.
The truck is lifted 2 inches with shackles and leafs in the back. I vaguely remember this not being an issue with the 235/75 tires that I had on it before the big tires.
