Rear prop shaft phasing

[Dockstrada]

Does anyone have advice as to how to reassemble the rear prop shaft?

When I dismantled it was out of phase by about 2 splines or aprox 45 degrees, Some recommend the yokes be out of phase by one or two splines, while the work shop manual pic below suggest in-phase.

My 1996 Defender workshop manual says the same - front shaft phased (after some discussion on the landrovernet.com website, I set ours at 30 degrees) whilst for the rear:
"The phasing is necessary on the front shaft only to allow for greater variation in angular changes".

So no phasing required to the rear shaft PROVIDED THAT you have a standard set-up. If you've lifted your suspension then you may require it to reduce vibration in the drive train - but I have no idea how much that phasing would need to be - presumably it would vary depending upon the amount of lift.

As Jode says, the rear prop shaft should be in phase, that is, with the yokes on the shaft in the same plane.

When the drive planes are parellel the prop shafts should be IN Phase

All Coil sprung Live Axle Landrovers inc RRC up to but not including Puma have parellel rear drive planes, But the front diff pinion is pointing uphill - not horizontal, front prop out of phase 45 degrees
but ....


The 110 in your Avatar is a Puma so I'm guessing your reffering to that,
the Puma Transfer Case does not sit level does it, the engine/ transmission is sitting uphill, because of the taller engine the front mounts are higher, which is why they flog bearings and front shafts out when you raise the suspension

So with the rear diff pinion flange & the TC output flange NOT being perpendicular I suspect the rear shaft should really be out of phase too, one spline perhaps. Dont they have little arrows on the mating pieces to show where they line up ??

I totally agree with you , when I went to assemble the prop shaft today I remembered that I had scribed a line on the yoke and the tail shaft , and once I realigned the marks its is exactly 2 splines out . Furthermore it is imposable for the yokes to be in-phase as none of the splines line up they are always aprox ½ a spline out, my yokes are aprox 45 degrees out of phase now without measuring them t be more accurate .

there is a master spline to prevent easy assembly if it is out of alignment from intended position. if it slides together easily it is right.
