I have a 2004 $WD 1428V and the Front Left wheel is leaking fluid at the swivel point where the part that goes down inserts into the horizontal shaft. The manual shows a seal for the "Final Case" so it appears you have to drop the whole assembly down. They are very sketchy on the "how" part. They say "remove the final case from the axel end" then "remove the cap and snap ring" then "remove the wheel gear", and then "remove the snap ring and drive out the wheel shaft with a plastic hammer". Then, at this stage, the wheel shaft oil seal can be checked. Seems straight forward, and I had this done at local Massey shop, but they went rogue and don't do them anymore, so, anyone have suggestions, tips or tricks? Done auto stuff in the past, just prepping for this adventure.
