Repeat this procedure with body mounts

2 3 4

and

and Extended Radiator Bumper on the

PASSENGER SIDE of vehicle.

Insert the last remaining Body Puck (A) at body
mount

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

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.
