I have a 04 g35x. only mods so far is a ztube and knn panel filter. the thing is i have really bad road noise coming from the front driver side. i put new good years all around and the noise persists it starts at low speeds. below 20 and continues to get louder the faster i go. rattles the whole damn car. if anyone has a CLUE as to what's up lemmeknow. btw I'm no noob to cars or nissan/infiniti, feel like I'm chasing

 

Have your wheel bearings checked out. Sounds similar to what I was experiencing - changed out both front wheel bearing and the noise went away.

 

Two possibilities on the noise you're describing, check your front tires for wear on the inside 1/4s. At one point the noise got so bad before I installed a camber kit (bought new tires) I couldn't turn up my tunes loud enough. Wheel bearings are another possibility but you should also hear grinding noises too. Both are easy to check...Gary

 

New good years Gary.

Op, raise the wheel up with the provided jack and rock the whee from top and bottom (hand on each part of the tire mentioned). If there is "play" then you likely need new wheel bearings.

 

Ran you problem through a friend of mine who is a Infiniti Tech @ Orr Infiniti in Shreveport, LA. He has seen this a few times and it is the bearings.

 

Awesome thanks for the input. payday ill put new hubs and bearings up front.

 

Damn I missed good years, had he posted Good Years I might have seen it! I quit using those **** tires when one left me stranded 70 miles from my front door! Ever try driving 60 max mph on the interstate 5 at midnight running a f'n donut tire? Check the wheel bearings...Gary

 

Probably wheel bearing. I'd reuse the old hub they tend to hold up. Bearing not so much.

 

I got the new bearing in yesterday. not the easiest thing to remove, aluminium and steel don't mix to to well. it was siezed up like no other. even with a mac tool hub tamer set and lots of pb blaster. cleand it up put the new one in pressed in the hub. wow. its like a whole new car. thanks for most of the input.

 

May not be that obvious. When my 3 wheel bearings failed, there was no play at all.

In order to diagnose, i had to take the wheel and rotor off and physically grab the hub and turn it. Only then could i feel the roughness.
