These items where for a routine repair


This is a well designed kit that fit my needs perfectly.

The only reason I gave it 4 stars versus 5 is that parts were missing from my original order (Bearing Buddies), and I had to call and have them shipped seperately. They took care of the issue, and I appreciated it.
