I have just returned from the Chevrolet dealer near me. They are the only ones here that works on Barvadas now.
They checked the 4wd out and told me that I had a bad right wheel speed sensor and this was causing the problem. On the rack the 4wd seems to be working. They gave me a price of $250 to fix it.

Before I go this route can anyone tell me if this could possibly be the problem?
From everything I have read on this forum and other places this should not be the problem.
Thanks in advance.
