OK Ive heard that if you put a spacer between the diff and propshaft or the transferbox and propshaft (to lengthen it)it reduces the prop angle slightly when lifting is this true or have i been told a stinking lie?! :-k
-
It will do nothing to the UJ angle but you can shim the propshaft, IIRC Wizard sell spacers too but these are to make the TD5 propshaft fit.
I can't imagine why you'd want to shim the rear prop at all though, as you lift it both the rear arms and the pro swing forwards slightly.
-
YOu've been lied to.... if anything, technically it will actually make the angle the prop works at WORSE due to effectively making the distance between the flanges shorter.........
-
a lie! god damn it!
im wanting to put castor correction arms on the front but was told that i will need a wide angle propshaft/double cardon to account for the changing angles....thought i could get around the expence..

Ah, this is the spacer Wizard makes to fit the TD5 propshaft (the one with a Cardon joint).

ok thanks, maby i got the wrong end of the stick! :oops:
is there a website? and howmuch are the td5 props?

the wide angle/cardon prop is not critical, some trucks need it, some don;t, fit the arms and see if you get horrid vibrations... if you don;t, you've got away with it!

Search E-Blag for TD5 and propshaft, there were a few on earlier.

Good luck!!!!!!!!!!
Not sure if the atuo ones are the same length, but if they are..... :clap:

The Td 5 prop is 50mm shorter than a 200/300 prop. 670mm against 620mm. If you lift a early disco some seem to suffer vibration problems more than others.
The spacer i have is for the 200/300 front prop and for some strange reason they do seem to reduce vibration in most cases, but this seems to go against most logic as the prop would be 10 or 15mm shorterdepending on the spacer fitted.
My disco has a 3 inch suspension lift and was chewing up front prop UJ's every 6 months, i put on a double carden joint from what i was told was a TD5. It was 50mm shorter than the 200 prop so i added in a 50mm spool piece.
this lasted about 8 months and the UJ's fell apart. it turns out the prop was from a early 110.
I then sent it to the propshaft clinic in Bradford for a full rebuild and its been perfect ever since.

Would it being from a 110 make any difference? and was it the 110 or the stage one V8 that had them fitted when new?
-
Talking to the guys at the Prop clinic it was the stage 1 V8
wizard
-
right, so whats the best plan of attack??
-
If you are chewing up UJ's fit a double carden prop
wizard :twisted:
-
Agreed.
-
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?
-
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.

Clearly not enough!!!! :oops:
