Bad vibration I have a 93 sierra 1500 ext cab 2wd. It had a 4.3 v6 in it with the 700r tranny. I put a 350 4 bolt main and a turbo 400 tranny. thing was working fine till I noticed a howling noise. I found out it was coming from the carrier bearing.

check uni's, check tail shaft alignment and also for any signs of damage on the shaft, start here.
