That's a great price!
It's the things you can't see unless you take it off that'll bite you when you least expect it (just ask Slakker)…

Yep, i just replaced those on mine, one of the most common causes of noise on 996/7 986/7. I just posted the kit for all those do can't or won't do the diagnostics or are chasing there tails, pulling their hair out trying to find the noise.

I haven't bought anything from them, i had just saved it in my watched list because it was such a complete set and very frugal price. This guy on Rennlist had good things to say about the price saving him 4k over Porsche price in a Cayenne drive shaft and suspension parts, and said the quality was good.YMMV

I had the same issue with my 996tt. I replaced strut, link, bearing etc. when I was shaking the car I heard the rattle from the fuel sender top.
Please check that.
I bought a used one for $10 and opened it to find this.
It appears the ball can get loose in the cage. Why such a heavy ball in the vent section in don't know.
Can I run it without the ball?

Once put together properly, I don't see the ball going anywhere. It serves a purpose...

I would imagine that ball will shut off the fuel from entering the tank vent and engine if the car flips upside down.Remember depending on a lot of variable, a fuel injected engine will run upside down for quit some time possibly. It's one of many safety devices.

Got it. That make sense. The ball fits into the cage and the cage fits into the cup. The cup fits into the base of the sender unit and the top is side on. I noticed there was a gap between the base/stalk of the unit and the upper cap. My guess is the weight of the ball coupled with vibrations wear at the three thin plastic pins that hold the entire unit together. When I reassembled the unit, only a very slight noise could be heard. Next I need to find a plastic fuel resistant glue.

Ok. I'm at my wits ends.
Sway bar link, strut bearing, strut, strut bearing even the ball in the fuel sender(huge improvement) all changed and there is still a knocking noise from the front left over small bumps. Tie rod is tight ball joint tight. Car only has 35,000km.
What else can it be?

Drop links? Wishbones/Tuning forks? There are lots of parts and almost all of them include either a rubber bushing or or some sort of rotating joint (i.e. ball joint). If you haven't replaced the "coffin arms" or "tuning forks" I'd start with them. Good luck

Tuning forks. Just replaced mine. On inspection the rubber was fine but when I moved it I could feel a clicking or catching. Fixed my clunking issue.
