You guys never heard of rotating the shafts around? Something I have done before on other cars. The shafts wear on one side. Swapping them makes them feel new. I have a slight thunk in the back, which is why the shafts are coming out anyway. To inspect them.

I guess I will figure things out. There are not much parts. Just sorta hate it when people tell me what to do. I am refreshing things because I want to. Tell me just to swap fluid does not help...
