rear end noise
 

I am wondering about this wierd sound coming from the the rear passenger side. Sounds like a winding noise. It starts when i get up to about 30mph and just gets worse as i increase speed. I tried coasting in neutral, with the engine off and I still get the noise. I would like to know what is the best way to trouble shoot this issue, since i do not have the slightest idea what could be causing this.http://www.pelicanparts.com/support/smileys/yltype.gif

Wheel bearings? Road noise form tires?

winding noise?
 

Not sure what you mean by "winding" noise... do you mean whining? If so, then it could be a dry CV joint or something in your tranny.

I had a rumble from my rear (not that kind of rumble! and I mean my car's rear) this past spring. I thought the wheel bearings were going. Instead it was my tires.

If your tires are worn out, replace them. Or borrow a set of wheels with good tires. If the noise continues, then at least you've ruled out tires as the cause.

I have to agree with the tire thing, mentioned by Lucky. After my Yoko AVS-Sports got ~10K miles on them 245/45s on 9x16 rears, it sounded like a bad CV or wheel bearing. I got where I couldn't wait until they wore out.

Re: rear end noise
 

My alternator was making a loud noise prior to failing. Sounded like a high pitch whine which modulated with the engines RPM. You might want to give it a look.

Whinny noise
 

Thanks guys for the info. I really did mean whinny noise coming from the rear passenger side of the car. However I don't think that it is coming from the tire. The tires are Dunlops, and they are only about 6mo old. I am thinking now that it may be the bearings or something pertaining to the rear end.

Thanks

I think you're hearing a wheel bearing, but check it out. Could be tires too, but I think I would raise the car, shake the wheel to see if there's any play, spin the wheel to see if there is any noise. Prying the brake pads back will move them out of the way if necessary. I would then put the wheel on the ground, in gear, e-brake on, and make sure the big axle nut is tight. Tight means a LOT of torque.
