You are the bomb.com my man.That’s what you are supposed to do. Open the set screws three revolutions (I mark with a paint pen to ensure I have the extra right of amount of revolutions), then perform all suspension work. Once all work is done, I jounce the suspension by a very short drive over some in even terrain, then part the truck on flat ground. Wait 15 minutes (as per the Toyota FSM), then tighten the set screws to their factory torque spec of 10 lbf.
If you go too far in unscrewing the set screws, you won’t get much air in, what will happen is you will get a bunch of pressurized hydraulic fluid blasting out. I had a customer call me after a Toyota dealership installed BP-51s and he said that the ride felt “off” and the was smoke coming from the driver side. Well… that was the KDSS fluid blasting over the muffler and burning off, then an out of spec KDSS pressure leaving no sway bar feeling. The dealership said they weren’t sure how to fix it, and just paid me to do it.
Best thing to do, is just follow the FSM when doing any work, and you’ll be golden. If you run into anything, just shoot me a message.
Just wire brushed - painted (happened to have the same paint you mentinoed) and about to anti-sieze my 2017 with hex (odd, but thankful it's hex). I'm in TN so after 5 years the screws cracked no issue, but better take 5 minutes more while I'm greasing prop shafts and u-joints and knock it out.
