Installed these into my Jeep TJ front Dana 30 and they greased up nicely for a good seal. They slid right into place after putting a little gear oil on them to make it easier and then put a grease gun to them to get that added grease sealant in place. They've so far kept out the dirt but haven't tried them in water as of yet.
I bought this outer axle seal while rebuilding my front axle for the sake of keeping salt and grime out of my axle shafts. My XJ rarely sees mud, if ever, but it is a daily driver and has gone on many thousand mile road trips. These outer axle seal has managed to keep my axle shafts dry as a bone so far for 5000 miles and counting.
Worked great for my Dana 30. Easy to install and keeps dirt out.
Easy to install, does not require any special tools
I like the color, great quality and a perfect fit. Exactly what I wanted and have worked well for my new chromeoly shafts.
