Installation Recommendations

1. Park vehicle on level ground and switch ignition off. Remove the plastic cap covering the wiper arm nut.
2. Mark the position of the old arm on the glass or hood hinge to preserve correct park position.
3. Loosen and remove the retaining nut and lift the arm off the splined pivot—use a puller if seized, avoiding damage to the windshield.
4. Fit the new arm onto the splines in the marked position, tighten the retaining nut to the manufacturer’s torque specification and snap the cap back on.
5. Install the wiper blade, verify sweep and park position by briefly switching the wipers on. Adjust if necessary.

Most Common Failure Reasons

Wiper arms typically fail due to corrosion at the pivot/spline, mechanical bending from impacts, seized or rounded retaining nuts, or loss of spring tension that prevents proper contact between blade and glass. Exposure to road salt, ice and aggressive wash cycles accelerates wear. Regular inspection of arm alignment, pivot play and secure mounting reduces sudden failures.

Why Choose This Part

This wiper arm carries OE-compatible codes to simplify identification and replacement. It is a practical choice when the original arm is bent, the spline is worn or the arm no longer holds the blade with the correct pressure—restoring safe visibility and reliable wiping performance.

Notes For Buyers

Searching by product code (6405V2, 6405HF, 6822VJ) is the quickest way to confirm fitment. Suitable for technicians and competent DIY mechanics familiar with basic removal and installation procedures.

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.

Why Buy
