[s-cars] Turning shudder 2003 S8

[Stafford, Kenneth A.]

Any BTDT's with my problem?  Under high power, my S8 has a bit of a shudder when in hard (ie full-lock or near full lock), slow turns.  It is absolutely asymptomatic in any other condition.  There is no obvious CV clicking at full lock and no bearing howl at any time.  Does the same with or without ESP on (of course, it is when I'm trying to light up the tires that is does this!).  Thanks.
