    Steering Feels Weird when Wheels are cut ALL the way.

    When my wheels are cut all the way left or right as if I'm driving around in a tight circle with my car the traction feels weird and it feels like the steering is making a slight noise. Maybe it's a quattro thing because it reminds me of the same feeling I got when I used to put my old Jeep cherokee in All wheel drive and tried to make tight circles or cut a super sharp corner. I relax a on the angle of the wheel a little it feels fine again, it's only when the steering wheel is all the way left or right while I'm moving. Normal?

    This is normal on the B6/7. The tires are actually grinding. My understanding is that it has to do with the front differential. This is one thing I love about the B8.5. No more of this stuff. Smooth as butter when making tight turns.

    I wonder if I'm doing any damage if I ever have to make a quick fast turn like this?

    Don't worry. I sold my S4 with almost 80k miles and no issues there at all.

    Its quattro, your doing nothing wrong. i thought the same thing when i first got the car. If you read the manual it actually tells you not to hold it there for more than 15-20 seconds. Dont know why but dont worry about it.

    Mine slightly judders at continuous hard full lock. I also have some power steering pump noise. I keep jacking it up and cycling lock to lock with the cap off and letting the bubbles disperse (overnight) but still everytime I bleed it, there's more bubbles! Filled for 10mm above max line when warm as well, just flushed with new fluid, febi mineral.

    I've always heard turning at full lock is hard on the steering system, especially in 4wd vehicles. So I try to avoid turning like that, but it shouldn't be too much of an issue. You're just putting a bit of pressure on the system, while putting a rotational force on the wheels. Think about when you use a swivel extension on a socket wrench; the closer you have the swivel to 90 degrees, the harder is is to turn. Now think of that swivel extension as your cv joints.

    I hardly need to cut the wheels that much but it's just something I noticed. I figured it was because of quattro but wanted to make sure. At least now I know to try to stay out of those angles as much as possible.

    Center differential binds a bit when the steering is at lock. The owner's manual even mentions that it is normal operation.

    Odd that my 06 A4 with 136K miles has never had this issue (that I know of) yet my 07 S4 at 90K miles does...

    This happens to me a lot when turning into driveways and such or busting a u-turn. Does this have any negative affect on tire wear?

    I think I experimented and when ESP is off this doesn't happen.

    Think its bad now? Put in the 4:1 center diff. Makes it MUCH more pronounced. Totally worth the it though, i have 0 understeer. Looking forward to the LSD going in next

    I just did my first oil change after getting my car back from an engine sway some months ago. My car like shit until I changed out my oil, and even the feedback I was getting when cutting my wheels is not even noticeable. The 4:1 center diff...I'm going to look into that!

    Exactly. The center differential attempts to equalize the rotational speed of your four wheels, and struggles to compensate at slow speeds when at extreme turning angle. It's just quattro; sometimes you may even hear a noise like a foghorn in this type of scenario. The problem is lessened when you speed up. Moral of the story, avoid these situations, as it places additional wear on the center diff. Remember that you can't tow a quattro with two tires on the ground for the same reason: when all four wheels are not rotating at the same rate, quattro torsen diff suffers greatly, and will burn out if hitch towed with two tires on the ground. The experience you are having is similar to this, to a lesser scale of course.

    When you are turning slowly at full turn, the difference in rotational speed of your other wheels compared to the inner wheels, at slow speed, is much greater proportionally, to the same full turn at higher speed. Thus, you'll see this during slow-speed full turns versus cruising speed full turns (if you can manage that, like doing spinnies or drifting at speed, you will not hear the center differential groaning; you risk damaging your steering pump instead if you hold at full turn for too long)
