Droning Noise - 911 SC
 

Hi Guys,

Car is 79 SC with new wheels/tires.

When I steer a BIT to the left (hardly at all) I get a loud droning noise from the rear end. This is whether the car is in gear under power or in neutral and coasting. If I turn the wheel a bit the right of center (or just about center), the droning noise goes away.

I'm really stumped, any ideas???

Wheel bearing :)

Or CV joint. Does it increase in each gear or is it constant?

Yup. The classic sign of a bad or loose wheel bearing. A total pain, but not the end of the world.

The droning sound changes as the speed changes, the frequency gets lower at slower speeds.

Is there a way to determine which side? i.e. if turning left (A bit) causes the sound then does that indicate a particular side?

Thanks for the help so far!

It could indicate a particular side but IMO this is something that when you do one you do the other.

Chew on that idea :)

Wiggle test?
