I have a whining noise on acceleration when my transfer case switch is on auto. When I move it to 2H is does not happen. Any thoughts on what this may be? Thanks! This is on a 2007 Silverado Z71 LTZ with 6.0 Liter VMax motor. 46,000 Miles.

  I never liked the choppiness of AFM (or DFM) in my '15 and '20 Silverados and IMO it's worth disabling just for the driving experience alone. I wonder what the actual failure rate of AFM/DFM is.

  I have a 2" lift, so the equivalent of the factory trail boss height, and it has been on the truck for approximately 165,000 miles. I don't believe the lift to have had any significant adverse affects on the ball joint. The socket was dry of grease and warbled out over extended use, but the ball/bolt itself wasn't broken, stripped, bent, or anything. It just pulled out when the UCA socket bore wore enough for the ball to slip out.

  It use to be pretty common for me to add a Super Charger. The only way I would chance it today would be dealer install with a warranty. I only have experience with Ford. They are doing well so far.
