Bump... Results of the operation.. I have to confess that the picture posted above is NOT really a 2007 situation. The 2007 OBW does NOT have a stub shaft, it has a male axle that fits into the differential.. inside the seal, but many thanks to all who responded and helped me along. A lot of board reading ensued after this post and many hints came through on replacing this seal. Some on target, some not so much... I found the right part numbers and information on the installation tool, which was ordered.... Today was the day to fetch the parts from the dealer. The results of this operation was to find the counter-bot at the dealer entirely too willing to instill fear in me before attempting this. He insisted that that differential cover plate HAS to come off, even though I showed him the diagrams from the FSM regarding the install from the outside of the cover and the seal install tool. He said that I'll find out that the cover has to be removed to install the seal and then the new o-ring, never mentioning the ramifications of removing the cover plate. You could tell this guy had to be working under some intimidation about being in any way, helpful to a customer. So just to make him happy, I bought 2 seals and a O-ring and said I'd bring back the unnecessary parts. This guy was as pan faced as you could get, not expressing a bit of concern or consideration.. almost like he was on camera. So the operation went like this... Looking at the FSM diagram, the seal just sits in the opening. My work collection contains a variety of small tools that have been made over the years for odd jobs, so I tried a hooked rod using a small socket as a slide hammer. Put the hook under the inner edge of the seal and it popped right out. One thing that was obvious is the fact there's NO land for the seal shoulder to sit on. It just rides in the cover The seal is inserted with the spring lip inside the diff, so the new one was lubed with a little white grease, inside and out, placed in the opening and coaxed in with a piece of white PVC pipe that was filed to fit the OD of the seal shoulder. The entire time requirement was about 10 minutes... It took a lot longer to replace that bolt in the diff cover with the notched plate that maintains the setting, along with the 2 stays for the transmission lines. I dont know the reason why you would need that "funnel" tool to expand the seal while inserting the axle. The circlip doesn't even come close to the seal, so what's the protection for. The axle shoulder had a little white grease on it and slipped right into the seal, no issues.. The one thing that really floored me was the attitude of the dude at the parts counter. What a piece of work..
