I found the driver side sway bar link end was touching the lower control arm where it is mounted (metal to metal). End link was touching because the sway bar had slid to the driver side and was no longer centered on car. I loosen (no need to remove end links) the mounting nuts on the end link that connects to the bottom control arms and sway bar, then using a crow bar I centered the sway bar. Tighten end link nuts tight. The end link does not touch control arm anymore and there is no more noise from the driver side or passenger side when I go over bumps or turn left going over bumps.
