    Mystery Slack/Play - Wheel hub? CV? Ball Joints? (2008 Yukon Denali)

    I've got a mystery issue involving play in the front end. If the vehicle is on the ground and you grab the top of the front wheels (on both sides) and pull, you feel play and get and feel a 'clunk' like you would with a bad wheel hub and possibly a ball joint. Jack up the front end by the frame...

    Door/warning chime/turn signal click no longer working - 2008 Yukon Denali

    This is annoying - my warning chimes and the click sound for the blinkers are no longer working. I've check the speakers in the driver's side, had the module checked, checked the settings in the DIC, BCM, radio, wiring harnesses, etc., I couldn't find anything and the stealership (not a typo)...

    Bizarre rear passenger window issue (I'll bet no one has had this happen) 2008 Yukon Denali

    08 Yukon Denali rear "Apsirator" buzzing. Really obnoxious.

    The aspirator in the headliner (the one in the rear, not the one over the driver's seat) is buzzing like a bee in a plastic cup. It's really annoying. The front aspirator was easy to replace then it was buzzing, but for the sake of my sanity, I can find no way to access and replace the rear...
