1. Push on the damper as shown.
2. Compress the damper assembly by hand, and check for smooth operation through a full stroke,
both compression and extension. The damper
should extend smoothly and constantly when
compression is released. If it does not, the gas is
leaking and the damper should be replaced.
3. Check for oil leaks, abnormal noises, or binding during these tests. 1. Install the damper mounting bushing (A) onto the
damper unit. Position the damper assembly (B)
between the body and tra iling arm.
NOTE: Be careful not to damage the body.
2. Position a floor jack under the tra iling arm to
support the suspension, then install the new
damper mounting bolt (A).
3. Loosely tighten the damper mounting bolt.
4. Raise the rear suspension with the jack until the vehicle just lifts off the safety stands, then tighten
the damper mounting bolt to the specified torque
value.
