99 Bravada all wheel drive shudder
I have a 99 bravada with approx 60,000 miles. Bought off lease at 39,000....from that time it has always shuddered quite a lot when turning sharply in parking lot, etc. as if front differential is partially locked all the time. This is my first (and last) auto all wheel drive, so I dont know how much is normal. VERY ANNOYING in parking lots especially.
Even in a straight line green light situation, slight shudder is transmitted through steering wheel indicating to me that those front wheels are recieving power - when they really shouldnt.
Please help! I understand that these units employ a viscous coupling in the center diff - could this be my source of problem? is it adjustable?

AH YES WHAT NEED TO DO IS REPLACE THE TRANSFER CASE FLUID WITH WHAT IS CALLED AUTO-TRAC II. GM PART #12378508.
YOU'LL NEED TWO QUARTS. THERE IS A SLIP/STICK CONDITION GOING ON INSIDE THAT CLUTCH PACK.
