Has anyone torn into the differential unit on their 3200 series? Just wondering what Im in for this weekend when I yank it out and split the halves apart. Also if anyone has a repair manual and wouldnt mind emailing me the teardown and assembly procedures, it would be greatly appreciated. I wont make it to the dealer to get a manual before I start teardown. Gotta keep this tractor running, it is my only mode of snow removal short of a shovel! LOL!!
