(See Photo # 9). Remove the rear U-bolts using a 21mm socket.
15. Lower the axle to gain access to the rear leaf spring. To perform
the installation of add-a-leafs properly you must use two large
C-clamps to contain the elastic potential energy in a leaf
spring when the center tie bolts are being removed. Attach &
tighten a C-clamp on each end of the leaf spring to hold the
leaf spring assembly securely together. (See Photo # 10)
Using locking pliers to hold the head of the two center bolts,
loosen & remove them. With care, slowly loosen & remove
the C-clamps.

overload leaf, new Skyjacker add-a-leaf, & OEM leaf spring
pack. Only finger tighten the nut & be sure to install the add-a-leaf so the
teflon wear pad in towards the rear of the vehicle.
17. DO NOT USE THE CENTER TIE BOLTS TO DRAW THE SPRING LEAVES TOGETHER.
FAILURE OF ANY COMPONENT CAN CAUSE AN EXPLOSIVE DISASSEMBLY AND
POSSIBLE INJURY! Place one C-clamp on each side of the center bolts & tighten evenly. Once
the C-clamps have drawn the leaves securely together, hold the center tie bolt heads with
locking pliers & torque the nuts to 41 Ft. Lbs. (See Photo # 11) Remove the C-clamps & cut off
the excess length of the tie bolts. Install the new Skyjacker U-bolts & torque to 130 Ft. Lbs.
