WARNING! GM uses thread-locking compound on all factory body mount bolts. Removal using an air assisted impact or ratchet will damage the body mount bolt threads and the internal nut assembly.

We only recommend using hand tools to slowly remove and reinstall body mount bolts on all GM vehicles.

IMPORTANT! If during the body mount bolt removal process, it becomes increasingly difficult to unscrew the bolt with hand tools, tighten the bolt several rotations to clear the thread-locking compound from the threads, then reverse the direction and continue to unscrew the bolt until it is out. Repeat this process as necessary on all of the body mount bolts. Use of an appropriate anti-seize compound is highly recommended for re-installation. Tighten the body mount bolts to factory torque specifications for your particular model year.

NOTE: The parts kit may include additional fastener that will not be used for this application.
