15. Apply a liberal amount of grease to the outside faces of all four bushing ends. See the

end of these instructions for information on what type of grease must be used.

16. Mount the a-arm into the frame mounts and loosely install both mounting bolts. Do

NOT completely tighten them, just lightly snug the nuts.

Note: We have installed either polyurethane or Delrin® bushings, both of these are
much more resistant to flex than the factory rubber bushings, so it may be necessary

to tap the a-arm into the frame mounts using a soft hammer.

17. Install the fully compressed coil spring into the top spring mount in the frame. Then

swing our lower a-arm up and guide the bottom of the coil spring over the short spring

centering tube that is welded to the bottom of our lower a-arm's spring pocket. Make
sure that the coil spring is properly clocked. The end of the coil spring should butt

tightly against the face of the spring ramp that is welded to the bottom of our lower a-
arm's spring pocket.

18. Position a jack under the a-arm in the area of the ball joint.
19. Remove the block of wood you placed underneath the upper a-arm.

20. Jack up on the a-arm until the ball joint is fully seated in the spindle. Install the

supplied castle nut and fully tighten, then install the supplied cotter pin and bend it

over. Remove the jack.

21. Loosen the internal spring compressor and remove it through the bottom of the a-arm.

Make sure the coil spring remains clocked correctly against the face of the lower spring
ramp when the spring is fully uncompressed.

22. Install the front shock by sliding it up through the bottom of the a-arm. Install the

bushing, washer, and nut at the top frame mount and fully tighten. Then install the

two supplied 3/8” x 1.25” long bolts with the 3/8” flat washers placed under the bolt
heads and 3/8” flanged lock nuts on the underside to mount the bottom shock t-bar to

the base of our a-arm. Fully tighten.

Note: We recommend mounting the t-bar to the TOP side of the a-arm. It is mounted
to the bottom side from the factory. Mounting it to the top side is much stronger.

23. Repeat Steps 4-22 on the passenger's side of the vehicle.

24. On both sides of the vehicle loosely connect the top of the sway bar end links to the

front sway bar. The bottom of the end link is fully installed and tightened when we

assemble the a-arm. Remove the Nylock® nut from the top of the end links and then
sandwich the front sway bar between the two bushings (same as the factory end link).

Then install the 3/8” Nylock® nut and make it snug, but not fully tightened.

25. Safely lower the vehicle to the ground.

26. With the vehicle on the ground and the suspension loaded, tighten both of the

mounting bolts that go through the a-arm bushings at the frame mounts on both sides

of the vehicle.

27. With the vehicle on the ground and the suspension loaded, tighten the 3/8” Nylock®

nut on the top of both of the front end links. Tighten the nut until you see the
bushings starting to deform, then STOP.

28. Grease all four of the bushings (two per side) through the grease fittings. 4-5 pumps

from a grease gun in each bushing is plenty, do not grease more than that.

VERY IMPORTANT: The bushings come pre-lubed. DO NOT use any petroleum based

grease on polyurethane bushings! Polyurethane bushings must be lubricated with
synthetic silicone based waterproof grease. These are the bushing manufacturer’s

recommendations to prevent premature bushing wear, and will keep things "squeak-
free". You can order this grease from Spohn Performance using our Part# 902.

Do not over grease the bushings! You only need a couple pumps of grease.

Over greasing will cause the bushings to balloon from the hydraulic pressure
inside of the bushing sleeves and they will fail!
