Occasionally, and unpredictably, I hear and feel a thwang and snap
sound from right rear, usually when making a turn.

CV joints and shafts were replaced last year, but have very few miles
on them. EMPI brand (I'm not looking for a "What you shoulda
bought..." beating, just some help with a problem. Shocks are over ten
years old, springs original, and probably the bushings, too.

What tests can I do to diagnose the problem? How much left-to-right
play in the spindle is normal? Any? Could the joints have been
incorrectly installed? How? Is that correctable?

I added grease recently, using a nozzle under the lip of each boot.

All advice much appreciated.
