Pulsation/Vibration on Highway
 

Z seems to have slight pulsation/steering wheel vibration when on highway at 65+. My Nissan dealership looked at the car twice and resurface my brake rotors and reweighted my wheels and cannot find anything else wrong.

Anyone have any suggestions or know any good Nissan techs in the NJ/NY area that works on 370s that would be able to pinpoint the problem?

Any other details about the symptoms? Is it happening while braking, cruising, accelerating, or all three?

Have you changed tires recently? Have you done a proper alignment?

80% of the time most when cruising at 65 70+

Dealer checked my tires and said they were fine as well as alignment

balance....definitely sounds like a balance issue.

Probably a balance problem but could be alignment, bad tire, worn suspension, &c. Take it to a reputable tire/alignment shop and get them to check it out. Or it could be the pavement and road conditions - check on another stretch of pavement.

you need to check road force that simulates road condition on your tires. Good balancing machine should have it. Even tires at perfect balance with excessive road force/runout will cause shimmy at high speeds. Which nissan dealer did you go to? I'm from north jersey and just wondering
