How It Works And Why It Fails
The bearing supports the rear wiper shaft and ensures concentric, low-friction rotation of the wiper arm. Common failure modes include bearing wear from long-term use, corrosion and water ingress on tailgates, plastic gear deterioration in the motor drive, and shaft play caused by worn bushes. Symptoms of failure are excessive play at the wiper arm, irregular wiping patterns, grinding or squeaking noises, and in some cases complete loss of rear wiper movement.
Replacement Procedure (Overview)
Recommended For Experienced Mechanics And Skilled DIYers.
- Park vehicle on a level surface and switch off ignition. For safety, isolate the battery before working on electrical connections.
- Remove the rear wiper arm (usually by removing the cover cap and the retaining nut), then detach the wiper blade.
- Remove interior tailgate trim to access the wiper motor/mechanism assembly. Take care with clips and electrical connectors.
- Disconnect the electrical connector to the rear wiper motor and unbolt the motor/mechanism assembly from the tailgate.
- Replace the worn bearing/shaft assembly or the complete mechanism as required. Ensure the new bearing is correctly seated and the shaft aligns with the motor drive.
- Reassemble in reverse order, restore the battery connection, and verify correct park position and sweep pattern. Adjust wiper arm position if necessary so the blade rests in the correct park location.
Installation Recommendations
- Perform installation on a dry day or in a dry workshop to avoid water ingress during fitting.
- Use appropriate trim tools to avoid breaking interior plastic clips and panels.
- Check seals and grommets on the tailgate for damage; replace if water ingress is present to protect the new bearing and motor.
- After installation, cycle the wiper to check for smooth operation and correct park position before final assembly.
- If the drive gear or motor shows signs of wear, replace the complete motor/mechanism assembly to avoid premature repeat failures.
Most Common Reasons For Failure
Long-term mechanical wear, Water Ingress And Corrosion, Degraded Seals On The Tailgate, Overloading Due To Ice Or Heavy Debris, And Age-Related Deterioration Of Plastic Drive Components.

Buying Advice
Search by OEM part number for fastest match: 9654116177, 3398005649, 6405EE. Choose a complete mechanism if the motor or plastic drive components show wear; replacing only the bearing may be a short-term fix if other drive elements are compromised. Ideal for workshops and competent DIYers who service Citroën/Peugeot rear wiper systems.
