      Comments about National Oil Seal:

      National #450094 does NOT fit the AAM 9.25" front axle of my 2004 Ram 2500. The outer diameter of the seal is too large to fit in the housing plus the design of the seal is inferior to the OEM seal design. The OEM seal appears to be of a higher quality and the design is better. If I'm gonna take 3+ hours to do these seals I'll spend a few bucks more per seal to do it right. Too bad I found out now and gotta have the truck down for an extra day while I source those parts.
