Wheel wobble at 9 & 3 - suggestions?

Only front left - the most noticeable thing is that sometimes when I'm making a sharp turn at low speeds - pulling out of parking spot or something - it almost sounds like the wheel stumbles / judders / scrapes? It's hard to explain. I don't really get much rotational noise though when at highway speeds.

I think that is kind of normal for us with our wide tires, I've seen a lot of threads where folks with newer Porsches think something is wrong when they back out of a parking place and turn, and it feels like the tires are skipping, almost like driving over acorns or something.

I'm pretty sure I'm running correct sizes - 225 in the front and 265 on the rear on 18" turbo twists, but yeah the acorn analogy sounds pretty spot on. The play in the wheel is pretty significant though - but I would imagine that it would wobble at 12 and 6 too if it were bearings.

The track arm can be checked easily. Just jack up the front end and put on jack stands, remove the plastic brake cooler, remove the track arm bolt to the control arm center bushing and swing the track arm forward. You can then check for play. If yours is bad enough to "clunk" you will easily feel it. You can then visually check the center bushing in the control arm. Stick a large screwdriver thru it and move around looking for cracks or tearing. If no play then just bolt back up. no alignment required. You sure the clunk you're hearing isn't just due to play in the steering wheel lock side to side?

I'll double check, but I'm pretty sure I would hear it on the passenger side as well if it were the steering lock, no? I'll do the control arm test when I get a chance later this week - I was also alone this week so I'll have a friend wobble the wheel while I get under the car - I wasn't able to see much of anything by myself.
