Skipping steering wheel / tire fully turned

[Reset]

My 996 C2 has a strange problem when the steering wheel is turned fully till it locks either left or right. When the car is not moving, the wheel will hit the end of the rotation and all seems fine. However when you start to move forward or reverse, the steering wheel / tire starts to skip. Like the steering wheel + tires skips back, then it tries to catch itself back to the original position. Im very scared to turn the steering wheel fully when i make turns because it seems like Im hurting something. Has anyone experienced this before? any ideas?

Does it feel like your tires were rolling over small bumps?

I have experienced that and have been wondering what the cause is. I thought it was the uneven surface in the basement parking lot, then I tried it out at an open lot elsewhere, and it felt the same, except it was less obvious.

I have a C4S, so I thought it could be due to the AWD...? But I see you have a C2.

My turbo does this as well. I just don't turn it all the way now!! :) I just thought it was the front tires getting dragged around by the rear tires. It is especially bad if the front tires seem to be on a slick surface (sandy parking lot).

yea its exactly what its like.. rolling over small bumps. It just skips at the lock of turn left or right. I would think its the AWD doing it too if only mine was AWD! Very strange... I try not to turn the wheel all the way too. Wonder if anyone ever got a tech to look at this to figure out what the cause.

This is discussed here a couple of times before, do a search for more detailed info. It's a normal phenomenon in colder outside temps. called "Ackerman effect" and has to with the geometry, nothing to worry about.
