24. Working on the driver side, move back to the 1/2” hard-
ware and add some loctite and torque the hardware attach-
ing the upper shock into the OE location to 65 ft lbs. Repeat
procedure on the passenger side.
25. Locate the new torsion bar keys. Working on the driver
side, install the new torsion bar key back into the cross mem-
ber and carefully tap the torsion bar into the newly installed
key making sure that the line scribed on the torsion bar and
the lower control arm match up. Repeat procedure on the
passenger side.
26. Working on the driver side, install the torsion bar unload-
ing tool and adjust the new torsion bar key up high enough
so that the torsion bar block and bolt can be re-installed.
27. Working on the driver side, install the stock torsion bar
bolt into the torsion bar block. For now, set the torsion bar
bolt about half way in the block. Special note: Once the rear
end installation is complete and the weight of the vehi-
cle is on the ground, proper adjustment for ride height
will occur. Remove the torsion bar adjusting tool and repeat
procedure on the passenger side.
28. Working on the driver side, use a grease gun to grease
the newly installed upper control arm bushings. Repeat pro-
cedure on the passenger side. Special note: It is highly
recommended to grease these bushings every time you
have the oil changed in your vehicle. This will increase
the life of the bushing along with helping eliminate
squeaking.
29. Check and double check and check again to make sure
all steps have been performed properly with the front end.
30. Install the tires and wheels and carefully lower the vehi-
cle to the ground.
31. To begin installation, carefully block the front tires and
wheels so that the vehicle can not roll forward. Safely lift the
rear of the vehicle and support the vehicle with a pair of jack
stands. Place a jack stand on both the driver and the pas-
senger side. Next, remove the rear wheels and tires from
both sides.
32. Place a hydraulic floor jack under the driver and passen-
ger side of the rear axle.
33. Working on the driver side, remove the lower shock hard-
ware attaching the shock to the axle. Save the shock hard-
ware. The upper shock mount does not need to be removed
unless you are replacing the rear shock. Special note: The
OE shocks will be long enough once this suspension
system has been installed but Tuff Country highly rec-
ommends replacing the rear shocks. If you have not
already ordered your rear shocks, please contact Tuff
Country or your local Tuff Country dealer and order your
