The rumble underneath my car is driving me nuts. I’ve been chasing it down for quite a while. The Nissan regional service tech says it’s the control arms need replacement. The dealer wants $4600. Midas muffler wants $1800. Both of these estimates include wheel alignment.

This is a 2012 G37x I’ve already replaced tires, stabilizer bar, rack, and pinion, with multiple wheel alignment along the way. At this point, I really wanna find somebody who’s not going to charge me an arm and a leg. I live in the Troy Michigan area. Recommendations would be greatly appreciated guys.
