With the floor jack under the rear axle, attach your coil spring compressor onto the new rear coil spring and compress the coil 1”-2”. Set the upper coil insulator on top of the coil spring and position the top of the coil into the frame pocket. Push the bottom of the coil spring onto the new spacer and raise the floor jack under the axle to hold the coil spring in position. Remove the coil spring compressors. Repeat this with the opposite coil spring. USE CAUTION WHEN WORKING WITH COIL SPRING COMPRESSORS, THEY CAN BE UNDER EXTREME LOAD. SEE FIGURES 42-44

54. Reinstall the shocks onto the lower axle mounts using FT20673BK Rear Shock Bracket Torque to 100 ft-lbs. SEE FIGURE 45

55. Raise the floor jack supporting the rear axle and slide the upper mount of the track bar into the track bar bracket. Align the track bar with the hole and reinstall the factory bolt. Torque to 95 lbs.

56. Install tires and wheels and torque lug nuts to wheel manufacturer’s specifications. Turn front tires left to right and check for appropriate tire clearance. Note - Some oversized tires may require trimming of the front bumper & valance.

57. Check front end alignment and set to factory specifications. Readjust headlights.

58. Recheck all bolts for proper torque.

59. Recheck brake hoses, ABS wires and suspension parts for proper tire clearance while turning tires fully left to right.

60. Check the fluid in the front and rear differential and fill if needed with factory specification differential oil. Note - some differentials may expel fluid after filling and driving. This can be normal in resetting the fluid level with the new position of the differential/s.

61. Install Driver Warning Decal. Complete product registration card and mail to Fabtech in order to receive future safety and technical bulletins on this suspension.

Vehicles that will receive oversized tires should check ball joints and all steering components every 2500-5000 miles for wear and replace as required.

RETORQUE ALL NUTS, BOLTS AND LUGS AFTER 50 MILES AND PERIODICALLY THEREAFTER.
