Strange Sound from rear wheels

[gdwyer]

There is a strange 'doppler' noise coming from my rear wheel / axle that is now louder than the engine ( think pod racer scene from Star Wars episode I )

It is a 99 2.5l Boxster.

What could it be? Ive had the wheels rebalanced, and the tyres are only 2 months old?

Wheel bearings?

Check to see if you have a huge rock stuck in the treads, or worse, a screw or something.

My guess is rear wheel bearing part # 999-053-041-03-M34 Manfactured by "FAG" .......or a pod racer is chasing you.

Take a look at the CV joint boots as well. If the boots are cracked and the joints have dried out, thay can make that type of noise.

An easy way to check if it is the bearing is find an empty quiet parking lot, turn off the radio and roll down the window cruising at about 20 to 25 mph swerve side to side if you hear that moaning noise get louder and softer as you swerve in opposite directions it is you bearing. The side where you swerve and hear the noise is most likely the bad side. I had a bearing go bad at about 35,000 miles, part was cheap less than 50 bucks each, but very labor intensive. Must remove the hub and have the bearing pressed out and new one pressed in. You will also need the tie rod tool to remove a couple of tie rods...
