Question: Front Differential and Transfer case

Is it possible for a front differential to loose all it's oil without noticing a leak and then run dry for an extended period of time without symptoms, i.e. noise?

Can a failed diff cause the transfer case to fail, or can a failed transfer case cause the diff to fail?

Any experience getting an extended warranty to cover the damage?

To answer your second question: it depends on what parts failed and what problems were potentially caused.

If the drivetrain is covered under the warranty, it will depend on the specifics of the warranty wording. If the first answer you hear is no, pursuing the issue up the GM chain of command can be necessary. Don't expect the first answer to be yes, and the link above has a good example of someone using the Better Business Bureau and small claims court.

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
