I read the article on OFFROAD.com about the 35-Spline Dana 60 upgrade and they were talking about the new hubs they used to complete the project. The part #'s they used were: #38787 - Single Hub for 9" Rear or D60FF Rear axle #38786 - Pair of Hubs for 9" Rear or D60FF Rear axle These worked on their installation, but they have a "lock screw" and "blocker ring" since they are designed for a rear axle installation. In speaking with fellow CK5 member "JK5"...I learned that Warn also offers a 35-Spline D60 Hub kit with the follwing part number: # 62672 - A 35-Spline Hub specifically designed for a FRONT D60??? Most of the Warn Hubs on theire website use part numbers that start with the number "3".....this new kit starts with a "6", and I'm not sure what that represents. At this point, I have two different part numbers from two trustworthy sources. I'd just like to know if someone can explain what the differences are between these? I tried downloading manuals from Warn, but their site doesn't even list a D60 in their application guide!!! Basically, their site is way out-of-date and not very useful for answering this question. Any ideas?
