front prop
Hissy:
I have a 300Tdi discovery (1997). Fitted with a 2" Lift Kit.
Because the front prop, transfer box output flange etc, are more out of line than they should be. I've broken two uj's (transfer box end).
To try and cure the problem i've fitted a Td5 front prop with the Cardon Joint (approx £170 from Britpart). The transfer box output flange also has to be changed (flange,oil seal, nut, felt washer,large cir-clip, nuts & bolts) got the whole lot from a local gearbox rebuilder for £20.
A big reduction in vibration :(bigsmile):
Now i just gotta sort the back end out :(bigshock):
Damonski:
All these extra costs for props and things are what really put me off lifting mine. Although I really want to see it 2" higher :(
What would be nice to see is a total shopping list for really doing the job properly.
Shocks, Springs, Brake Pipes, arms, front/rear props etc. Can someone put that together in a new post that can then be made sticky on the forum?
Unfortunately i dont like the idea of trying the 2" lift and the "you might be ok without changing the prop" lol

I havn't done the calculations but if anyone is proposing to make a 2" lift then the front prop will have to be upgraded to a double hookes in every case. The installation angle is just too high for a single cardan (above 3-5 degrees which is optimum). The existing single cardan may work initially but its life will be reduced dramatically and failure is inevitable.
As a matter of interest. On TD5 diesel auto's we fitted a special sliding joint to reduce vibration at tickover. It is a known internally as a ball spline. I would recommend this upgrade for any Disco owner as it is a far superior sliding joint than the conventional.
Forgot to add. Disco Owner, 02 TD5 Adventurer. Propshaft upgrade (ball spline) :) .

Is this an upgrade as in something you can fit to the existing propshaft or does it require a whole new propshaft? (I think I already know the answer but it's best to ask!! :lol: )
I only ask cos most of us that have the double cardan prop fitted don't want to spend another £150 - £200+ for another new propshaft but it'll be handy for those looking at an initial change. :D
GKN & Land Rover part numbers would be handy if you happen to have them. :wink:

Whole new prop I'm afraid. I'll post LR part numbers when I manage to look them up at work next week.
