How to determine which wheel bearing is bad
 
1993 SSE-SC

Driving a 93 SSE with sonoma_zr2 mileage on the odometer today. I noticed a low pitch humming noise which I could feel and hear in car. It changed noise with pitch.

It looks extremely easy to change, how do I determine which one is bad?

get it on jack stands and put it in gear.

That won't have the bearing under load, and will tell you nothing.

Put it on jackstands and wobble each wheel in and out, up and down, from 12 and 6 and 3 and 9 o'clock. The bad bearing should be obvious.

You can also jack the front wheels off the ground and spin each wheel while holding onto the coil spring. You will feel a grinding in the spring on the side with the bad bearing

I would say just pick up a set of bearings anyway, it's time. There not that hard to replace.
