I can tell ya what, I have the same problem with my V6/4.3L auto 2wd 1998 Blazer, as well.
It's certainly not in the front end, that's tight as anything. It's somewhere in the center to rear of the vehicle.
Yeah, same here. Neutral doesn't change the vibration. (So that would seem to count out trans/torque converter slippage that I originally thought of) I've been pondering u-joints, the rear axle or axle bearings, or rear yoke, on mine.
One thing I've noticed is it actually vibrates LESS if I have more weight in the back.
Any thoughts, people? It seems to be a bit of a chronic problem for our aging Blazers.
