2004 I 35 road noise

[Edzo]

My 2004 infinity I35 has unbearably loud road noise. My 2002 Infinity I35 is quiet. They have the same tires. THe 2004 noise was always louder than the 2002 but seems to have gotten worse. The car does not display any performance or handling problems. I have Goodyear Eagle RSA tires on both. Is this a serious mechanical or safety issue? Any suggestions? Is it just wind and vibration? Can it be fixed?

Difficult to tell what it is without hearing it. Is it coming from all 4 tires?

Wheel bearings?

[Edzo]

Donot really know what is causing noise. The car is fine when started and the noise gets louder as you accelerate and maintain higher speeds. It is more like a droan or loud hum than a sqweek or squeel.

Wheel bearings.

Will check out wheel bearings next week and update you. Thx for the post.

A wheel bearing typically changes noise as you turn, so perhaps it might get louder when you turn left compared to turning right, or vice-versa...

[Edzo]

Car is relatively quiet when started and at low speed. When accelerating it gets loud. Havent noticed a difference when cornering. Will check it out tomorrow. Thx for the info.

Thanks for the feed back. I finally brought my car in for a test drive. Definately front rt and lt wheel bearings and hubs. The mechanic also noted the front tires purchased recently were installed wrong. Unidirectional tires were installed reversed on the front of the car. Nice going GOODYEAR.

I suggest using a quality NTN, NSK, or Timken bearing if possible or any kind of heavy duty one if you plan on keeping the car more than a couple years. OEM is fine too.

I had cheap bearings on my Cadillac that went bad after just 13,000 miles. With the 35,000 miles I was putting on that car each year, it didn't take long to go beyond the crappy 12k/12mo warranty. I was out west in the middle of nowhere when my front end started roaring. Thankfully, I managed to make it all the way up the coast from AZ to CA to OR (getting louder as I went on) and found a competent shop to do the replacement with a better bearing.

Wow...that's a pretty solid fail. Don't go back to that tire shop.

Had dealer do the work .. replaced WB and Hubs .. super expensive for an old car but then again they gave me a loaner for a few days and didnot charge to correct the tires installed improperly by Goodyear. Thx everyone for their information. Sorry I was late to respond but my computer crashed while I was in travel status for a week. Just now catching up.

Glad to know it worked out for you! How has it been since the repairs? Is it still louder than the '02?

[Edzo]

Sounds great - virtually the same as 02 no real noise.

I have a 2004 G35 Coupe and I upgraded the rims to 20'' and it drives rough and once I cross over 65mph my gear stick vibrates this was not happening before I upgraded the rims need some help here thanks

[OriginalWheelman]

It rides rough cause your tires have no sidewalls. As for the vibration, your wheels are probably out of balance and the vibration is coming up the driveline.
