Ok, so my car was damaged last week and it just got fixed. However, I don't know what some of the parts are and seeing as the rear differential had been going crazy before the car was damaged, I wanted to know if any of the parts replaced were a part of the differential. The parts were:

1. Output shaft
2. Nut 95v-192
3. Wishbone

If any of those are a part of the differential I would greatly appreciate it if you could tell me which ones and what they do if possible.

Thanks for the help!

Output shaft could be part of it... it normally refers to the shaft that takes power from the differential to the wheels.
