Today I called Chaffins expecting to speak with Dave re a question I had about axel shafts. I was surprised that Glen answered the phone. He explained that Dave had the day off. I asked my question and he offered a lot of advice and sound tips I could use re installation of neorene seals and outer retaining cups. He probably spend about 15 minutes helping me out even though I didn't need to buy anything. Its good to deal with folks like that.
