boss:
well not problems as of yet......but i havnt got the cranked arms in yet.
should i try the arms and then see what happens?

Range Rover Blues:
Yes, if you are getting them anyway then try it with a standard prop, at least that way you'll know the Cardan joint is doing something, oh and check the UJ angle at the gearbox once the castor correction is fitted ;)

How technically were you being?

I dug out this old CAD model I made a while ago, to measure the effect of a spacer.

For further explantion of this model refer to
http://www.mud-club.com/forum/index.php/topic,46492.0.html

By adding the equiverlant of a 50mm space to the diff input the differance between the working angles of the UJs (what actally causes the vibrations) was improved, though only by about half a degree at most.
The working of the UJ at the transphere box end was also reduced (means it would last a bit longer), though only by about 0.2 of a degree so not by much.

Conclusion
Adding a spacer at the axle end will if anything improve the front prop angles on a land rover, though not by enough to get all excited about.
