Note: For optimum rear driveline performance we recommend a slip yoke eliminator kit and CV drive shaft be used with this lift (see slip yoke vibration in “troubleshooting” before proceeding).
1 Block rear wheels of vehicle.
2 Raise front of vehicle and support frame with jack stands.
3 Remove front wheels.
4 Remove front shocks.
5 Remove axle end of front track bar.
6 Support axle with jack stands.
7 Remove u-bolts & spring plates.
8 Remove leaf springs.
9 Install new front brake line extensions.
10 Lightly grease front main spring eye bushings. Main spring eyes use the 9/16” id steel sleeves at double military wrap end.
11 Install leaf springs into vehicle with double military wrapped end at the frame (see photo 1). The center pins may come with spacers installed for use w/ floating type degree shims. Be sure pins do not bottom out on axle tube whether using shims or not- remove spacers if needed. Slightly snug bolts. DO NOT fully tighten the spring eye or shackle bolts at this time. Bolts will be tightened to spec once the vehicle is on the ground (step 18).
12 (See photo 2 for typical installation of steps 12-14). Install new u-bolts with old spring plates. Torque u-bolts to 65-80 ft/lbs, or u-bolt specs if supplied.
13 Use tie rod removal tool to remove drag link at pitman arm. Use a puller to remove stock pitman arm. Install new drop pitman arm and stock drag link
14 Install longer front shocks.
15 Install sway bar disconnects.
16 Install front tires.
17 Lower front of vehicle.
18 Torque spring eye and shackle bolts to factory specs.
19 Install axle end of front track bar with new bracket. Small end of new bracket will fit into slot under factory mount (see photo 3). Drill out old mounting hole to ½” and attach bracket with supplied bolt. Attach track bar to top hole with factory bolt.
-REAR AXLE-
20 Block front wheels of vehicle.
21 Raise rear of vehicle and support frame with jack stands.
22 Remove rear wheels.
23 Support rear axle with jack stands.
24 Remove shocks.
25 Remove rear track bar. This will not be reused.
26 Remove u-bolts & spring plates.
27 Remove stock rear leaf springs.
28 Remove factory rear brake hose and replace with new stainless line.
29 Lightly grease and install main spring eye bushings. Main spring eyes use the 9/16” id steel sleeves at double military wrap end.
30 Install new rear leaf springs into vehicle with double military wrap end at the frame (ref. photo 1). The center pins may come with spacers installed for use w/ floating type degree shims. Be sure pins do not bottom out on axle tube whether using shims or not- remove spacers as required. If using steel Rubicon MFG’s shims, remove the spacers and replace with the shims. These steel shims will require reaming to 3/8” for 3/8” pins.
31 If using, insert 4* wide shim between spring and spring pad on axle. Thicker end of shim should be at front of vehicle (pinion points up).
32 Slightly snug bolts. DO NOT fully tighten the spring eye or shackle bolts at this time. Bolts will be tightened to spec once the vehicle is on the ground (step 41).
33 Install new u-bolts with old spring plates. Torque u-bolts to 65-80 ft/lbs, or u-bolt specs if supplied.
34 Install longer rear shocks.
35 If using, install transfer case drop kit by supporting one side of transfer case with floor jack. Remove hardware from one side of cross member. Install spacers and new hardware. Tighten to 55 ft/lbs. Repeat on opposite side.
36 Lower axle so it is at full droop. Rotate the rear drive shaft to insure the yokes do not bind. If yokes bind and shims are installed properly, a slip yoke eliminator and CV drive shaft are likely required.
37 Lower rear of vehicle to ground.
38 Bleed brake system. Inspect all brake hoses and lines for leaks, kinks or damage.
39 Grease all zerk fittings on new bushings.
40 Lengthen drag link to center steering wheel.
41 Recheck all bolts - use factory torque specs if not given. Recheck after 50 miles and then after every off road excursion.
42 Reminder: Do not reinstall the rear track bar; it will not be reused.
