Just reporting back with a report of some of the things that are
not causing the squeaking/creaking front end sounds:
- sway bar bushings and links
- lower arm bushings
It might be:
- Shocks
- Damper mounting bearing (top of strut under mounting flange)
Remaining suspects involve removal or replacement of front struts and re-alignment; not worth the effort and expense as far as I'm concerned, since suspension function, steering and handling seem not to be affected at all. I guess I'll just learn to live with the noise until the shocks need to be replaced.
