Hello everyone, I joined the community here in hopes of solving my current problem. I recently got a 7.5 inch Rough Country lift kit installed on my 2007 Yukon SLT 4WD. The problem is while I am driving and let go off the gas. The very front middle bottom of the truck makes a very loud rubbing sound. It only makes the sound when I let off the gas... if I step on the gas the sound stops temporarily but returns as soon as I let off the gas. this sound does not happen while I set my truck on 2WD. So essentially, it makes a rubbing sound ONLY when the truck is on “Auto” or “4WD” the truck never did this before the lift. The shop that installed my lift kit reviewed my truck tightened everything back but the problem persisted. Any ideas? Any advice is appreciated! Thank you, Gerardo H.
