I tried it today--it does work good for muffler bearing removal--hardest part was finding the bearings!

You do not replace muffler bearings you take them out ,turn them around and install them. You can do this 5 or 6 times before replacing the muffler. I used to go to meineke and pull the bearings out of their trash and sell and install them backwards and the muffler was good for another 20 thousand.  bob w.

Looks like something I used back in 1961 in Honduras during Interrogation training.
