Anyone who owns a Kawasaki Prairie , Brute Force or any other machine with the Kawasaki driveline will eventually experience front differential seal leaks, water intrusion & bearing wear..
My front pinion seals are leaking again on my 04 P-700 so I got on EBAY & looked up BossBearing & found this kit since I plan on replacing the pinion bearing this time, I believe bearing wear is causing pinion shaft play causing the seals to leak.

It`s from Tennessee, I just ordered it so when it comes I will provide the name of the company that made/shipped it if they deal direct without ebay for those who dont want to deal with ebay...

The tool from Kawasaki is $180 so I can see why some guys are making this tool out of Plumbing tools & welding in material at the base and welding a socket to the top but if the nut is frozen in the housing you could do m ore damage without the proper tool....Also the plumbing tool can be weak & the time & material invested is not worth it since this tool is only $67.00 shipped to your door ....

 

I received the tool. Arrived quickly from a company called
Turtle Fountains LLC out of Galloway TN.
Apparently they custom manufacture tools along with fountains.

Just bought one of these kits from Bossbearing.com. Great kit since it has EVERYTHING you need in one place and its a good price. Had to call in cause ebay was screwed up for my payment and they are great people to deal with on the phone as well. Ended up buying my swing arm and arm bearings from them at the same time.
Good experience with these guys so far....

Thanks for the post, it helped me out.
