Bentley Bentayga Rear Right Window Regulator 4M0839462

Restore the effortless functionality of your vehicle's rear windows with this Genuine Bentley Rear Right Window Regulator. This authentic factory-original component (4M0839462) is the internal mechanical assembly responsible for guiding and supporting the window glass throughout its travel.

Designed specifically for the passenger-side rear door, this regulator is built to withstand the weight of Bentley’s signature acoustic dual-pane glass. Over time, original regulators can suffer from frayed cables or cracked plastic pulleys, leading to "crunching" noises or a window that becomes stuck. Replacing your worn unit with this OEM assembly ensures perfect alignment within the door frame, maintaining the airtight seal necessary for cabin quietness and weather protection.

Pro Tech Tip: When a window regulator fails, it often leaves the glass unsupported. Mandatory: Before removing the old 4M0839462, use painter’s tape to secure the glass in the "up" position to prevent it from sliding down and shattering inside the door. Caution: When installing the new regulator, ensure the window glass is seated correctly in the mounting clips before tightening. Over-tightening the glass-to-regulator clamps can cause the tempered glass to fracture under stress. After installation, always check that the drainage holes at the bottom of the door are clear to prevent water from corroding the new cables.
