There is a bushing in there that wears. It's pretty much the same rebuild kit from the early 60s up till today as they are still being used on a few new vehicles around the world. There is a pump model that has a ball bearing instead of a bushing but it's very rare and somewhat model specific and not really an improvement over the bushing. One of the few things that has kept a bushing over a roller bearing. Gotta go check on My Little buddy. He has been puking and not feeling good. Geri got meow mix instead of purina cat chow. Meow mix is not good for anything but fertilizer. I went out and got a small bag of cat chow until I get to Sams tomorrow to get the big bag. $4 for a little bag and it's $10 for the really big one at sams... I don't see why anyone buys petfood at wallyworld(on a regular basis) Robert Adams On Wed, Mar 9, 2011 at 7:19 PM, Chris Lindh <chris@xxxxxxxxxxxxxxxxx> wrote: > RockAuto has the seals and rebuild kits for low prices.
