         Pickups
         Change shims between upper control arm shaft and support
bracket or turn upper control arm shaft until specifications are
obtained.

         CAMBER

NOTE:    On GLC wagon, camber is not adjustable. If camber is not
         within specifications, inspect suspension for excessive wear
         or damage. Replace components as necessary.

         GLC
         1) Raise front end, support with jack stands and open hood.
         2) Remove 2 mounting nuts holding strut support to fender
apron. Push mounting block down, turn 180

ø

 and tighten mounting nuts.

Note a triangular shaped mark on mounting block. Rotating mark away
from engine changes camber to the negative side and opposite
direction the opposite happens. Check camber angle.

         RX7 & 626

NOTE:    See procedure given under RX7 & 626 Caster adjustment.

         Pickups
         Change shims between upper arm shaft and support bracket
until specifications for camber are within limits.

         TOE-IN

         626 (Front)
         Loosen lock nuts and turn tie rods equal amounts. Both tie
rods are right-threaded, to increase turn right tie rod toward front
of vehicle and to decrease turn left one toward rear of vehicle by
the same amount. One full turn equals .24" (6 mm). If boot is twisted
or dented, loosen band and straighten boot.

         All Other Models (Front)
         1) Raise front of vehicle. Turn wheels by hand and mark a
line in center of each tire tread. Place vehicle in straight-ahead
position and lower vehicle to ground.
         2) Measure distance between marked lines at both front and
rear of wheel. Make sure measurements are made equal distances from
ground.
         3) Loosen lock nuts and turn tie rods until adjustment is
correct. Tighten lock nuts with bolts horizontal and below rod. This
procedure will prevent interference with center link.

         GLC FWD & 626 (Rear)
         1) Release emergency brake. Mark front and back of tire at
same height as center of wheel. Mark center lower section of
crossmember. Points marked on tires and crossmember form a triangle
and are reference points for adjusting rear toe-in.

         2) Turn spacer (star wheel) to make the points from rear of
tire to center of crossmember equal. See Fig. 2. Turn both right and
left spacers the same amount to adjust toe-in.

Fig. 2:  GLC & 626 Star Wheel Adjustment

         3) On GLC only, check parallelism of body and rear wheel.
Use existing mark on rear of tire and hole on each side member.
Measure from hole on one side to tire on the other. Repeat using
other hole and tire. If measurements are not equal, loosen 2
crossmember mounting nuts on each side. Move crossmember so
measurement is within .2" (5 mm).
