Questions about the final drive

good idea to have a service manual to make sure the parts are in correct order. That is unusual for a static o-ring to go bad. It might let water or road grime in. But the straight mesh splines look good, just a little rusty. Need a coat of moly paste. Moly 60 is equivalent of moly 77. There is the long spacer, thin washer, and thrust washer in the hub.
The play in the straight splines are just from acceleration and braking. I have worn these about 1/4 into the teeth before I decided to just get a whole new final drive for $905 from partzilla. That beat the new spline hub and labor to take apart and might need other parts and shims to put back together. Plus too much down time for me means wasting too much gas driving truck. That was on the silver NT, must have been around 160K miles before splines were worn too much

While you have the wheel off also check your rubbers. The rubber pucks and aluminum drive inserts for wear. Here are a view pictures. These pictures are of my old NT with 32k miles on it. just before I sold it. If the aluminum is worn as in the pictures, you can turn them around and reinstall in the rubber pucks. Make sure you lube the spider fingers with silicon before you reinstall it.

Hmmm... :unsure:

This is another possibility.
 
my universal went out at 188,000 miles on silver NT as a reference.
 
Circling back on the M-77...there is no consensus. Several posts raise good questions/share negative experiences with M-77.

There have been several discussions regarding the replacement of the discontinued Moly 60 paste. As I need some spline lubricant I wanted to know what Honda had to say on this issue. I went to my local Honda motorcycle dealer and asked for Moly 60 paste Honda P/N 08734-0001 knowing that it had...

I've used the M-77 for several tire changes now, no evidence of spline wear. It seems to do what it's supposed to.
