I was thinking the the side of the seal that has the rubber flush with the metal goes to the outside. Is this right?

The lip of the seal should point towards the oil side. | | | | | Joined: Aug 2010 Posts: 182 Shop Shark | | Shop Shark Joined: Aug 2010 Posts: 182 | Each of these seals has a double lip. Maybe it doesn't matter which way they go. I've always installed oil seals with the flush side out because I figure if you'd put the side that has the gap out it would just collect dirt in that gap. | | | | | Joined: Dec 2012 Posts: 16 'Bolter | | 'Bolter Joined: Dec 2012 Posts: 16 | I recently replaced the oil seals on my 48 3/4 ton, as you describe (part number visible when installed) | | |
