Hey guys hope you can help me out. I was driving and when I pulled over I heard a clonk noice. Checked it out and found that the right hand, rear hand break, broke off. It was connected to the inner plate, as well as the break hoses broke. One of the inner plate bolt came off. That's why it happened. Anyway do I have to buy the whole diff or anxle? How can I fix this? Hope this make sense to you guys.

 

back plates are replacable, but you have to remove axle shafts to do.
