Cyclic thumping sound from rear wheel

[Kevin 1G Drummer]

I would say to check lug nut tightness, and if that doesn't fix it, it's most likely a wheel bearing.

Well I don't think I'll ever know for sure what it was. Emily took the car in for an oil change because I didn't have time before we left today, and they rotated the tires. They also said she needed new outer tie rod ends (I could shake the wheel back and forth a lot, it was bad), so we got some at oreilly's for 1/3 the goodyear cost and had that done too. Well now the problem seems to be gone, so who knows.

I know there was a vibration issue in the front end which I thought was a tire out of balance, but it was probably just the wheels shaking because of the bad tie rod ends.
