It sounds like the the bearings in the diff are shot. It pulls, it just makes a lot of noise and getting louder. I found a guy with a lot of parts bikes and sold me the new diff for cheap was looking to make a quick swap and throw in a toggle switch . But I will tear into it if needed

I have a 2000 450 with a busted front diff. I have a good front diff from a 2004 with the trax lock O want to to run a toggle switch to put it in 4wd but not sure what I need to do to make this happen. I was told 2 of the 3 plugs were speed sensors
