My drive shaft came off the rear spline while pulling the bevel case. But I've taken the rear apart before and it wasn't terrible. Just one more thing to assemble later on. For now, it's just sitting in the shaft casing.
It looked like the bevel case had its own fill and drain port on it. But I don't recall noticing these before.
It also didn't have its own fluid in it, just engine oil.
I plan to tinker on the engine over a period of a couple months. I'm in no rush. I have until April. My wife wasn't happy with the parts all over the garage, so they're neatly tucked onto shelves now.
With few exceptions, I've been able to put every screw back into it's spot after removing the item. This helps me keep track of the screws. Only the subframe bolts and the bevel gear cover screws have had to remain off.
The front spline looked good (unworn) but dry. Should that have moly grease on it?
