Hardbody/Pathfinder Front Suspension Lift

  1. Raise the front of the truck and support with jack stands. Remove both front tires and front shock absorbers.
  2. Place jack under one of the lower control arms and raise just until the truck lifts off the jack stand.
  3. Loosen the two large nuts on either end of the upper control arm cross shaft.
  4. Remove the four bolts that attach the upper ball joint to the upper control arm.
  5. Remove the two large bolts that hold the upper control arm cross shaft to the frame. Remove the a-arm.
  6. Press or burn out the old bushings. Install the new bushings, sleeves and old cross shaft into the new a-arms. Make sure to grease the inside of the sleeves and bushing before putting them on the cross shaft.
  7. Reinstall the a-arms. Make sure to use Lock-Tite on all bolts.
  8. Install longer shocks if applicable.
  9. Repeat steps 2-8 on the other side of the truck.
  10. Lower the truck and check the ride height. An approximate ride height setting is when the upper a-arm metal stop is 1/2" off the rubber bump stop. Adjust torsion bars to this setting. NOTE: The distance between upper A-arm bump stops and rubber bump stop below do not get any less than ½”.
  11. After installing the suspension lift the front of the truck must be realigned. This requires adjustment of the camber, caster and height and should be done by an alignment shop. Camber must be adjusted between 0.1° positive to 1.1° positive. Caster does not have to be in factory specification, but should be set to be the same on both sides.

  13. These new a arms are designed to give your Nissan a safe, smooth riding lift and allow more ground clearance, more room for larger tires and wheels, and more wheel travel.
  14. The exact amount of lift you will receive will vary depending on the size of the tire and the width and offset of the wheel and adjustment of torsion bars.
  15. Do not remove or shorten the rubber down stops on 4x4 trucks. This will damage the front CV joints.
  16. Do not over tighten the torsion bars. This will create a severe ride and hurt the handling by eliminating all the down travel.
  17. Do not try to gain more height by shimming out the A arm. For correct alignment and lift you will need little shimming. If you add too many shims or spacers the bolts holding the crossbar to the frame will become too short and possibly strip out. Also, the crossbar will hit the shock absorber.

Re-indexing Torsion Bars

  1. Jack up front of vehicle. This helps in removing preload on bar and allows for removal of torsion bar.
  2. Back off adjuster bolt.
  3. Note location of adjuster. This makes indexing easier because you can compare locations of the adjuster.
  4. Remove rear adjuster or remove torsion bar from front anchor, which ever is easier for your particular model.
  5. It is sometimes necessary to have someone push down on the tire to get the suspension at full droop. This will help to get more adjustment if you need it while re-indexing.
  6. Reinstall torsion bar or adjuster so that you have moved the rear adjuster away from the adjuster bolt anchoring site, which is usually a cross member.
  7. Tighten adjuster bolt until preload is felt on torsion bar.
  8. Let vehicle down and check ride height. If you need more, jack vehicle up and tighten adjuster bolts until desired ride height is achieved.
  9. Bolts should be checked and tightened periodically.
