An intermittent clunk/knock from passenger side
 

Hey all,
My 79 911 developed a knock/clunk from the passenger side and here's the symptoms.

-passenger side
-thought it was from the front but not completely sure
-tempo of the clunk coordinates to the speed of car not rpms
-turning does not make it clunk
-on a drive to Lowes, when I left the house it was not doing it but on the way back home it was. ???
-seems to happen after driving a while
-can make it come on or louder if accelerating and will quiet down on decelleration
-took the front passenger wheel off because there seems to be a touch of play when wiggling the tire and wheel around (like the wheel isn't tightened down)
-tried to wiggle again by grabbing the brake disc but couldn't find the same play.
-tightened lug nuts
-stock suspension and all original as far as I know.

What am I looking at guys and girls?
Thanks.

Check your front strut. It might be time to replace it

What would I do to check it?

This may be on the right track. I chased a clunking sound for months only to finally remove my passenger's side rear shock (a Koni that was only a year or two old) and found that it was toast. I could easily compress it by hand. I replaced the shock and the clunk went away. I didn't associate the clunk the bad shock at first, but evidently that was the problem.

Possibly worn sway bar bushings. It took me a long time to find this on my car. The clunking occurred when cornering and when going over speed bumps. It stopped when I disconnected the drop links.
