Sorry HI, but the front diff was not replaced, just the seal. In addition, you didn't have the lapping compound problem, or the dealer did the repair incorrectly. With lapping compound, the entire diff housing needs to be replaced, not just the ring/pinion gear.
This is your complete service history, and I don't know of any dealer that would not submit a claim for a front diff replacement.
I do have to say, you had some problems with the radio, can I ask what the problems were?
Also, have to ask about the front crossmember.
They covered that under warranty? That sounds like that Hummer dealer did you a good turn. Usually body parts like that are not replaced under warranty since not much can happen to them from a warranty standpoint.
Here's the information on the rear axle lapping compound problem, and it states to replace the entire rear diff due to the contamination. "
Remove the axle cover pan and inspect for black discolored fluid. The fluid may show sand particles. Closely inspect the inner diameter of the ring gear for clumps of a black sandy residue. This residue is lapping compound that was not sufficiently cleaned from the axle during the manufacturing process. If these conditions are found, the complete axle assembly should be replaced, because all moving parts of the axle will be affected by the lapping compound residue.
Important Note: The lapping compound issue will not be present on vehicles built after August 10, 2005. Rear axle noise conditions on vehicles built after this date should be diagnosed and repaired as needed using procedures found in SI.
