The pushrod is not a tight fit in the bore of the bearing. Quite a bit of clearance. The bearing is a ball thrust bearing, and the race also has a little side to side movement, as the balls are between to "plates" to take thrust, not radial loads.
I say that if you have one out at 30,000 miles, replace it no matter how good it looks. A LOT of them have failed in the 20-50,000 mile range, you would really kick yourself if you put it back in and it failed in the next 10K miles, now wouldn't you? I know I would. It is not so expensive to try and stretch it's use to the bitter end.
I don't want to achieve immortality through my work...I want to achieve it through not dying.
