Took it apart again, no serious signs of wear (it is Mercedes) disassembled, removed all the lube, put it back togeather dry, put it in the door, QUIET, no noise works like new. Maybe we are oiling parts that should not be oiled, forget the WD-40 take it out and soak in a wax/grease remover. Hope I am correct, I'll leave the cleaned up part in the door and see how it goes. One final note don,t try taking the door check apart unless you have a bench vice to compress the springs to get it reassembled |
I'm glad you brought this up. Whenever I tried to lubricate my check straps with WD-40 it seemed to make it worse just as you found. It wasn't until they were replaced that my problem went away. I looked at the old door strap quickly and thought it was the ball bearing part that wore out and needed replacing but maybe you found something else.
Please keep us posted.
BTW, when I was test driving SL's prior to purchase I found that six of six cars had a noisy driver side door check strap in addition to the one I purchased.
