FRONT SUSPENSION INSTRUCTIONS:

  1. Disconnect the negative terminal on the battery. With the vehicle on level ground set the emergency brake and block the rear tires. Jack up the front end of the truck and support the frame rails with jack stands. NEVER WORK UNDER AN UNSUPPORTED VEHICLE! Remove the front tires.

  2. Locate the torsion bar adjusting cams and threaded bolts. Measure exposed threads of torsion bar adjusting bolts and record for reinstallation. Mark torsion bars indicating driver and passenger. Using a torsion bar removal tool unload the torsion bars and remove the crossmember and bars. Retain the hardware for reinstallation. NOTE – Do not attempt to unload or remove torsion bars without the proper torsion bar tool. Torsion bars are under extreme spring load.

  3. Remove the sway bar link ends from the sway bar and lower control arm. Retain links and bushings fro reinstallation.

  4. Remove the stock shocks and discard.

  5. Remove the stock lower rubber bump stops from the frame and retain.

  6. Remove front factory differential skid plate and splash shield and discard. Retain hardware for front crossmember installation.

  7. Disconnect the tie rod ends from the steering knuckle by striking the knuckle to dislodge the tie rod end. Use care not to damage the tie rod end when removing. SEE PHOTO BELOW.FABTECH K1030DL 8 Inch Performance Suspension System - fig

  8. Remove the brake hose bracket from the top of the steering knuckle. Unplug the ABS brake connection from the frame and control arm. Remove the caliper from the rotor and place above the upper control arm during this portion of the installation.

  9. Remove brake rotor from the steering knuckle. Remove axle nut, washer and the 4 hub bolts on backside of knuckle. Remove bearing hub assembly including O- ring from knuckle. Retain parts and hardware for reinstallation.

  10. Remove the upper and lower ball joint nuts. Disconnect the upper and lower ball joints from the steering knuckle by striking the knuckle with a large hammer next to each ball joint on the knuckle to dislodge the ball joints. Use care not to hit the ball joints when removing. Retain nuts and discard knuckle. SEE PHOTO BELOWFABTECH K1030DL 8 Inch Performance Suspension System - fig 1

  11. Disconnect CV axles from differential housing and remove axle assembly.

  12. Remove the lower control arms from the frame and retain the arms and hardware for reinstallation.

The Limited Lifetime Warranty excludes the following Fabtech items; bushings, bump stops, ball joints, tie rod ends, limiting straps, cross shafts, heim joints. These parts are  subject to wear and are not considered defective when worn. They are warranted for 60 days from the date of purchase for defects in workmanship.

Take apart shocks are considered a serviceable shock with a one year warranty on leakage only. Service seal kits are available separately for future maintenance. All other  shocks are covered under our Limited Lifetime Warranty.

Fabtech does not warrant any product for finish, alterations, modifications and/or installation contrary to Fabtech’s instructions. Alterations to the finish of the parts  including but not limited to painting, powdercoating, plating and/or welding will void all warranties.

This warranty does not include  coverage for police or taxi vehicles, race vehicles, or vehicles used for government or commercial purposes.
Also excluded from this warranty are sales outside of the United States of America.

Installation of most suspension products will raise the center of gravity of the vehicle and will cause the vehicle to handle differently than stock. It may increase the vehicle’s  susceptibility to a rollover, on road and off road, at all speeds. Extreme care should be taken to operate the vehicle safely at all times to prevent rollover or loss of control  resulting in serious injury or death. Fabtech front end Desert Guards may impair the deployment or operation of vehicles equipped with supplemental restraining systems/air  bag systems and should not be installed if the vehicle is equipped as so.
