Rear:
59. Remove both rear shocks. Spare tire may need to be removed
to allow access to upper shock mount on driver side.
60. Disconnect rear brake line and vent hose. Remove rear u-bolts.
Jack up frame away from axle to allow installation of new
springs. (See Photo #57)
61. Loosen retaining straps on gas tank. Do not remove the straps.
Only loosen to allow access to front spring eye bolt on drivers
side. Place 2x4 between gas tank and frame; this will allow you
to remove the spring eye bolt.
62.(If installing block and add-a-leaf, skip to step 63.) Install new
rear springs so that the thin part of the degree shim is pointing
forward. The long end of the spring should be toward the rear.
Do not tighten at this time. (See Photo #58 and #59)
63. (Use this step if installing block and add-a-leaf). To perform the
installation of add-a-leafs properly you must use two large C-
clamps to contain the elastic potential energy in the leaf spring
when the center tie bolt is being removed. Attach and tighten a
C-clamp on leaf spring on both sides of the center tie bolt to
hold spring assembly securely together. Using vice grips to hold
the head of the center bolt, loosen and remove it. With care,
slowly loosen an remove the c-clamps and springs bottom over-
load leaf, if equipped. Install new add-a-leaf long end toward the
rear. The leaf will install where it fits in the pack longest to short-
est. Install new center tie bolt but do not tighten the nut at this
time. DO NOT USE THE CENTER TIE BOLT TO DRAW THE
SPRING LEAVES TOGETHER. FAILURE OF ANY COMPO-
NENT CAN CAUSE AN EXPLOSIVE DISASSEMBLY AND
POSSIBLE INJURY! Place one C-clamp on each side of the
center bolt and tighten evenly. Once C-clamp has drawn leaves
securely together, hold the center tie bolt head with vice-grips
and tighten nut. Remove C-clamps. Cut off excess length of tie
bolt. Reinstall leaf springs with 2" block between spring and fac-
tory block. Thickest part of the block should be toward the rear.
64. Let the weight back down on springs being sure that dial pins
on block and spring line up correctly. At this time, install and
tighten all u-bolts and eye bolts. Remove 2x4 from between gas
tank, and tighten straps back down.
65. Install new extended brake line, extended 5/32” vent hose, and
rear shocks. Reinstall factory drive shaft. (See Photo #60 and
#61)
66. Refill transfer case fluid and check transmission fluid.
