A cheap workaround, I was not happy with just manipulation of the ball joint to take the squeak out (i.e., FAST and CHEAP GOOD.) Turns out this is a latent design defect so I've ordered performance replacement parts:

A solid aluminum part with larger area ball, the casting covers the ball joint with a water shield and weights less.
I ordered from EVANNEX because they have free shipping until June 9. Upon registration, I also signed up for the $20 discount only to learn it has a 7 day window. I also noticed shipping is deferred until July. Regardless, I bought the right and left kit and will replace both control arms when the new parts arrive, $341.27.
Anyone know the Tesla part cost? Has Tesla redesigned theirs to solve the drain water, contamination problem?
