Wheel bearing noise?

[jmsgld]

01 986 Boxster S 68k.

Driving home from work, after heavy acceleration noticed a new noise, soft grinding coming from the front, sounds like metal on metal, quite quiet. Related to speed of car, not engine / gear. Worsens with heavy steering to R, lessens with opposite.

Sound like wheel bearing? How do I check?

Thanks, James

To check, you'd jack the car up and spin the wheel by hand, then narrow down the source of the noise. It might just be a stone caught in the brakes.

When I had a wheel bearing problem and checked, there was no noise when jacked off the ground. I changed various things but it didn't fix it. In the end I fixed up a contact microphone on the bearings, one at a time, and went for a drive. THat worked and identified the bearing straight away.
