Raise the vehicle and support it
with properly weight rated safety
stands, ramps, or a commercial hoist.
Follow the manufacturer’s safety
precautions. Take care to balance the
vehicle to prevent it from slipping or
falling. When using ramps, be sure the

the topsides; place the transmission in
park; set the parking brake and place
blocks behind the rear wheels.
CAUTION: Do Not Work Under Any
Vehicle Supported Only By A Jack.
Severe Injury May Result.

require the use of a torch and/
or saw. Proper safety equipment
should be used. Failure to use
proper safety equipment may
result in severe injury.

Remove the factory tailpipe from

hangers using a large screw-driver or
pry bar.
Note: Lubricating the rubber hangers
with WD-40 or similar lubricant will
ease removal of the hanger pins.

Loosen and move the spare-tire
to the rear of the vehicle and center
between the dual tailpipes. Securely

rear fender such that the tip position is
aesthetically pleasing.
