Overview
The Crown Automotive Rear Window Seal, part number J5455398, is a rear window weatherstrip for 1974–1978 Jeep J10 and J20 trucks. The seal sits at the rear window opening and helps keep water and debris out of the cab.

Weatherstrip care and inspection
A rear window seal keeps water out of the cab by staying compressed against the glass and the body opening. Over years, the rubber can harden, flatten or split, which lets rain and road spray in around the rear window. Checking the seal every season helps catch problems before the cab floor or interior trim gets wet.
When replacing the seal, clean the window channel and remove old adhesive or debris first. Old residue can stop a new seal from sitting flat. Dry the surface fully before setting the new weatherstrip so it bonds evenly, and mark the start and end points so it aligns correctly.
Rubber seals respond to heat and cold, so keep them away from solvents and petroleum-based cleaners that can swell or degrade the material. A mild soap solution and a soft cloth are enough for routine cleaning. A silicone-based lubricant can help a seal slide and reseat smoothly.
- Look for cracks, flattening or gaps along the seal
- Clean the window channel before fitting
- Use mild soap and water for routine cleaning
- Check for leaks after the first rain
