I had to replace my rear differential due to grinding and metal shavings in the rear end. Recently had to take my truck in for repairs due to the motor mounts breaking. Discovered the front differential is also damaged with metal shavings due to grinding. The auto shop reached out to the local Chevy dealership to order the part to place. Was told the front diff is on back order due to this being a common problem.
