SUNROOF ANGLE REPAIR KIT SEAL MERCEDES W126 W463 A126‌7801512

MERCEDES-BENZ S-CLASS (W126, C126) · G-CLASS (W463) · 1979–2018

This is a complete sunroof lifting angle repair kit with seal for the Mercedes-Benz S-Class W126 and G-Class W463. It rebuilds the lifting mechanism that tilts and slides the sunroof panel, replacing the worn die-cast and plastic angle brackets and fittings that crack and seize with age and cause the roof to stick, bind, or sit unevenly. The kit also includes a new EPDM perimeter seal to stop wind noise and water leaks. Together these parts restore smooth, quiet, watertight sunroof operation without sourcing each component separately.

FITTING NOTES

WHY THIS MECHANISM FAILS
The W126 and W463 sunroofs are now decades old, and the lifting angle brackets and fittings that raise and guide the panel are made of die-cast metal and plastic that crack, wear, and seize over time. The result is a roof that binds, tilts unevenly, slides roughly, or jams. The perimeter seal also hardens and shrinks, letting in wind noise and water. This kit supplies fresh lifting components and a new EPDM seal so the whole mechanism can be rebuilt rather than replaced.

WHAT TO CHECK BEFORE YOU BUY
Confirm your vehicle is the W126 / C126 S-Class or the W463 G-Class and that your fault is in the lifting angle mechanism and seal rather than the motor, cables, or cassette tray, which are separate parts. Compare your old brackets to OE A126‌7801512 and A126‌7801612 and the seal to A126‌7800098. The W463 G-Class used this style of mechanism over a long production run, so match your parts to the kit before ordering. The seal section also corresponds to the W140 seal if only the seal is needed.

PROFESSIONAL INSTALLATION NOTES
Accessing the lifting mechanism requires dropping the headliner or sunroof cassette from inside the roof, so allow time and work methodically. Replace the lifting brackets and fittings on both sides, lubricate the mechanism with the correct Mercedes sunroof grease, and seat the new EPDM seal evenly around the panel so it compresses uniformly when closed. Cycle the roof several times and check for even tilt, smooth slide, and a watertight close. This job is best handled by a technician experienced with these sunroof systems.
