Reply With Quoteon all leafer rovers the yokes of both shafts are set up in alignment with each other.
on coilers the front is one spline out of alignment and the rear is in alignment.

SupporterA couple of of us have been working on a series 1 86 getting it ready for the Outback Heritage Drive in a two weeks time.
The old fella (Drifter) has been rebuilding the UJs and driveshafts and he finally managed to get them ready for fitting late in afternoon.
The problem is we are not sure how the alignment between the UJs/yokes at each end of the shaft should go and the handbook does not make it clear. The handbook does indicate there are alignment marks on both parts of the shaft but on the ones we have the marks are only on the short end.
So on the shaft itself, should the yokes at either end align or be set up 90 degrees out of alignment.
Thanks
Garry
and the ole fella.

ol' fella, huh?
Thanks for the response - interesting about the one spline setting - we inadvertently had that on one of the shafts... only at the rear, not the front.
LordRover
SupporterThanks for that - any idea why the front shaft is one spline out of alignment on coilers?Originally Posted by Blknight.aus

yep, its to do with vibration induced by the angle of the front diff in relation to the Tcase ouput
Why its not 45 degrees out of phase I dont know but I do know that solving the problem by re-angling the diff to suit is impractical.

SupporterThanks - I wonder if it would help with the vibration in a 101 front shaft - it is notorious for the '101 rumble' on trailing throttle.

give it a crack, its cheap and only takes about 20 minutes to change it each time.

Garry - I think we need to talk...

In coil sprung Landrovers the pinion and transfer cases are not parallel. This means that in theory there should be a CV joint at the transfer case end at least*. These are expensive, and it seems that Landrover found that for their utility models (90/110/Defender) the vibration can be reduced to an acceptable level by having a one spline change from yokes parallel. How this works is not clear to me, and I would welcome any explanation as to why it is effective!
* Cross and bearing type universal joints are not constant velocity, but if a shaft has two joints with the yokes parallel and each joint deflected through the same angle, the differences in angular velocity cancel out. This "same angle" criterion is satisfied when the input and output shafts are parallel. This is met (at least approximately) in the leaf sprung Landrovers, but cannot be met in the coil spring Landrovers, as the front diff it tilted up to clear the track rod.

The change of angle by offsetting 1 spline approximately causes the sine waves that represents the relative velocity of the 2 cross pieces to either cancel out or match up exactly. Theres a book at altc to do with drivelines that outlines it all with pictures and overlaid graphs.
What I cant remember or work out is which way the spline is ment to be offset or how to work that out....
