R107 Door and Window Seals: Replacement Guide

Wind noise and water leaks on an R107 usually come from aged seals. After decades, the rubber hardens, shrinks and cracks. New seals make a big difference in comfort and help prevent rust.

Which seals leak

  • Door seals on the body opening and on the door.
  • Window seals, including the inner and outer window scrapers (beltline seals).
  • Quarter window seals behind the doors.
  • Seals where the doors meet the top, both the soft top and the hardtop. See hardtop seals.
  • Windshield seal. See windshield replacement.

How to find the leak

  1. Close the top and the windows.
  2. Have a helper run water from a hose over the suspected area while you sit inside with a flashlight.
  3. Start low and work upward.
  4. A dollar bill test also works for door seals: close the door on a bill and pull. Little resistance means the seal is not sealing.

Seal kit contents

Seal kits for the R107 often include door seals, quarter window seals, window scrapers and the seals between the top and the windows. Contents vary by supplier; check what is included. Quality varies, so buy from an R107 specialist.

Removal

Door seals are held by clips, a channel or adhesive, depending on position. Remove carefully and note how the old seal fits. Window scrapers may require removing the door panel. See door panel removal.

Adhesives

Use a weatherstrip adhesive made for automotive rubber. Clean the old adhesive completely and apply a thin layer to both surfaces. Too much adhesive makes a mess and can stop the seal from compressing properly.

Window adjustment

New seals often require adjusting the windows so they meet the seals properly. The R107 windows have adjustment points for tilt and height. Adjust the window to close against the top seals without forcing the glass. Many owners have the adjustment done by a specialist.

Cost

A full door seal set is moderate in cost. Labor varies, especially if window adjustment is needed. Doing it yourself is possible with patience.

Quick answers

  • Can I restore old seals with a rubber conditioner? It helps slightly but does not fix shrunken or cracked seals.
  • Why is there wind noise at speed? The window is not meeting the top seal properly.
  • Do new seals fix all leaks? Usually, with correct window adjustment.
  • Should I replace all seals at once? If they are all old, doing them together is efficient.
