Review on 🔧 710494 National Axle Shaft Seal: Enhanced SEO-Friendly Product Name by Michael Hellewell

Put this on my 2003 F350 6.0. You need a tool to fix it on the axle, and after installing it on the car, you need to use the tool again to fix it on the hub. Here is this tool: https://www.amazon.com/gp/product/B0015PKC5W/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 This fixed my auto hub lock leak. It's a lot of work, but take your time and do it right. I saved myself a lot of money doing this - it was worth the time/effort. If you've gotten this far into your hub and have NOT replaced the ball joints, that's a good thing too. You can rent tools for this at any O'Reily or other local auto parts store.
