Both of the lower arms at the front were replaced in September and the rest of the suspension was given the OK.

When I turn right using full lock there is a noise that seems to come from the left front wheel area.
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.

When I turn right using full lock there is a noise that seems to come from the left front wheel area. Does anyone have any ideas? My car is a 997 turbo if that helps at all.
Thanks,
Pete
I had an eerily similar issue. It turned out to be the wheel weights knocking against the brake duct housing on the inside of the rim when on full lock in one direction.
I had same issue when I picked the car up when it was new from West London OPC. Turned out to be a tyre had been incorrectly fitted at factory and there was big chunk of the inner lip missing. Hardly received an apology from West London Porsche!
Could be several things, something simple like a loose/broken wheel arch liner or something worn such as a ball joint, suspension top mount or track arm. You need to jack the car up and asses any wear...

Could be a number of things but the most common reason for the noise at full lock -- in either direction -- is the inside front tire scrubs as one backs the car out (or drives the car forward). Cold tires, or old/hard (due to heat cycling) tires are particularly bad. I'm in my 996 Turbo in sub 20F temperatures and the relatively low miles front tires on my car make a heck of a racket as I back out of the hotel parking space.
You can get a feel for why the inside front tire scrubs a full lock by pulling into a parking lot where you have the room to cut the steering wheel full lock and then shut off the engine. Get out and sight how the outer front tire sits flat on the pavement while the inside front tire is about half way off the pavement.
If you hear noises at other times, not at full lock, there could be something else amiss and you need to get the car inspected.
Thanks for the quick replies.
I'll get the car in garage and have a look if anything is rubbing or catching. I'm leaning towards the wheel weights as the winter wheels were put on a month ago with new tyres and I started to notice the sound a couple of weeks ago. Both of the lower arms at the front were replaced in September and the rest of the suspension was given the OK. Fingers crossed.
