What This Product Does

This eccentric fastener forms part of the rear suspension connection between the trailing arm and spring plate. It is a hardware component, rather than a complete spring plate or trailing-arm assembly.

Technical Details

• Part reference: 90133313305.
• Brand: OE Match.
• Installation position: rear trailing-arm/spring-plate connection.
• The supplied rear-axle diagrams identify this component as an eccentric and specify two per assembly; this is not a two-piece set.

Symptoms of Fault

Rear suspension noises, irregular tyre wear or inconsistent alignment warrant inspection of the complete assembly. Bushes, mounts and other suspension components can produce similar symptoms, so these signs do not establish that the eccentric bolt is faulty.

Why Replacement Matters

Renewal may be appropriate when inspection identifies damaged or corroded suspension hardware. Check the adjoining components during the repair rather than replacing the bolt solely on the basis of noise or handling symptoms.

FAQs

Is this a complete spring plate?
No. The product is the eccentric bolt used at the trailing-arm connection.

Should alignment be checked afterwards?
A rear geometry check is appropriate following work that disturbs the spring-plate or trailing-arm settings.

How do I confirm the correct component?
Compare reference 90133313305 with the original hardware and check the vehicle application. Diagram positions differ between assemblies.
