Assemble TWO rear camber linkages by performing the following steps.
1. Thread ball joints onto the ends of a #302615 turnbuckle.
Important: There are two types of ball joints: two with large holes and two with small holes.
Thread the ball joint with the LARGE hole onto the LONGER end of each turnbuckle.
Adjust the turnbuckles to a length of 51.5 mm, measured end-to-end.
The ball joints should be perpendicular (90°) to each other.
Note: Each turnbuckle has a CCW thread on one end and a CW thread on the other end.
Mount the #303093 rear shock tower to
the rear bulkheads with four #902306
(SH M3x6) screws.
Assemble the TWO rear suspension arms by performing the following steps.
1. Place the assembled linkage so the ball joint with the SMALL hole is atop
the rear upright.
2. Pass a #902310 (SH M3x10) screw downward through a #307454 pivot
ball and turnbuckle ball joint, and thread into the INNERMOST hole in the
top of the rear upright. Tighten until the pivot ball snaps into the ball joint,
and then tighten the whole assembly.
3. Snap the other ball joint (with the LARGE hole) onto the alu mount on the
rear shock tower.

Install both rear uprights by performing the following steps.
1. Place the driveshaft plastic cap into the diff outdrive slot.
Insert the rear upright into the end of the rear lower arm as
shown. Align the hole in the bottom of the rear upright and
holes in the arm.
2. Slide a #307320 pivot pin through the aligned holes.
Make sure the flat spot on the pivot pin is toward the
bottom.
3. Thread and tighten the #901305 (SB M3x5) set screw
in the bottom of the rear upright until it is tight on the pivot
pin. Be very careful not to overtighten the screw, as the
threads may strip in the composite rear upright.
Check both rear uprights for freedom of movement.

INITIAL POSITION
Check the rear suspension for freedom of movement.
The suspension arms must fall freely when lifted up then dropped.
If there is any binding that prevents the arms from moving freely, lightly squeeze the ball joints with pliers, and then recheck.
