Help diagnose an issue?
Howdy!
I've got a 997 TT cab, 2008, 37,000 miles. After having some work done (maintenance per manual), it's developed some symptoms I need help pinpointing.
When backing out of my garage, while the wheel is angled significantly, the car was "hopping" a little upon clutch engagement. I didn't think much of it the first couple of times, because I thought I was simply hitting a seam in the concrete, some small debris, etc.
Fast forward a week, to the day I've had the first long drive since the maintenance (150 miles). Pulling back into the garage with wheel sharply turned, the car bucks significantly when clutch is engaged. I try the same in reverse, and it is the same. I do a complete walk around, to make sure it isn't some dragging trash or a loose body panel. Put it away,
Today, I take it a couple of blocks to an empty parking lot, so I can observe the tach while recreating the issue. The engine is not cutting power, resulting in the hiccup.
Park it in the lot to do another inspection in daylight, and the driver's side

... wheel has very thick, sweet smelling black oil dribbled all over the interior rim surface.
Now, I did have my front differential oil changed during the maintenance. What should I be checking? Is it possible the mechanics have screwed something up??

Is this a "new" car to you? Cold weather? Performance tires or snows?
This is pretty common with the 911's suspension geometry.....and probably normal.

Of course!

Thought of this too, and it isn't... Wish it was! It happens even when the wheel isn't fully turned in one direction, and only when the clutch is engaged.

Anyways, to answer an earlier question, I am running performance tires (live in Texas [which makes me wish there was a GT2 cabriolet...]).

Bummer, I'm not an expert on these cars in any way, but I know cars, and oil on your rim like that isn't normal, I'd get it right back to the servicing dealer if you can. BTW, if you screw up a post (a common occurrence for me) you can go back and edit or change it by clicking on the edit tab on the lower right of the page. Good luck with the diagnosis and fix.

I don't think it is. It only just developed, and the associated oil leak certainly can't be normal! I assume it's a problem with the four wheel drive system... Though I suppose it could be the oil leading up to the front radiators, but it looks lots thicker than engine oil, and doesn't really fit with the hiccuping symptom on clutch engagement.

It is normal for the front tires, that is the inside front tire, to scrub or skip/slip when the steering wheel it turned full lock and the car backed out or of pulled into a parking space.
It is easy to see why if one takes the car to an empty lot and turns the steering wheel full lock and then shuts off the engine and gets out of the car and views each front tire. Approx. one half the inside tire's tread face will be off the pavement.
Since this tire is loaded the least in a turn and has to follow a different radius than the outer tire it will skip/slip. The behavior can be quite unsettling to the unsuspecting.
However, the fluid leak is not normal. I do not think it is differential fluid as my experience is this stuff is anything but sweet smelling. It could be CV bearing grease but I do not recall ever coming across any sweet smelling grease either.
This leaves anti-freeze/coolant or perhaps Pentosin (power steering fluid). Both of these are water soluble so some on your fingers and then in some water should have you knowing the answer to question is the stuff water soluble answered in no time.
Or get the car back to the shop pronto. Whatever it is will be best looked at with the car on the lift. If the front diff is leaking (my 03 Turbo's front diff axle flange seals started leaking a while back) it will be immediately obvious. The power steering rack and lines can be checked for any leak sign and the hoses/fittings and radiators and radiator areas can be checked for any leak sign.
