hey guys, I have been searching the net for some answers and came across this site... looks like a great resource for these trucks, I'm hoping someone can help me with this problem.
I have a 1990 Sierra 1500 single cab longbed truck... for a while it was making a grinding noise going from 2hi to 4hi... and then it would slip in and out of 4wd. Now it doesn't go into 4wd at all. I can shift it into 4 LOW but I only get RWD LOW. My mechanic figures the chain is stretched on the t-case but I'm hoping to get a second opinion.
any ideas?
