Spohn 738-QX - Manual (Page 2)

10. Place the strut mount retainer underneath the ¼” plate.
11. Position your new upper strut mount, then install the supplied bolts, washers,
and nuts (bolt, flat washer, plate, strut mount, flat washer, nut). You want to install
the bolts from the underside of the strut tower, through the plate and strut mount
and install the nuts on the top of the strut mounts.
12. Re-align your upper strut mounts to the line you drew around them earlier and
then tighten the three nuts.
13. Place a thrust washer, Torrington thrust bearing, and then another thrust washer
on top of the spring (washer, bearing, washer). Hold in place with a piece of scotch
tape wrapped around the spring.
14. Swing your strut back inside the wheel well. While guiding the top of the strut
shaft and the spring, jack up the a-arm until the strut shaft is through the strut
mount and re-install the top strut mounting nut. Tighten the nut. Make sure the
spring, washers, and bearing are properly positioned and seated around the coil over
mounting hat on the underside of the strut mount.
15. Once both sides have been installed, re-install the wheels and lower the car to
the ground. With the car in neutral, roll the car front and back several times to
properly seat the springs.
16. Using the supplied spanner wrenches, adjust the spring seat until you have
achieved the desired ride height. Whenever an adjustment has been made, roll the
car as above to seat the springs properly. Once you have the setting you desire,
tighten the spring seat adjuster’s set screw with an allen wrench and then tighten
the locking jam ring. You will note that adjustments can be made with the
suspension loaded, however, if you jack the car up until the tire is off the ground and
then do your adjustments, it is much easier, and can normally be turned by hand.
17. Take your car for a front end alignment.
Spindle Modification Instructions
In order to install the QA1 adjustable front struts for the 1982-1992 GM F-Body
Camaro and Firebird some grinding or machining of the factory spindles is required
to gain clearance with the QA1 strut. We have found that the easiest method to do
this is with a hard wheel grinder. It is not a major project, in fact with the factory
spindles removed from the car it's a job that will only take a few minutes to
complete.
The first thing we want to point out is that there are two different types of factory
spindles for the 1982-1992 F-Body Camaro and Firebird. There is what we call a
"light" spindle and a "heavy" spindle. We're not sure of the exact year range for each
type spindle, but we're guessing that the 1989-1992 cars have the heavier spindle,
although some earlier years may as well. The heavier spindles have some more meat
to them and will require an additional area that needs to be ground. Let's get
started.
