I rebuilt my rear differential on my magnum the other day. When cleaning up the workbench I found the thrust button on the floor. I did not realize the thrust button (part number 3233582) fell out and I reassembled the differential without it.

Doesn’t look like it does much on the rear differential, but I am no expert. What does it do?

The bike drives fine, but is this something I need to reinstall anytime soon?

Thanks
