Fixing the front end squeak without grease injection

Over time, gravity settles the grease below the control arm, ball joint leading to a metal-on-metal squeak. I just fixed my front end, ball joint squeak without injecting grease or replacing the control arm.

Jack up the car; remove the tire, and; remove the clamp bolt. Then use something like vice grips to grab the ball joint shaft and squeeze the boot to get grease in contact. Move it back and forth to coat the ball and the resistance and squeak goes away. The only problem was the clamp bolt threads were wiped out getting the bolt out:

So I walked over to Mike's Merchandise, a neighborhood surplus parts store, and bought a substitute bolt, two washers, and locking nut, $0.28:

Those are WD-40 spray stains on the wheel well. I also squirted down the control arm bolts.

ps. I was inspired by a UK YouTube that correctly pointed out the grease didn't 'leak out'. Remember, gravity wins.

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?
