REMOVAL & INSTALLATION CRV and 4-Cylinder Odyssey Models
- Remove the cup holder from the top of the right rear interior trim. Remove the cup holder, storage tray, and jack from the left rear interior trim.
- Raise and support the vehicle safely.
- Remove the rear wheels.
- Place a floor jack under the lower control arm and raise it slightly to compress the spring.
- Remove the lower shock mount flange bolt and the knuckle flange bolt.
- Unbolt the shock mount from inside the vehicle. Remove the shock from the vehicle.
- Check the shock mount and bushings and replace any that are damaged. Assemble the mount, bushing, and stopper on the shock.
- Install the shock into the vehicle. Install new self-locking upper mounting nuts.
- Raise the lower control arm with a floor jack. Be sure the coil spring is properly seated.
- Install the shock absorber and knuckle flange bolts.
- Raise the jack enough to take up the weight of the vehicle. Tighten both of the flange bolts to 76 ft. lbs. (103 Nm).
- Lower the floor jack. Install the rear wheels. Lower the vehicle.
- Tighten the shock mount nuts to 28 ft. lbs. (39 Nm), and the shock piston nut to 22 ft. lbs. (29 Nm). Install the jack, tool tray, and cup holders.
- Tighten the wheel nuts to 80 ft. lbs. (108 Nm).
- Check and adjust the rear wheel alignment as necessary.
V6 Odyssey Models
- Carefully raise and support the vehicle.
- Remove the rear wheel.
- Place a jack under the lower control arm and lift the arm slightly.
- Remove the shock upper flange bolt from the body.
- Remove the self-locking nut from the stud on the knuckle.
- Compress the shock by hand and remove it from the vehicle.
- Compress the shock by hand and install it on knuckle mounting stud.
- Loosely install the lower shock self-locking nut.
- Extend the shock upward into the upper flange on the body and loosely install the flange bolt.
- With the jack placed under the lower control arm and lift the arm until the jack begins to support the weight of the vehicle and torque the upper flange bolt to 47 ft. lbs. (64 Nm), and the self-locking nut to 47 ft. lbs. (64 Nm).
- Remove the floor jack from the lower control arm.
- Install the rear wheel and tighten the wheel nuts to 80 ft. lbs. (108 Nm).
- Check and adjust the rear wheel alignment.
- Test drive the vehicle and check for proper operation.
The purpose of the shock absorber is simply to limit the motion of the spring during compression and rebound cycles. If the vehicle is not equipped with these motion dampers, the up and down motion would multiply until the vehicle was alternately trying to leap off the ground and to pound itself into the pavement.
Contrary to popular rumor, the shocks do not affect the ride height of the vehicle. This is controlled by other suspension components such as springs and tires. Worn shock absorbers can affect handling; if the front of the vehicle is rising or falling excessively, the "footprint" of the tires changes on the pavement and steering is affected.
The simplest test of the shock absorber is simply push down on one corner of the unladen vehicle and release it. Observe the motion of the body as it is released. In most cases, it will come up beyond it original rest position, dip back below it and settle quickly to rest. This shows that the damper is controlling the spring action. Any tendency to excessive pitch (up-and-down) motion or failure to return to rest within 2-3 cycles is a sign of poor function within the shock absorber. Oil-filled shocks may have a light film of oil around the seal, resulting from normal breathing and air exchange. This should NOT be taken as a sign of failure, but any sign of thick or running oil definitely indicates failure. Gas filled shocks may also show some film at the shaft; if the gas has leaked out, the shock will have almost no resistance to motion.
See Figure 1
While each shock absorber can be replaced individually, it is recommended that they be changed as a pair (both front or both rear) to maintain equal response on both sides of the vehicle. Chances are quite good that if one has failed, its mate is weak also.
