Apply grease to the rear shock absorber bushing.
Insert the rear shock absorber bushing and apply grease to
the exterior exposed edge of the bushing.
Assembly is the reverse of disassembly. Torque the shock absorber nut and bolt to 25 ft-lbs. There is
no torque specification for the swingarm pivot axle nuts. Tighten the swingarm pivot axle nuts equally
such that there is no side-to-side play in the swingarm and the swingarm pivots up and down with
minimal drag.
