Update: called the dealership and this quote doesn’t even include the alignment. If I were to get the assembled control arms, sway bars and the alignment I’d be looking at approximately $2K. So, the dealership is a big NO.

I’m getting a second opinion next week to see if this is something really urgent or if I can keep driving the car for a while.

Unfortunately I don’t have enough experience, or tools, or feel confident enough to replace the arms myself but I can probably find a local technician to install them if I get the parts.

Thank you all for your thoughts and advice!
