Hey guys! New here, so I'll start out by telling you I have a 2010 Silverado, 5.3 4x4. Reg cab....... My baby. Today, noticed a squeaking noise in the rear end. It sounds like rubber moving around, but I have no idea. It happens while moving slowly in reverse, and when accelerating at higher speeds. There is no vibration or anything else..... Just a god awful sound coming from the back. Someone mentioned a CV arm to me - Just wondered what you guys thought!
