This will help increase the life of the bushing and also
help prevent squeaking.
83. Working on the driver side, remove the inner bolt that
connects the transfer case cross member to the stock loca-
tion. The stock hardware may be discarded. Repeat proce-
dure on the passenger side.
84. Locate the lateral compression arm plate. Locate (2)
7/16” x 5” bolts, (4) 3/8” USS flat washers, (2) 7/16” uni-
torque nuts and (2) 1/2” harden u-bolt washers from hard-
ware bag # 2 in hardware box 56070NB. Install the new lat-
eral compression arm plate to the stock transfer case cross
member using the new 7/16” x 5” bolt and hardware on
both the driver and the passenger side of the vehicle. Do
not tighten at this point. Special note: We want to install
the new 1/2” harden u-bolt washers between the back
side of the new lateral compression arm plate and the
stock transfer case cross member. Make sure we do
this on both the driver and passenger side. Also, you
will notice that there are (2) 3/8” holes in the center of
the new lateral compression arm plate, once the new
lateral compression arm plate is installed these holes
will be facing the top of the vehicle.
85. Using the new holes in the new lateral compression
arm plate as a guide, carefully drilll (2) 5/16” holes into the
front portion of the stock transfer case cross member.
86. Locate (2) 3/8” x 3/4” self threading bolts from hardware
bag # 2 from hardware box 56070NB. Secure the new lat-
eral compression arm plate to the stock transfer case cross
member using the new 3/8” x 3/4” self threading bolts to the
holes that were drilled previously into the the stock transfer
case cross member. Make sure to use thread locker or loc-
tite and torque to 18 ft lbs. Now move back to the newly
installed 7/16” x 5” bolt holding the new lateral compression
arm plate to the stock transfer case cross member and add
some thread locker or loctite and torque both bolts 48 ft
lbs.
87. Locate (4) 1/2” x 3 1/2” bolts, (8) 7/16” USS flat wash-
ers and (4) 1/2” unitorque nuts from hardware bag # 3 from
hardware box 56070NB. Also, locate the new lateral com-
pression arms with the new bushings and sleeves installed
in them. Install the new lateral compression arms to the
newly installed lateral compression arm plate using the new
1/2” x 3 1/2” bolts and hardware. Do not tighten at this
point. Now swing the new lateral compression arms for-
ward and install them into the newly installed rear cross
member using the new 1/2” x 3 1/2” bolt and hardware.
Move back to the (4) new 1/2” x 3 1/2” bolt and add some
thread locker or loctite and torque all (4) bolts to 55 ft lbs.
88. Place a hydraulic floor jack under the driver side of the
rear differential and carefully raise up on the hydraulic floor
jack until it makes contact with the rear differential.
89. Working on the driver side, remove the stock rear shock
from the stock upper and lower location. Save the stock
lower mounting hardware but the upper mounting hardware
may be discarded. The stock shock may be discarded.
Special note: New longer rear shocks are needed after
this suspension system has been installed and the rear
shocks need to be ordered as a separate part #. If you
have not already ordered your rear shocks, please feel
free to contact Tuff Country or your local Tuff Country
dealer and order your new rear shocks. Tuff Country
recommends installing a 30” fully extended nitrogen
gas shock in the rear. Repeat procedure on the passen-
ger side.

cable bracket from the rear differential. Save the stock
hardware. Repeat procedure on the passenger side.
91. Working on the passenger side, loosen but do not
remove the stock rear u-bolts. We want to do this so that
we can move the rear differential forward or rearward once
we install the new rear add-a-leafs and block on the driver
side.
92. Working on the driver side, remove and discard the
stock u-bolts and hardware. Save the stock lower u-bolt
plate and upper bump stop plate.
93. Working on the rear differential, we want to remove the
stock brake line bracket and save the stock hardware.
94. Remove the stock ABS bracket from the stock location
above the spare tires. Make sure to save the stock hard-
ware.
95. Remove the stock rear brake line brackets that con-
nects to the rear differential just to the driver and passen-
ger side of the rear pumpkin. Save the stock hardware.
96. Carefully lower down on the hydraulic floor jack enough
so that the new rear add-a-leafs and the new block can be
isntalled. Special note: Even though we have removed
