Product Details
WARNING READ CAREFULLY: Since Mercedes no longer makes rear door checks we can only obtain aftermarket front door check straps and modify them for use in the rear door. On some years these may not fit "perfectly". It has to do with the hole alignment for the attachment bolts (primarily on the door panel). You may have to take a round file and enlarge the hole slightly. This check strap also has two detents as opposed to one on the original. That can actually be an advantage. The check strap will work just fine. PLEASE DO NOT ORDER UNLESS YOU UNDERSTAND THIS.....
Failure of the rear door check strap is almost always caused by water washing away the grease, drying out the ball mechanism which eventually leads to failure as you can see in the picture below:
