Truck is a 2000 S-10 ZR2.
I've had this for a little while now and it recently started getting
worse. It's somewhat intermittant, and now it seems to happen at all
speeds, but it used to be specific speeds.
I recently rotated the tires and that didn't change it at all, it
still vibrates and it still doesn't vibrate the steering wheel (tells
me the front-end is good and the tires are not the problem,
ball-joints are only 5 months old). I just did a pry-test on the rear
u-joints, no play there, I used the biggest screwdriver we have, which
is pretty big, maybe as big as a small pry-bar. I didn't pull the
rear discs off to check for a dragging e-brake pad, maybe I need to,
though I use the e-brake all the time.
Is it possible my DS is out of balance? I didn't notice any missing
weights on it, but ya never know. This truck has a one-piece aluminum
rear driveshaft, so it's not the center support bearing. Now that I
think back, this seemed to have started shortly after the ball-joint
work, which was done at my local dealer, they're close by, closer than
any mom-n-pop shop I actually trust. I need to check the rear axle
fluid, that may be tomorrow. Is it possible the CV's on the front
axle would cause this and not shake the steering wheel?
I know I have some torsion-bar support links that are worn, the ones
on the cross-bar the bars are tensioned on, but that's another clunk
I plan to be towing this summer, would like to get this resolved
before then. Need to install a tranny cooler before then also, and
get the tranny serviced.
TIA for any help, I know you guys will probably come through with the
answer as I've seen it happen before, and helped make it happen a few
