I'm pretty sure my front diff blew out the other day. The front diff lock cable broke last season and the other day I was driving in 2wd. Heard a a loud grinding noise and a bang in the front. Now the 4x4 doesn't work. I've seen a number of posts about replacing the front diffs, where did you find the parts? I still have to take it apart to see whats broken but I have no clue where to find those parts. Any help would be appreciated.
