    Shift fork in the T/C is broken if the lights on the dash still work without flashing all at once and there is no SERVICE 4WD message. Had one two weeks ago. It was going to cost more to put in a used one (with a warranty) than to put in a reman from GM. The rebuild cost was going to be about 80% of the replacement so the customer got a new one.

    I bet he will need a front diff like GG said.
    Gas Guzzler Prolly has a diff with 3.73 gears.

    If I busted a diff open it would never work again. I can however unbolt one and bolt in another.
