i hear airplane like sound from right side front over 40mph..... wheel bearing? or?

 

yes. I have been made aware that G35 go through wheel bearings... LoL

 

Yup. From the sounds of it. You can jack that wheel up and shake it in and out it shouldnt have any play at all.

 

Pretty sure it's the bearing. I ordered mine at eBay for $150 shipped.

 

Could also be a cupped/feathered tire, they sound a lot like a bad bearing.

 

The joys of G35 ownership. "Whats this noise?" Wheel bearing, the answer is always wheel bearing.

 

+1. Might also have your alignment checked. If your toe is out of spec it will accelerate the tire wear and can make a similar noise.

 

If your tires check out fine, def the bearing. Ive had to replace all of mine.

 

04 i am looking to get has 2 front bearings that are bad...very loud noise above 30 mph..also a little vibrating in wheel

 

thank you !!! def vibration in the wheel and my tires are ok,,, low on thred but OK,., alignment was done 4 months ago..... so that is not the issue,,, sound only comes out 35+mph

 

should i replace 2 fronts at the same time? replace the other when it goes bad?

 

when I had that noise I jacked up my car and I couldnt get any movement out of the bearing, so I changed the tires instead..

the noise was still there, so I changed the bearings.. quiet as can be, even though there was no play at all

I would do both of them.. the other one probably isnt far behind, plus it is a good idea to get your alignment done afterwords, and it is better to only pay for that once
