I have a 2003 Envoy XL with a 6 cylinder engine. My front main seal is leaking.
I looked on Autozone and on Amazon, and there are apparently two front main seals for that engine? Huh?

National Crankshaft Seal 710551
47 MM diameter
National Crankshaft Seal 710605

How can there be two? What's going on here?
Amazon has two! ( a lot cheaper than autozone.)
