89-00 1 Ton Chevy/ GMC Dually Front Kit Part No.75511 Manual
Preparing the Vehicle
1. Elevate the truck and place the frame securely on jack stands.
2. Remove the wheels.
3. Disconnect the sway bar links from each lower control arm.
4. Remove the shock absorbers.
NOTE: We recommend using a Bell Tech drop spindle or equivalent along with this installation
Removing the Spindle
NOTE: Work on one side at a time. The pictures shown are from the passenger side.
1. Put a jack under the passenger side A-arm securely.
2. Elevate the A-arm so that the spring is compressed
3. To gain access to the spring and the frame, we completely removed the spindle from the vehicle. This is done by:
a. Remove the steering rod from the spindle (Figure 2) and remove the brake line bracket bolt from the top of the A- arm.
b. Remove the brake caliper from the spindle and completely remove from the work area (Figure 3).
NOTE: It should not be necessary to disconnect the brake line.
c. Remove the cotter pins on the upper and lower ball joints.
CAUTION: It is highly recommended that a spring compressor is used in order to contain and remove the spring. Use extreme caution. Follow directions and safety guidelines.
d. If a spring compressor is used, tighten the spring compressor, as necessary, to create enough free play for removal.
e. Tie a strap around the spring to keep it from falling out of the vehicle during removal (Figure 4).
f. Loosen top and bottom ball joint nuts. Leave them on the stud, flush to the top. Using a pickle fork or hammer, tap the side of the spindle. Loosen the spindle from the ball joints (Figure 4).
g. Remove the nuts and spindle with the spring still compressed by the jack under the A-arm.
Removing the Coil Spring
CAUTION: Please follow basic safety guidelines during this step. Use a spring compressor if possible.
1. Drop A-arm all the way down until it hangs free.
2. If a spring compressor is used, unstrap and pull spring from the pocket. If a spring compressor was not used, then lightly pry spring from the A-arm pocket with the strap still intact.
3. Remove the strap and coil spring when free from the pocket.
