The Edge Advanced Suspension Instruction Sheet
This Kit must be installed with THE EDGE 4.5” HANGER KIT (part no.3-4000) or THE EDGE 6” FRONT SPRING KIT (part no.3-6000) or THE EDGE 8” FRONT SPRING KIT (part no.3-8000).
- Front Driveshaft for 8” Front Spring kit must be modified.
INSTRUCTIONS:
1. Jack up the front end of the truck and support the frame at the front frame rails with jack stands. NEVER WORK UNDER AN UNSUPPORTED VEHICLE. Remove front tires.
2. Remove the brake calipers and tie them up out of the way. DO NOT ALLOW CALIPERS TO HANG FROM THE BRAKE LINES! Supporting the front axle with two floor jacks, remove the front shocks and sway bar end links. Remove the cotter pin and castle nut from the drag link at the pitman arm. Using a tie rod puller, separate the tie rod from the pitman arm. Remove the bolt from the top end of the pan-rod bar, where it connects to the frame bracket. Remove the three bolts securing the pan-rod bar bracket to the frame and set the bracket aside.
3. Remove the bolts securing the front drive shaft to the axle yoke. Tape the bearing caps on the front u-joint and remove the driveshaft from the transfer case. Remove all four u-bolts from the front axel. Slowly lower the two floor jacks supporting the front axle to clear the front leaf springs. Loosen the four front leaf spring shackle bolts, DO NOT REMOVE THEM. While supporting the leaf spring, remove the front bolt followed by the rear bolt, separating the leaf spring from the shackle. Set the leaf spring aside and repeat this step on the opposite leaf spring.
4. Remove the nut securing the original pitman arm to the steering box shaft. A pitman arm puller must be used to remove the pitman arm from the steering shaft. Once off, replace the stock pitman arm with the drop pitman arm supplied in the box kit. If the splines on the pitman arm do not match, your truck is an early 1999 model and you will need box kit part number 3-1000 to replace this part number 3-1020. Align the master splines on the steering shaft, replace the original washer and nut, and torque the new unit in place at 200-225 ft-lbs.
