Tuff Country 54070 - Toyota Tundra 07-14 4 lift kit - Manual (Page 7)

Tuff Country EZ-Ride Suspension recommends a wall
mounted strut compressor be used when performing
the steps that talk about installing the pre-load spacer
into the strut. If you do not have a wall mounted strut
compressor, please have these steps performed by your
local Toyota Dealership
18. Place the driver side strut into a wall mounted strut com-
pressor. Scribe a line on the bearing plate, rubber isolator,
the top coil of the strut, the bottom coil of the strut and bot-
tom strut plate. Special note: If these steps are not per-
formed properly re-installing the strut back into the vehi-
cle will be difficult.
19. Place a clamp on the bottom coil portion of the coil spring
and strut plate. This will help keep the coil spring in the prop-
er location.
20. Carefully compress the driver side strut until the upper
bearing plate can be removed. Remove the nut and hard-
ware from the upper bearing plate and save the hardware for
later re-installation. Special note: Notice that on top of the
bearing plate there is an arrow indicator marking. This
marking is so that the coil over can installed back into
the vehicle the same way it was removed, hence the
bearing plate needs to be installed the same way it was
removed.
21. Locate the new pre-load spacer. Remove the OE isola-
tor from the bearing plate and discard. Install the new pre-
load spacer to the bearing plate install it to the OE coil over
using the OE hardware. Make sure to use loctite and torque
to 55 ft lbs. Special note: Make sure that the bearing
plate is re-installed back into the same location as it was
removed earlier in the installation.
