its easy mook.

you will notice when you remove the old bearing there is 3 or 4 press marks in the housings on the outside of the bearing. get a die grinder. remove the pressed down pieces on the housing.

Then the bearing will come out without breaking the housing.

Tap the new bearing in. Then get on the housing on the outside of the bearing and get a centre punch and press it over like it was. Just do it in different spots.
