Strut mounts or strut bearings are often service with the strut assembly, and when they fail they can make a squeaking noise while turning or a metallic clunk noise when going over bumps. If your 2011 GMC Sierra 2500 HD is noisier than usual on bumpy roads or under braking, you may need new strut mounts.
