I'm having the rear control arms replaced by a local shop (I supplied parts) and they just called and said there's 2 upper arms. I don't recall seeing 2 when I was trying to replace the lower and pelican doesn't mention 2 in the parts section. Is it possible they are looking at something other than a control arm and mistaking it for one? This is on an '06 CS Ti.

 

there are two. I disconnected mine to change out an axle a few weeks back.

 

Good question. Parts 1 and 27 are both upper control arms on the rear suspension.
According to
http://www.autoatlanta.com/porsche-p...=95533104710#a
1 is the Wishbone upper rear (driver side)
27 is the Wishbone upper front

Also, 6 is the track rod, etc.

 

Thanks for the replies and the diagram oldskewel. I'm having them go ahead and replace the parts I've supplied and I'll do the others in a few weeks. May have to redo alignment but that's no big deal.
