Need some diff help!!

[jarek m]

At the end of the shaft there is a spring that prevents the shaft from sliding out, you need to apply outward pressure on the shaft to get the spring inside the diff to align and then give it a hit with a 2.5er. Some springs don't come out in one piece there for hawing a new set handy is nice, my came right out, looks like yours are a little more stubborn that's all

This is a different application but the end of the spline looks same #1.
