Newly installed check strap installed in the correct orientation clicks loudly. It's a Porsche part. The a pillar is in good shape and the door structure area where the strap connects is fine also. Any ideas on what this is or will it just take time the wear in?

 

"Wear in" is the first of the two phases of "wear out". "But it doesn't feel like my old one did." "That's why you replaced it!"

You can add a thin film of clear silicone grease to the strap to smooth the operation, reduce the noises a little, and protect the plating from wear. Do both top and bottom surfaces.

A handy waterproof clear silicone grease for stuff like this and the strikers and latches is marketed as "plumber's grease" at home stores like Home Depot, Lowes, Ace Hardware, etc. Comes in a little jar, gets applied with a small stiff-bristled brush, maybe an acid brush with the bristles cut off short. Then for me anyway the brush and the little container of grease go into a small ziplock bag, paper towel square wrapped around the end of the brush. Then I forget where I put the bag....

I use this in places where there's only a small chance of getting it in clothes in normal service. Where there a likelihood that clothes will come in contact, I use Vaseline since it will wash out with water. The downside of Vaseline is that it will eventually wash out with water from the area you intended it to work. Battery terminals get Vaseline so that normal heat will melt the paste and it will run down into voids with a little capillary action. Plus it cleans off easily when you service those terminals.

 

Fresh ones are clicky, it means there are actually detents doing their job. +1 on the grease, I like Superlube.

 

My mechanic (ex factory 928 master technician) said to use clear moly grease on them. A really thin coat does the job for months.

 

New will be stiff and have a notch sound, I've also see where doors were cut for larger speakers and that did make a big difference depending on what they cut.

 

The new door stops are very aggressive....much more than the original pieces were.

If the pin which attaches the door stop to the chassis has any slop, there will always be a loud click as the door stop snaps past the "detent" area.
