The rear shock removal technique is flawed due to the amount of leverage that can be applied, bearings can be forced to rotate in the housing.
I’ve checked 750 = 1000 frames. a lot of the time the frames feel OK and don’t sound too bad, once you strip them down and check them individually you see how bad they are.
What costs less new bearings and to fit them yourselves or a new frame ❓ Checking your bearings once a year or once3 every two years is the only way to insure that the money you have invested in your frame isn’t lost.
It’s also the only way to ensure you get all the performance benefits out of your frame that you should.

Anyone wanting to check and renew your bearings, it’s a fairly easy straight forward job, if you have someone of years of experience teaching people how to do it.
You could service your frames with what ever is lying about and do a better job than most bike shops
