Vibration under driver's seat when accelerating only, and more than ~30mph and pulled front driveshaft with no change. u-joint in rear driveshaft going out or should I check something else too?
Check for a sagging transmission mount allowing the exhaust to touch the crossmember during accel
The other night when I took the front shaft out I shook the shafts by hand, kicked the crossmembers, checked all the arms on the suspension, nothing seems loose or bad. I'm going to pull the rear shaft and see if the joints feel weird.
Add motor mounts to your list of things to check.
When you pull the rear shaft, don't just look at the U-joints. Put the transfer case in 4wd and drive the car to see if the noise is gone.
also a good thing to look for. this usually makes a clunk when popping your foot off the brake in reverse though because of the direction of torque.
