Thanks for speaking up for some clarification. :thumbup: I actually typed in a much shorter, similar request that would have been post #2, but decided to delete it.
BTW, everyone, please note that diagrams are great, part numbers great too (for google purposes so others can find your great info months or years down the road), and also that
"rear suspension forward control arm" is far clearer than something like
"rear front control arm"
See the difference?
Also many of these arms have their own special names, such as the "guide link" there. BTW, my guide links are still truckin' along at 192+k miles.
Carry on.

Agreed on the nomenclature. This definitely helps! I still feel a little bit nebulous on what the OP goal is exactly. I've done pretty much everything suspension related on my SAV with the exception of a couple suspension components.

I'm interested because I will be changing the bushing to poly which is essentially a lifetime bushing. So the ball joint is likely to wear out before the poly if the poly ever does. The existing arms have about 60,000 miles on them, so they've got maybe 40,000 miles left in them. I have 250,000 miles on this truck and I am shooting for 350,000. That means those ball joints will need to be replaced sometime before I ever have to replace the bushing. Since the arms themselves are essentially a lifetime part and a poly bushing is a lifetime part I'm curious to know if it is possible to replace the one piece of the arm assembly that's not lifetime. Especially since if the ball joint can't be replaced I will need to order a complete new arm, press out the rubber bushing to install poly and throw away the rubber bushing. Along with throwing away a perfectly good control arm that comes off with the worn out ball joint. Make sense?
Adjustable are still available from Hardrace: https://hardraceusa.com/collections/x5-e53-2000-2006

From your link, those are the REAR suspension upper control arms. Between the two, they are forward and rearward. From my experience, it's not the bushings that go out in those control arms, it's the integrated joint. Back to what stephVA was inquiring about is, what is your goal? Are you wanting specific wheel alignment?
I think adjustable rear suspension upper control arms are way more costly and less permanent than just getting proper rear suspension control arm bushings. In addition, using the upper control arm adjustments changes the offset more than making the proper corrections on the lower control arm for the rear suspension. This might pose problems for wheel offset and fender alignment. This was my ultimate deciding factor for not choosing to go with the rear suspension upper control arm correction solution. Using a poly bushing type in the rear suspension lower control arm is more of a permanent solution as opposed to the upper control arms in my opinion.
As a side note, I've always been curious if these have been compatible with E53 rear suspension control arms: https://www.fcpeuro.com/products/bmw...ings-spc-72185
They are definitely more affordable if you're wanting the adjustability. And the E53 rear suspension is borrowed much of the other platforms that are listed in the compatibility tables for them. I dunno...but I wasn't willing to take the chance.
