Groaning, snaping and jammed door check straps are a common problem on the older models (up through 1995). This is primarily due to age and lack of lubrication. Newer models will soon start having similar problems. Rain water getting inside the doors is the big killer. This video will explain what to look for, the tools and supplies you will need and how to replace it once you get the door panel off.

Kent explains how to test if your check straps are not working properly, explains how the mechanism works but he does not cover getting your particular door panel off.

Related Repair Details NOT included: In order to replace the checkstrap the door panel will need to be removed first.
