Repeat this procedure with body mounts
2 3 4

and
6
and Extended Radiator Bumper on the
PASSENGER SIDE of vehicle.
Insert the last remaining Body Puck (A) at body
mount
1
located beneath the grill.
Apply medium strength thread locking compound
to the last remaining 7/16” x 4” Bolt (D) and insert
with a 7/16” Flat Washer (E) into body mount posi-
tion
1
.
Using a torque wrench, tighten all 1/2” and 7/16”
Bolts (B and D) to 30-35 ft-lbs.
Note: Use care when tightening bolts to avoid crush-
ing factory rubber body mounts.
5. SECURE STEEL BRAKE LINE
Locate the grill support that is welded to the round
cross member at front of chassis.
Drill two 3/16” holes through top of grill support
located approximately 3/4” from edge of support
and directly in front of the grill.
Insert the two plastic brake line clips into the 3/16”
holes, and then snap the steel brake line into plas-
tic clips.
6. MODIFY RADIATOR
Locate the four plastic fan shroud mounting holes
on the steel radiator bracket.
Measure exactly 1” below the factory mounting
holes and mark the location with a center punch.
Drill a new 7/32” hole through all four center
punched marks.
Test fit the fan shroud to the radiator by aligning
with the new mounting holes.
Check for interference between the fan shroud and
radiator hoses, fan blades, or any other objects. If
necessary, trim the fan shroud until it completely
clears any interferences.
Secure the fan shroud to the steel radiator bracket
with the original four mounting bolts.
Note: The original bolts may be used to tap the new
mounting holes. However, it will be easier to install the
bolts if the mounting holes are pre-tapped with a 1/4”
NF tap.
7. CHECK T-CASE OPERATION
Check operation of the shift lever to ensure the
transfer case fully engages all ranges.
Note: If necessary, adjust linkage between shift lever
and bell crank. If interference is experienced, it may
be necessary to trim the floor to provide sufficient
shift lever clearance.
8. POST-INSTALLATION
Check all mounting hardware to ensure it has been
correctly installed and tightened to factory torque
specifications.
Check torque specifications for all mounting hard-
ware after driving vehicle 50 miles, and after first
time off-road.
Maintenance
Check all torque specifications as part of regular vehicle
maintenance schedule.
