Yesterday on my way home my 87 Sami developed a noise sounding like some sort of gear slippin when starting out in 1st gear and once torque is eleviated the noise subsided. Although I was nursing it quite a bit to make it home. So I did not press my luck to see how bad I could make it grind. I happened once or twice in the begining of second also but not as bad. I am looking for a place to start my search as the most likely cause. I know the bearings in my transfer case make a lil noise and I just got the rebuild kit and new gears for that. But the noise just doesn't seem like that. I am leaning towards the rear end diff but don't know how common this is with Sami's and how to diagnos without disassembling it first. Trying to keep guesswork to a mininmum. Thanx for any help someone may have.
