Review on 🔧 GM Genuine Parts 291-319 Rear Axle Shaft Seal: Superior Performance and Durability by Aries Boyce

Same as my 2505 GMC Sierra 2500HD. If you are a masochist, buy a cheaper non-genuine oil seal. As painful as it is to replace this seal, I think it's worth a few extra bucks for the OEM. Not to mention that if your Cheezo aftermarket seal fails again, you'll also have to replace your oil-contaminated parking brake pads and possibly disc brake pads again.
