I think by the time you buy the special tools, decide their use, attempt this for the first time (then worry if it's right).
I would consider letting a "Big Truck" (dump trucks and such) Specializing in alignments (not tire sales/or unrelated repairs) diagnose and replace the ball joints.
They would have the tools, be quicker, and know when it is right.
Besides, you are going to need an alignment to finish off the task.
This may help too, prepare for the climate, this is my hot climate solution, it works much of the time.
The more mature, been there awhile guy, is your target.
If its hot out, a cooler with assorted soft drinks, aids in the "good re pore, bonding process".
Sorta casually grab a soda, take a few, "teasing sips".
Apologize!
Then happily force your well stocked and assorted cooler onto them.
You will be their high-light of the day. You will be remembered the next time.I do this at salvage yards, and other places too. Its sorta like a "discount card" at times.
