At lunchtime today I set about trying to see what affect articulation has on the propshaft length.
Well.. this is interesting. So the new prop came with a phase alignment of 30° out of phase. I was aware that any misalignment of of the yoke would cause vibration. But the bring diff nose points down, by perhaps 15°, so this misalignment I imagine caters for that and cancels out perhaps. Also, the splined end of the shaft has to go at one end, now I did a little googling and no one could agree on which end. Haynes manual says splines always go to the forward most end, but many say that splines should point to the transfer case. Who knows, I put with splines to the transfer case. I may well flip the front prop as I think that the other way will allow water to leave the splined end. The old propshaft was incorrectly phased for a front propshaft.
My new prop turned up today. Along with a 15mm spacer. I discovered that the prop should be 45° out of phase to remove some slop or slap or whag ever. Alan told me this, I think i need to fix the rear prop now, as i think that’s wrong also. All fitted up it is 24mm opened up. I imagine this is okay. I can’t imagine that it’s going to close up more than that and should now have some added space to open up.
Abigail complained about the noise in The land Rover the other day, so i checked the propshaft UJs and found that not only was the UJ shot but the splines were rather lose also.
