Rear wiper arm nut cover for GM vehicles

This two-piece set of black plastic caps snaps onto the rear wiper arm nut on a long list of Buick, Cadillac, Chevrolet, GMC, Hummer and Pontiac models from 2004 through 2019. The covers shield the exposed nut from corrosion, scratches and road debris while adding a finished look to the wiper assembly.

Replaces missing or cracked OE caps without tools

Each cap measures 32 by 39 by 17 millimetres and installs by pressing directly onto the existing wiper arm end. The change is worth it when the original cover has fallen off or split, leaving the nut exposed to rust that can seize the arm to the shaft.

Durable plastic holds shape through weather cycles

The moulded plastic resists cracking in freezing temperatures and does not deform under sustained summer heat. It maintains a tight friction fit over months of vibration, car washes and temperature swings, so the nut stays protected for the life of the wiper arm.

Questions about this item

Will the 32x39x17mm cap snap onto my rear wiper arm nut?

Yes — the cap is designed to snap directly onto the rear wiper arm end covering the nut on the listed Buick, Cadillac, Chevrolet, GMC, Hummer and Pontiac models.

How do I install the cap without breaking the plastic tabs?

Press the cap straight onto the arm end until the internal clips engage; forcing it at an angle is the step most people get wrong and can crack the plastic.

When should I replace these black plastic covers?

Replace them when the clips no longer hold the cap securely or the plastic shows cracking from UV exposure and temperature cycles.
