I have a friend who needs to replace the seals in a D60 rear. From what I could tell in the tech section, it looks like the seals can be replaced pretty much like a 12B, pull the C-clip, pull the shafts, R & R seals, reverse order and all done. Is this correct? If not, what else is there that needs to be done? If it's that simple, no problem. I've done a 12 but never witnessed the inside of a FF60. Any help would be greatly appreciated. Thanks.
