Ever suspect the front differential? I'm not familiar with the C4 but I'm sure the setup is the same as an Audi Quattro but reversed. When was the last time the fluid was changed?

I got my car back.
The grinding is solved.
They replaced the transmission mount bushings.

Whilst there he showed me the drive shaft coupling was going to fail imminently so they replaced the drive shaft too.

Total bill $1,760 including parts and labor.
I was quoted $1,600 by a local indy but I really like my dealer and service team at Herb Chambers Porsche.

I am finding increasingly close pricing between indy and dealer btw...

Glad your dealer fixed your problems, and it's nice to hear something positive about the Porsche dealer.

I'm with Gregg.........gotta be the right headlight...

I think when it comes to small, generally cheap parts (bushings, couplings, etc), going to the dealer vs. an indy makes little difference, since both charge $$ for labor. When you start replacing larger more expensive parts, the dealer charges more every time!

Umm...I actually decided to not change the headlight level sensor...and noise is gone...

So here's the repair order.
I am surprised that the transmission mount and drive shaft are both 997 parts...

Glad to hear you had a good experience with Herb Chambers. Did you bring the car to their Boston location or Burlington?

roadsession

Boston - they have different techs - one dedicated to air cooled and another dedicated to water cooled.

Stringy

Roadsession, your post gives me hope.
I have similar grinding on a RH turn - (https://rennlist.com/forums/showthread.php?t=986840&goto=newpost)
I will check my bushings.
Can you tell me which part on the bill is the main item in question - so I can see what it looks like and where abouts it is.

Part Number 99737503303, looks like its the whole carrier assembly with the two bushings installed..
