: Loud road noise, passenger side front.... help!

Good morning all,

Recently I switched from my summer set up to my winter. What that entails is, 18inch rims, down to regular stock 17s with boring toyo tires etc... Seems simple enough yes?

Now as I was driving home, sad, as I had to switch! A very distinct sound had started to make itself quite clear, coming from my passenger side front wheel, its not a grinding, or a clicking, or a rubbing..... My 1st thought was, I have a BF Goodrich tire there (just dump luck, as I got a flat last year, and had it replaced and it was placed there when i switched last week) So I went to Shaw Saab, my local dealership and had it swapped with my passenger side rear, hoping that it was just the different tread pattern and type of tire that was making this sound.

Of course the sound is still there, and is quite disconcerting.... I have rev'd the engine while in neutral, and she sounds perfect... in what little i know about car's engines, this sound I don't believe is an engine "thing"

The sound coming from the right side gets louder as I accelerate, and is worse as i turn left, and the car rolls onto that side!!!

Hopefully this is something simple.. but anyway, thank you for listening to my long and drawn out description!! Hope you guys can help!!

Happy Holidays,

Coonsja

Sounds like a bad wheel bearing to me.

Does it go away/get softer when you turn right?

It is def worse when turning left, Its a little better when turning right. Why do you ask?

Could the camber of the wheel be off, and is now wearing the tire down unevenly?

Either a bad bearing or the backing plate behind the rotor got bent when they pulled those big heavy 18's off of it LOL. Check for backing plate clearance behind the rotor

My guess would be that it would be something on the right side. Probably a wheel bearing in the front or rear.

To aid a correct diagnosis, jack up the wheels and place your hands on opposite sides of the wheel. If you can rock the wheel back and forth (pulling with your left arm and then your right, not along the rotation of the wheel, but perpendicular to the rotation) it's probably the wheel bearing. You will hear the fammiliar clunk in slow motion... Check several wheels to make sure it's not more than one...

Front: http://www.eeuroparts.com/Main/PartDetail.aspx?id=5392493

Looks like you may need these for the front:
(3 of them) http://www.eeuroparts.com/Main/PartDetail.aspx?id=5125570

Definately one of these:

add another $250-$350 for labor...plus they'll probably mark up the prices on the parts...

Well after some prof opinions, turns out that my winter wheels, and stock toyo tires are just "crap" the sound is "sh#*$y tires! Certainly makes things easier! No need to replace a wheel bearing or 2 (at least for now)

Thanks for all the help and suggestions guys! Until next time!
