If you have experience, you can feel .020. I'd be prying a bit with a long screwdriver or rod to put a little pressure on them.
I did not have fancy equipment. I found vibrations by first bringing engine up to highway speed in neutral. If no vibration, then the engine, flywheel, damper pulley and accessories were probably OK.
Next step was to jack up the vehicle and solidly support it on suspension as close to the wheels as possible, so the suspension was as close as possible to normal ride height. I would quickly bring the drive train up to speed and then take my foot off, reversing the loadings. That would tell me if the vibration was caused by worn U joints, a bad pinion bearing, or out of balance tire or bent wheel.
If I did not find anything, I would remove wheels, put lug nuts on backwards to secure brake drums or rotors and try again. That would tell me if a drive shaft, or half shaft was out of balance.
