I cannot figure out where this vibration in my steering wheel is coming from. Tires are balanced, rims aren't bent, already replaced one hub. I do not want to drop my car off at Infiniti and tell them to figure it out. The vibration starts lightly at 55 an increases with speed. Sometimes it goes away and then returns at the same exact speed. I'm stumped. Anybody know a mechanic in NJ with plenty of experience working on 1st gen. Coupes? (05) automatic.

 

I wish l knew a tech also.check your compression rod bushings.Since you have your tires balanced sounds like the bushing.
