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.
