So I've been noticing a vibration taking off from a stop up to maybe 15mph only when I have weight in the truck and only when I am turning. Got under the truck near the rear diff and couldn't get any movement. Went 1/2 way up the drive shaft and I get some movement but my xfer case also moves up and down. Should that be? 122k on her so I'll change the front u-joint but should I also change a mount?
I have a 2" leveling kit and a 1" block in the rear.
Also what is overkill for a u-joint? Make and model?
Thanks
