Prepare to Install Rear
Suspension
1. Raise the rear of the truck enough for the tires
to clear the ground and use jack stands on the
frame to support the truck. Remove the rear
tires and wheels.
2. Carefully remove the OE shock absorbers. It
may be necessary to raise the differential hous-
ing slightly to facilitate their removal.
3. Unbolt the driver side emergency brake line
hanger from the frame rail. Save the OE bolt
for reuse.
4. Unclip the rubber ABS line from the frame
rails.
5. Unbolt the rear brake line bracket from the rear
axle differential housing. Save the OE bolt for
reuse.
6. One side at a time, support the differential
housing on the side being modified. Remove
the “U” bolts from that axle end and discard.
Carefully lower the differential away from the
OE springs. Remove and discard the OE riser
block from its mount pad. Take careful note of
the position of the factory spring packs.
