Our 2009 Mazda has been making "airplane noise" for a few weeks. I'm almost certain it's a front wheel bearing. (Noise varies with road speed, not engine speed, doesn't change when MT is dropped into N.)
I changed the driver's-side wheel bearing almost 4 years ago, and removing the hub from the splined drive axle was quite a challenge.
I had thought of trying to loosen up the passenger side at that time, but the wheel bearing was still quiet, and when the splined shaft is seized in, the removal process puts a lot of stress on the wheel bearing, pretty much setting it up for early failure.
So, here's my weird question ... if I backed the hub nut off a turn or two, and drove around a bit, would that be a reasonable way to loosen up the splined shaft within the hub? The hub nut would still be there to retain the shaft, but would hopefully allow the shaft to loosen up in the hub.
If this is stupid or dangerous, please let me know. Driving would be at low speed on quiet streets in my neighborhood only.
Thanks all for your input!
