Finally back to the forum after rebuilding the last ABC fiasco, and now I need to replace the rear lower control arms.
I went to the dealer to get a full diagnosis of the car as well as fix the check engine light for the P048 secondary air injection malfunction.

Everything was fixed, but they also noticed that my rear thrust arms (control arms) were going bad. I'm ordering new ones made by Lemfoerder, but is there anything else I should be aware of or order to fully condition the rear suspension? Is that manufacturer good? Please leave suggestions, thank you!

Check the quick release coupling collar hasn't seized.

Check the level sensor link joints aren't getting stiff.

Check for play in the strut-top rubber bush, with the wheels in the air.

I'd also recommend draining as much dirty oil out of the bleed nipple as you can.

Checked all the arms and they seemed okay. Even the thrust arm that the dealer speculated was still good. I received the new control arms, but they hole didn't fit the specifications for the bolt so it is being sent back instead.

This time, I was thinking of just changing the bushing front and rear with Lemfoerder bushing kits. Would that be better? Has anyone heard anything about this brand? It's German so I'm assuming they may be a supplier of Mercedes OEM.
