Description
Overview
Rear wiper arm designed for Citroën C4 with a fitted wiper blade. Supplied under part number 6429X8 for PSA Citroën/Peugeot rear wiper assemblies. Note: blade quality is not guaranteed; the arm itself is reported to be in full working order.
Function And Common Faults
The rear wiper arm holds the wiper blade and transmits motion from the rear wiper motor to clear the rear window. Common reasons for replacement include corrosion at the mounting splines, seized or damaged fastening nuts, bending from ice or impacts, and general wear. Wiper blades typically wear faster than the arm; streaking, skipping or poor contact indicate blade replacement is also required.
Installation Guide
Replacement is straightforward for professional workshops and experienced DIYers. Typical steps:
- Park the vehicle, switch off the ignition and ensure the wiper is in the parked position.
- Lift the rear arm off the glass and remove any protective cap covering the securing nut.
- Undo the securing nut and pull the arm straight off the splined shaft (apply penetrating lubricant if seized).
- Fit the new arm, align the splines correctly, hand-seat the nut and tighten to the manufacturer’s torque specification, then replace the cap.
- Lower the arm, test full travel and check for correct blade contact and clearance.
If the arm is difficult to remove do not force it; use appropriate tools or professional assistance to avoid damaging the motor linkage or glass.
Durability And Maintenance
Regular inspection for corrosion, play at the pivot and secure fastening helps extend life. When removing the arm, clean and lightly lubricate splines and threads with an anti-seize product before reassembly to reduce future corrosion and seizing.
