REAR SUSPENSION MEMBER

• When installing the upper and lower rubber seats for the rear coil

springs, the arrow embossed on the rubber seats must point out

toward the wheel and tire assembly.

• To connect the rear load leveling air suspension hoses, the lock

ring must be fully seated in the fitting. Insert the hose (B) into the

the spare tire, jack, hand tools, and mats are in their designated positions) with the tires on level ground.

• Check the wheel alignment. Refer to
