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.

I don’t get how those threads got so stripped, normally that does not happen..any idea?
Nothing wrong with those threads - thar is a mechanical interefeence locking thread design and built that way. Note the base diameter gets LARGER with more nut engangement - thread wear would make it smaller.

NOTE: It is CRITICAL to use only a free-spinning threaded nut and NOT a mechanical locking nut on that type of stud. If you use a locking thread (mechanical deformation of the nut) stud with a locking nut, as they will never come apart.
