Part Number: W0133-1778007
Notes: Main Arm w/ Airmatic Dual Control/Air Suspension Semi - Active (Code 489)
I ordered both rear control arms from this site. Be advised the control arm is a two-piece assembly with a pressed-in outer bushing. The two-pieces may rotate out of alignment but can be re-aligned using your hands.
Also, be advised you will need to deactivate the SBC and remove the brake caliper to remove the outboard bolt (which is a 12mm allen-head bolt).
When reinstalling the control arm, the hub has a press fit bushing that may not allow you to insert the outer end of the control arm into the hub; in that case, be prepared to use a flat file to remove *as little as possible* of the bushing at an angle that will allow the control arm bushing end to get started.
The rear control arms are very soft alloy; use only a rubber mallet when working with it.

Car slid during a sweeping left & the drivers rear clipped a curb. Broke the wheel + alignment is out (outside wearing of tire) + getting a vibration. Figuring that soft arm must have bent. Replacing sounds like a bit of a ******* job based on your description?
Thanks for the link

One day work and you'll have it done even if you take your time. Biggest PITA was having to lower the exhaust to get to the toe arm bolts so I could remove the toe arm.
Read the info at the following link and pick and choose what applies to your car. This was from my install.

Lots of pages because I also replaced the air springs at the same time but you'll only need pages 3 to 12 unless you plan on aligning it yourself. Don't forget to disable the SBC before removing the caliper. And you're going to need 1/2" drive breaker bars to loosen some of those bolts. If you stay with the stock inner bushings the inboard bolt won't be too bad.
Note the inboard bolt uses a triple-square spline bit. Xentry or DAS recommended to make this job easier.
I would recommend junking the stock rear toe arms and installing a set of Shardul's UPD toe arms. Makes setting the rear toe much easier.
