After greaseing the prop shaft sliding splines I wondered if you could fill the area with something like Land rover swivel grease. To stop it getting in the final drive put a felt washer on top of the input shaft bearing. to put the grease in, drill and tap a hole 1/3 way up transmission tube and put a brass plug in it. Any comments before I try it would be appreciated-----Just wondering at the moment  

Hi Gordon,
Some time ago I played with the idea of creating an oil bath for the final spline.

On reflection, the reason the oil didn't stay in place was because I was using an unmatched pair of splines that were somewhat worn, so the seal couldn't cope.

One day I'll re-visit the plan using my good splines and, maybe, an oil and grease mix.

Oh, and BTW, the rear spline doesn't slide. I proved that with a clock gauge and also the witness marks from the oil seal on the drive shaft.

But there is a seal on the input of the pinion bearing, so why would you need a felt washer?

You would be wasting a hell of a lot of grease without any real posibility of any of it getting into the spline where it is needed. Too much grease in there and you have a good chance of it overheating.

Many thanks guys for your input,I should have realised at the time that the arm is no more than a torque tube. However, it still shows if in doubt---ask. We are all lucky on this site to have such a wealth of knowledge available. many thanks  again Gordon.
