Suspension Control ( Automatic - Electronic ): Service Precautions

Suspension Control System (REAS)

PRECAUTION
1. Precaution to handling the center unit and the shock absorber.
a. Replacement of each unit is allowed if there is no oil leakage. But, in case of oil leakage from the system, replace both the absorber and the center unit as a set.
b. For replacement of the system, make it possible to replace a unit only at the first time and replace the system as a set of delivery at the second time or later.
c. When carrying each unit, be sure to hold the body of the unit and never hang the body by holding joint parts or hoses. Also, do not deform metal tubes.
d. Each unit should not be at a high temperature at the time of replacement.
e. Since the shock absorber could be damaged by a sudden temperature change as being disconnected from the center unit, be careful about its storage.
f. Do not loosen the union bolt except the time of the disposal of each unit.
g. Never loosen the absorber hoses and the flare nuts at the joint parts.





2. Precaution of removal and installation of the center unit and the shock absorber.
a. Conduct the operations as stretching all the shock absorbers out by jacking up the vehicle.
b. Never put a great compressive load to the shock absorbers, such as contacting the tires on the ground, before connecting them to the center unit to avoid the break down.
c. Avoid the contacting surfaces of the joint parts to get any foreign objects, and wipe them away so as not to damage the O-rings in case of the adhesion.
d. Be sure to fit the detents attached to the bracket on the front absorber hose side, the rear absorber hose side and the middle unit joint part into a hole on the frame side.
e. Never loosen the absorber hoses and the flare nuts at the joint parts.
f. For the joint that is connecting the supplied parts, tighten the joint as checking the gap spacing shown in the illustration.
Dimension of gap: 1 mm (0.04 inch)
Reference torque: 25 Nm (255 kgf-cm, 18 ft. lbs.)
