Symptoms of Fault
Harsh rear suspension impacts or knocking warrant inspection of the additional springs, damper mounts, dampers and surrounding hardware. These symptoms can have several causes, so noise alone does not establish that this component needs replacing.

Why Replacement Matters
Inspecting supporting components during damper renewal helps identify worn items before reassembly. Replace a deteriorated additional spring with the correctly specified version, and assess nearby mounts, dust covers and fixings while access is available.

FAQs

Is this a complete shock absorber?
No. This is the additional helper spring within the rear suspension assembly.

What should be checked before selecting it?
Compare reference 98733330101, the vehicle details and the PR:029 equipment notation. Model designation alone may not distinguish every suspension specification.

Should other components be inspected during fitting?
Check the dampers, mounts, dust covers and associated hardware for deterioration or looseness rather than assuming the additional spring is the only worn component.

Check fitment for your specific vehicle (model, year, engine) before ordering.
