The seals I waited 10 days for were not 2 piece seals, and did not come with an installation tool. I specifically ordered these to get what everyone in the comments described as the “better” 2 piece seals. These were the standard 1 piece seal that has rubber lip that rides on the spindle of the axle, not like the 2 piece rubber against rubber type I took off. I used these as they were stamped National brand and I had waited so long, I needed to get the truck back together! They did fit, and are hopefully good quality. Low review due to not what I thought I was ordering.
