Is this a thrust button and can it be removed?

Don’t understand why anyone would put “green” bearings in their car.
Overall unreliable POS.
The factory bearings are WAY better.

A buddy had fairly new ones and one let go on the hiway while we were going to a car show 90 miles away.
Blew gear oil all over the entire back end of his car and that side brakes were soaked.
Then it cost him $300 to get his car hauled back home.

I tried to tell him when he was putting the car together, but all the green bearings hype got too him already.

If you have floating caliper type brakes you can use factory bearings and end play adjuster.
