18. On 5-Speed Manual Transmission Models, test drive the vehicle & shift through all gears. If it is difficult to shift into 2nd, 4th or Reverse or if the transmission jumps out of gear, the shifter may be contacting the edge of the transmission tunnel due to the transfer case drop. Examine the area & if the shifter is contacting in this area, proceed to the steps below.

1. Move the seats to full rearward position.

2. Pry up the shift boot & bezel from the floor console.

3. Remove bolts attaching the console to the floor pan. Lift the console upward & remove.

4. Remove the four (4) screws attaching the cover boot to the cover. Slide the boot upward to expose the opening in the Photo # 32 floor pan.

5. Shift the transmission into 2nd, 4th or Reverse verifying a Minimum of 1/8" Clearance between the shifter lever & the floor pan. If necessary, enlarge the opening in the floor pan with a round file. (See Photo # 32)

6. Reposition the boot clock wise to match the increased floor pan opening. Mark & drill three (3) new mounting holes. Reinstall the cover boot, console, & shift boot.

Final Clearance Check & Torque Steps:
Notes: Check Front Center Axle Disconnect (CAD) connection & on RUBICON Models: Check Front & Rear locker connections.
The Drag Link Must Be Adjusted to Center the Steering Wheel Before the Vehicle Is Driven. Failure to Do So Will Cause Computer Errors, Odd Handling Characteristics, & Poor Performance.
1. Start vehicle. Make sure there are no dash lights pertaining to suspension.
2. Jounce vehicle a couple of times. This will help suspension settle to new ride height. Cycle steering lock-to-lock & check all components for proper operation & clearances. Pay special attention to clearance between tires \ wheels, ADX Shocks & Reservoirs, control arms, brake hoses, ABS wiring, etc.
Rotate the drive shafts & check for interference at the differential yoke & Cardan joint. If necessary, lightly dress the casting(s) and \ or u-joint tabs in order to eliminate binding.

5. Driveline vibrations can be caused from the removal or addition of a hardtop which changes the vehicle's rear weight & rear height. The weight affects the rear drive shaft pinion angle. Skyjacker's adjustable eccentric upper cam-bolt kit (Part # CAM500) will eliminate such vibrations by adjusting \ rotating the rear pinion angle up or down as needed.
If already purchased, install eccentric upper cam-bolt kit using the steps below.

Cam Bolt Installation:

1. Use Skyjacker # CAM500 Eccentric Cam Bolts for Rear Upper Control Arms at OEM axle

mount brackets. Perform Steps on One Side at a Time.

arm from OEM rear axle mount

using a 15mm socket \ wrench.

Note: Only Disconnect One (1) Side

at a Time.

The OEM control arm axle mount brackets have 'knockout' alignment inserts. Use inserts as a guide & cut a slotted rectangular hole. Using a Sawzall, Dremel or other small cutting device, cut out a notch on each side of rear upper OEM axle mount bracket. (See Photo # 33)

Final Notes:
· After installation is complete, double check that all nuts & bolts are tight. Refer to the following
chart for proper torque specifications. (Note: Do not re-tighten nuts & bolts where thread lock compound was used.)
· With vehicle placed on ground, cycle steering lock to lock & inspect steering, suspension, brake
lines, front & rear drivelines, fuel lines & wiring harnesses for proper operation, tightness & adequate clearance.
· Have headlights readjusted to proper settings. · Have a qualified alignment center align vehicle to OEM specifications. · After first 100 miles, check all hardware for proper torque & periodically thereafter.
