15. Install the modified bearing plate back to the strut using
the OE hardware. Make sure to use loctite and torque to 55
ft lbs. Special note: make sure that the lines scribed ear-
lier in the installation line up with each other.
16. Locate the new driver side strut spacer. Install the driver
side strut spacer on the newly modified strut and secure
using the stock hardware. Make sure to use loctite and
torque to 45 ft. lbs. Place the driver side strut aside for later
installation into the vehicle.
12. Place a clamp on the bottom coil portion of the coil
spring and strut plate. This will help keep the coil spring in
the proper location.
13. 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.
14. Locate the new pre-load spacer. Place the driver side
bearing plate on a work bench upside down. Remove the
isolator from the bearing plate and install the pre-load spac-
er to the bearing plate then re-install the isolator. Make sure
that the lines that were scribed earlier in the installation
match up with each other.
