28780VB00A ARM ASSY-REAR WINDOW WIPER

Rear Window Wiper Arm Assembly for Nissan SUVs

This rear wiper arm restores clear rear vision in rain, mud, and dust. It is essential for safe reversing, lane changes, trailer hookups, and off‑road driving. Built for accurate sweep and stable blade pressure, it helps the washer and defogger keep the back glass clean and streak‑free.

How it works

The arm mounts on the wiper motor’s splined shaft and pivots on a spring‑loaded hinge. A tension spring presses the blade evenly against the glass, while the slim profile limits wind lift. The end cap protects the retaining nut from corrosion, and the washer channel directs fluid onto the wipe path for fast cleaning.

Why replace it

Common faults include streaking, chatter, weak contact, or a blade that parks too high or low. Stripped splines cause slipping, a bent arm misses the sweep arc, and a cracked hinge can lock up or flop. Rusted joints and a missing cap accelerate wear and may scratch the glass.

If the arm fails

Rear visibility drops, glass can get marred, the wiper motor is overloaded, and inspections may be failed. In stormy weather or dusty trails, that risk multiplies.

Install tips

Seat the arm fully on clean splines, align to the park mark, tighten the nut to light torque, snap on the cap, and fit a fresh blade for best results.
