I bought this from Amazon it fits my car and it might well fit a 2005 Chevy. Only it doesn't fit on the rear shaft of my 2WD Chevy. This is a transmission case seal----not an automatic transmission output shaft oil seal. My Chevy is a full factory 2005 1500 2wd auto 4 speed and this seal is much larger. I've swapped out my carrier bearing and gimbals and it doesn't even come close. fit. This is Gm sku #SKU: 24232325Other names: Automatic Transmission Housing Gasket Gasket Not a problem for me as I have a 2005 Z71 commuter and am pretty sure that's what it's used for.
