[A8] New to The List

[Jason Wilkerson]

Hi all,
  I have been a V8 Quattro owner for the past 10 years or so.  I recently upgraded to a 99 A8 Quattro.  Pearl over Navy interior.  In really great shape and I plan on keeping it for a long while.  Quick question - I recently replaced the whole front suspension with a kit (all control arms, inner and outer tie rods, etc), replaced the outer CV joints and brakes.  I also tightened the steering rack a little.  The 'creaking' has gone away and the car rides smooth and tight.  When the car is slightly in a corner and the suspension is just right there is a small 'Pop' from something under the drivers side - this sound was actually there before the suspension got replaced and I thought that would solve it - it did not.  I'm kinda leaning toward the steering rack, but I just am not sure.  All suspension bits are good and tight (and of course new) - the steering does not shake, has no real play in it.  Nothing obvious is broken or loose.  Could it be a motor
 mount?  Trans mount?  Subframe bushing?  Shock mount?  Anything else?  Thanks in advance and hope this list is as exciting as the V8 list has been for the last 10+ years!
