What This Product Does

The damper restrains repeated spring movement after the rear wheels encounter an uneven surface. Working alongside the springs and mounts, it moderates suspension oscillation rather than carrying out the spring's supporting role.

Functions

• Controls rear spring oscillation.
• Limits repeated bouncing after road disturbances.
• Regulates suspension movement as wheel loads change.

Symptoms of Fault

• Repeated rear bouncing after bumps.
• A floating or unsettled sensation from the rear suspension.
• Visible fluid leakage around the damper.
• Knocks when crossing uneven surfaces.
• Irregular rear tyre wear.
  
  

These signs can also arise from worn mounts, bushes or other suspension components. Inspect the complete assembly before attributing a noise or handling change to the shock absorber.

Why Replacement Matters

A leaking or internally worn damper may no longer control suspension movement consistently. Renewal addresses this wear while retaining the specified standard-chassis application. Inspect the rear mounts, bushes, springs and protective components during the repair, and replace any associated items found to be damaged.

FAQs

Should both rear dampers be renewed together?
Replace rear dampers as a matched pair to avoid combining differently worn units. Two individually supplied absorbers are required for the rear axle.

Must the mounts also be changed?
Inspect them during removal. Wear, damage or noise may justify renewal, but replacement should follow their condition.

Is an alignment check needed?
Have the suspension geometry checked after the work where the installation procedure or disturbed components require it.
