[R Broberg]

Cody,
Try these.  BTDT most of this more than once.

Most of these torques assume new bolts and nuts

Strut to arm 66 Ft lb
Upper link to bearing housing (double pin with single bolt) 30 ft lb
Stut top nuts 15 ft lbs
Top mounting bracket large nuts (5) 74 ft lbs
Front upper rear control arm, inner end nut 37 ft lbs + 90 degrees
Front upper front control arm, inner end nut - that is one of the 5 above
Lower tapered pin end of front track control arm (has strut connected) at
wheel bearing housing 92 ft lbs
Other end (inner) of track control arm (front) 55 ft lbs + 90 degrees
Guide link (rear lower arm) inner end 55 ft lbs + 90 degrees
Guide linke (rear lower arm) outer end (at wheel bearing housing) 74 ft lbs
Short link upper nut 30 ft lbs + 90 degrees
Short link lower nut 66 ft lbs

Axle bolt 140 ft lbs + 180 degrees - 

Good luck!

I'm really thinking it's about time to buy a Bentley for the A8q.

Before diving in to the timing belt job I decided to put the car on  
the lift and check for other serious money pits. In particular I had  
noticed a very faint rattle/clunk in the right front corner that I  
wanted to check out. Turns out it's time for a control arm party!  
Right front wheel lower rear arm is amazingly bad, and I've already  
got one to put on. Both right front upper arms are also slightly  
loose. Left front wheel upper rear is the only one on that side. Then  
it's also got a bad CV boot on each front axle.

So what I'm after are torque specs for the following:
All 4 control arms on both sides and both ends of each arm.
