The first time I put mine in using some all thread, washers, a socket and 2 nuts (will posts pics)
Then the other night I used an 11/16 deep well socket and a pair of pliers for a hammer lol.

I pack mine before installation and grease both the bearing and inner of the arm.

When you go to install them MAKE SURE YOU ONLY APPLY FORCE TO THE SMOOTH SIDE OF THE BEARING. ITS THE SIDE WITH THE NUMBERS ON IT. THE OTHER SIDE IS BUBBLED OUT AND WILL COLLAPSE.
