Installation Steps - LUND 26510010 Instrucciones De Instalación

Installation Steps

Start the installation under the driver side of the vehicle and remove the front, center and rear body mount bolts. Do not remove bushings.
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.
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 fac-

Hang the driver side front, center and rear Mounting Brackets from
the body mounts in the order pictured above using the factory hex
bolts, (Figure 1). Do not tighten hardware at this time.
