My rear diff took on water a few years ago when I went into the lake while ice fishing and I didn't catch it until it was too late. The thing squeals horribly now to the point I don't ride it. How much of a job will this be to tear into?

 

I have never messed with one but am thinking it would be easier/cheaper to find a junk quad and do a swap. JMO

 

By the way welcome to the foums!

 

You sure it's the diff? The rear brakes on these bikes are known for making noise.

Check your rear brake before tearing into the diff.
