The guys at the shop didn't seem to think it was the bearings though.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have an 07
Cayman S
, and recently I started hearing a scraping/grinding noise when I turn to the left or during a u-turn. It's only to the left. I took it into the shop and they couldn't find an issue, however it wasn't a
Porsche
shop. He said they checked the control arm and bearings. I have checked to make sure the wheel isn't hitting anything. I'm at a loss at the moment. Any ideas?
Might be a wheel bearing. Probably front right-hand side given your description. Turning causes the loading to change vs driving straight ahead.
To replace the wheel bearing you have to first remove the upright from the strut, lower ball joint, and tie-rod joint. The wheel bearings are a sealed double-row assembly that must be pressed out/in after warming the upright; I think 180 degrees F. There is no adjustment or re-lubrication option.
So here is what I've found so far. The rear brakes are kind of low, so the brakes idea seems like it could be feasible. Not really sure how low brakes would cause grinding during turning while not hitting the brakes. But it's an idea. There isn't anything hitting the tire, so I don't think it's that. And the wheel bearing is still on the table. The guys at the shop didn't seem to think it was the bearings though. Any other ideas out there? I may change the rear pads and rotors since they seem low anyway and start there.
It could really be rust on the backplate of your rear
rotor
for example.
I had the same symptoms on my Honda. Taking the wheel off, I could grind the rust between the rear of the
rotor
and the backplate, and the noise was gone
All of the above advice is sound. However check the brakes ducts which may be hanging low. If you did not purchase the car new, there may be GT-3 ducts which are a bit larger and can scrape on sharp turns or on drive ways. Best to add cable ties to better keep them in place.
Had a similar problem awhile back, long story short, it was a stone stuck between the brake
rotor
. It was an awful sound and only when I turned right.
My wildassed guess. Ex SO had a late 80s T Bird that did the same thing. Turned out she had a lower ball joint that was worn. Just enough wiggle that the inner edge of the
rotor
would scrape the edge of the lower control arm on turns.
I am having the same problem on my left rear. Scraping sound only when turning right.
My thoughts have been:
1) wheel bearing - I opened the rubber boot and repacked with new grease. No change to problem.
2) Concerned that sway bar or something is rubbing under load.
3) I have not yet checked the brakes but will do that tomorrow.
Let me know what you guys find. I could use the solution.
Update: So I bought new brake pads and rotors for the back because they looked pretty low. When I went to take everything apart a small chunk of metal fell out. I replaced everything and found no other issues. I still had the same scraping without the grinding sound. Come to find out it was the dust shield bent in on the very bottom touching the
rotor
. Literally the only spot of the dust shield I didn't initially look. Luckily those pads were really low or else I probably would have been more upset about replacing everything than I was. I am going to assume the scraping was the dust shield being bent in and the grinding sound was that chunk of metal that was caught in my braking system possibly between the
rotor
and dust shield.
I know this thread is old but my '14
Cayman S
(22K miles,
LSD
, 6MT) just started making a similar noise when making a tight left turn. Sound seems to be coming from the rear wheel driver side. Any updates on what may be causing this?
I'd venture to guess 9 times out of 10 you hear scraping like this in a turn, one of the the front fender liners is broken and the tire is rubbing it in a turn. They seem awfully fragile; feels like I'm replacing one or the other every year.
Well, brought the car to the dealer and they found a stone lodged between the brake disc and wheel carrier on the left rear wheel. With large wheels and soft
tires
, the
Cayman
throws a lot of rock and debris around the wheel wells. So, if you have an intermittent, rotating scrape or squeak, could just be a rock.
