Hi guys! I'm having a steering wheel vibration problem with my 2010 G37 sport sedan. The problem usually occurs while driving over 60mph and stops when I'm over 80mph. Anyone have an idea as to what I should be looking for or where to even start looking to fix my issue?

 

Check tire balance and front axles

 

I've gotten countless tire balances, road force test, alignments and still have the same issue. I've even gotten new tires and rotors with brakes.

 

Check the wheels for runout. A bent wheel can cause vibration.

Is your car AWD? If so, check the front driveshaft (runs between the transfer case and the front differential).

Is there any play in any of the components of the front suspension? Are the front wheel bearings in good shape?

 

A malformed tire can also cause vibration at speed though it is normally felt at all speeds.

 

Hey OP, i had a similar issue, though mine was fine one day, took it in for oil and balance and then it started, so took it back multiple times to shop and it continued, so finally went to a diff shop and they said i have a tire that could not be balanced and thought it was due to inner tire rupture blah blah...almost bought a tire from them lol, but took it to another place and they balanced and car was back to normal, so yes, all the above are and could be applicable, but maybe just try another place for a balance etc..good luck, as i know it's aggravating

 

It is either tire balance or maybe your drive shaft needs to be "freed up". There is a TSB for some G's to "free up the rebro join in the drive shaft"
