Lube the splines...

Great thread guys! I've had a read through and think I'm now good to go, minus getting my hands on some grease. Couple of questions that I don't think I noticed - there is a spring in the rear, is there one in the front too? I know with some splines adapters, they need to be aligned when installing. Are there any alignment marks to be wary of? Or can the male portion just slide on in where ever it suits?
 
No spring in the front and no alignment required.
I used string to raise the shaft when remounting the bevel drive. Worked well.
Not seen it mentioned before…watch out for two hollow spacer things that go in two of the four stud holes. Had me confused when they fell out.
 
As an addition to what's been said, that spring, yeah, can be a pain, it wants to drop down (naturally) and then the splines and the bevel box won't align. I got round this by putting a decent dollop of wheel bearing grease in the end of the splined shaft, put the spring in and it stayed aligned. No leakage or issues since I did mine, so I'm calling it good.
