IMPORTANT ALERT: GM uses a very strong thread-locking compound on all
body bolts. Use of an air assisted impact ratchet can cause damage to the
threads on factory body mount bolts and the internal nut assembly because of
this thread locking compound.
We only recommend the use of hand tools to slowly remove and reinstall body
mount bolts on all GM vehicles.
PROCEDURE:
CRITICAL INFORMATION: If during the removal process, it becomes increasingly
difficult to unscrew the body mount bolt with hand tools, tighten the bolt several
rotations to clear the thread locking compound from the threads, then reverse
direction and continue to unscrew until the body mount bolt is out. Repeat this
process as necessary on all GM body mount bolts. Use of an appropriate anti-
seize compound is highly recommended for re-installation. Tighten body mount
bolt to factory torque specifications for your particular model year.
