95. Locate the (2) 1/4” USS flat washers from hardware
bag 14955NB1. Also, locate the stock rear bracket line
hardware that was removed in step # 85. Working on the
driver side rear shock bracket, re-install the stock bracket
line bracket to the stock rear shock bracket using the
stock hardware and the 1/4” USS washers as spacers.
This will ensure that the shank of the bolt will not rub on
the new shock.
96. Carefully remove the (2) hydraulic floor jack from
under the rear differential.
97. Working on the driver side rear frame rail, if needed,
carefully bend down on the stock rear brake cable
extension bracket to allow for proper brake line
clearance.
98. Install the tires and wheels and carefully lower the
vehicle to the ground.
Step # 99 and # 100 needs to be performed with the
weight of the vehicle on the ground.
99. Working on the driver side, move back to the new
5/8” hardware attaching the stock lower control arms to
the newly installed one piece lower sub frame and torque
to 125 ft lbs. Repeat procedure on the passenger side.
100. Locate (2) 1/2” x 15” bolts and (2) 1/2” unitorque
nuts from hardware bag 14955NB3. Locate (2) new sway
bar end links from hardware bag 14955SL. Also, locate
(8) sway bar end link bushings and (8) sway bar end link
washers from hardware bag 14955SL. Working on the
driver side, install the new sway bar end link and
hardware into the stock location and torque to 32 ft lbs.
Repeat procedure on passenger side.
See Illustration # 29
you are installing into the stock spring assembly has
an offset center hole location, place the longest side
of the add-a-leaf towards the rear of the vehicle. Also
the new add-a-leaf should be installed into the stock
spring assembly in progression in order, from
longest to shortest. The new add-a-leaf should be
installed between the stock overload and the stock
spring pack. The stock overload is usually the un-
arched spring at the bottom of the stock leaf pack.
Also, Tuff Country EZ-Ride Suspension recommends
not using any air tools when installing the new add-a-
leafs into the stock spring assembly. If air tools are
used the centering bolt may strip, causing the stock
spring assembly to come apart. With a suitable cutting
tool, cut off the extra thread from the new centering bolt.
Repeat procedure on passenger side.
91. Locate (2) new 3” lifted blocks. Working on the driver
side, install the new 3” lifted block into the stock location.
Repeat procedure on the passenger side.
92. Carefully raise up on both hydraulic floor jacks at the
same time until the stock spring assembly sits flush with
the newly installed 3” lifted block.
93. Locate (4) 9/16” x 2 3/4” x 12 5/8” square U-bolts.
Locate (8) 9/16” U-bolt high nuts and (8) U-bolt washers
from hardware bag 916NW. Also, locate the stock upper
and lower U-bolt plates that were removed from step #
87. Working on the driver side, install the new U-bolts
into the stock location and secure using the new 9/16”
high nuts and washers. Special note: Make sure to re-
install the stock upper and lower U-bolt plates into
the stock location. Torque to 120 ft lbs. Repeat
procedure on passenger side.
94. Locate the new rear shocks. Special note: New
longer rear shocks are needed, if you have not
already ordered shocks, please contact Tuff Country
or your local Tuff Country dealer and order the
proper shocks. Tuff Country recommends using a
30” fully extended nitrogen gas shock. Locate the new
lower and upper poly bushings and proper shock sleeves
that are packaged with the new shocks and install the
new lower and upper shock bushings and proper shock
sleeves into the lower and upper eyelet of the new
shocks. Special note: Make sure to use a lithium or
moly base grease prior to inserting the new lower
shock bushings and sleeves into the new lower
shock eyelet. This will increase the life of the bushing
as well as prevent squeaking. Locate the upper and
lower shock hardware that was removed from step # 84.
Working on the driver side, install the new rear shock into
the upper and lower stock location and secure using the
stock hardware. Torque to 80 ft lbs. Make sure to use
thread locker or lock tite. Repeat procedure on
passenger side. Tuff Country EZ-Ride Suspension
highly recommends that the shocks are installed with
shock boots. If shock boots are not installed,
