Since we are talking about JBA UCAs. I installed a set a few months ago. It says to grease the bushing with 1-3 pumps and the ball joint with 3-4 pumps at about every 3k-5k miles. I understand the bushings, but if the ball joint boot is sealed, or semi sealed, it seems it shouldn't need re-greasing as grease doesn't really disappear that fast?

Give the knuckle a couple good whacks down with a hammer and it'll come free easy.

Just a note for anyone replacing the boot, super simple: Remove the swaybar end-link from the steering knuckle, then jack up the LCA a bit before whacking on the flat plane on the steering knuckle with a hammer and the ball joint will come free easy.
I had a conversation with customer support about this. Only the top of the boot is sealed. The bottom is not; the idea being if you over-grease the extra has to escape from somewhere. Also, personal experience: if you do 3-4 pumps every oil change you’re going to experience overfill. I only use 1-2 pumps and that seems to be the sweet spot.
I installed jba UCA's on my 2004 4Runner - finally decided to set correct caster after over 15 years of driving with 4 deg off with no issues.
When I got the UCA's, I noticed that the boots are not tight on the bolts and there is an aluminum bushing between the knuckle and the boot. I called jab and asked about this unconventional "solution", and they assured me that everything was fine and as intended. I assumed that for that kind of money, they would do it right. WRONG!
In less than a year, the ball joints have failed (yes, I lubed living hell out of them every time I did an oil change) because the boot was loose, and water/sand got inside and ruined the joint. It was not an accident - it was a case of lousy design and/or implementation.
Needless to say, their warranty doesn't cover ball joints...
I was told that chevy silverado joints have the same configuration without jba's defect. As much as I hate putting anything chevy on my Toyota, I have no choice.

I understand the JBA ball joints can be replaced with off the shelf ball joints. Can anyone confirm these alternate ball joints for the JBA upper control arms:
Moog #K6292
Raybestos #500-1062
AC Delco #45D0062
Let me know if there are any other part numbers that work or are recommended.
