Product review (4 stars): Good quality, made my own bearing presser.
Kit was of good quality. Instructions were a bit bland.
I did not buy the installation tool. The upper bearing goes right in with a light tap. For the bottom bearing, i bought a 5/16 24 thread x 3" grade 5 bolt and 1 large washer and a small one to keep the bolt head from going through the larger washer. Put those on the bolt then take the old drive shaft sleeve and put that onto the bolt. Then take the old bearing and put on top of that. Now you can thread the bolt into the drive shaft and press the bearing in. The extra parts to make the press cost me $1.75 total at lowes! That sure beats the $100 for the install tool.
