Hi.
I have an 05 Envoy and when backing up I have noticed a "whirring" "clicking" noise from the back end. It stops after 3 or 4 seconds. Doesn't seem to do it any other time, and even then not every time. First thoughts are fuel pump or something in the electronic AWD. Anyone else ever experience this?
Thanks

Does your truck have electronic air suspension?

Yes. Bumped into something about that on another forum as well and got me wondering if that might be it. Just got the truck recently so don't have too much experience to fall back on.
