I recently bought a '96 300 4 x 4 Honda Fourtrax. I was told it's one of the best models ever made, even by "opposite brand" mechanics. Anyway, since it was a farm vehicle, it was very dirty, so I used a pressure washer to clean it up...very clean. I either shot too much pressure into the front oil seal around the forward drive shaft, or I washed all teh dirt off of it that was keeping the oil in. Is this easy to replace myself or is it something I should let the dealership handle? Do I need to take apart the front gearcase? Any advice would be great. Thanks.
