You guys are awesome, thanks for your help. The right rear wheel seems to spin a bit easier than the rear left. Also, there is a lot of play or wobble in the wheel. It seems very loose.
What is involved with changing an axle shaft? It looks like the differential has to come apart somehow.
Is it common for an axle shaft to break? I was just turning onto a paved road from gravel, and of course the road was terrible.
