This link on the "other site" seems to confirm the conflict of information re compatibility of different UJs.

Sorry - I meant I did all but the Double Cardan Joint - I would be VERY surprised if the UJ's in your Double Cardan needed doing, the shear nature of the two close UJ's removes vibration and more than halves the vibration/wear etc.... (Plus they are up out the *beep*)

I did strip them and check them at the time - but remember wishing I hadn't!

I think from memory they had a different Toyota Part number, BUT it may just have been that the grease nipple was in a different location or something...

P.s. I agree with Bob - strictly speaking - having a Universal Joint (single one) at either end of a shaft, makes it a Cardan Shaft - but over here we just know the joints as UJ's we refer to the close mated double UJ end as the "Double Cardan"

Thanks for these updates guys - very encouraging that the double cardan joint rarely fails. Obviously I wasn't checking it properly.

I will just do the rearmost UJ and see how that works out first.

Don't forget BEFORE you strip it apart (before you even take it off the vehicle really) make sure you mark the orientation of the yokes.

I center punch each part in a line.... Make a real good mark as you'll probably clean everything up while fitting new part so careful not to clean your marks off....

Tip from me... Genuine prop has all the grease nipples facing the same way.

Dave, how important is it that you do this?

i have just put my 95 back together again after several years in bits, using some parts from breakers, and ive found a deep, rumbling vibration when you put the power down, thinking its a UJ, but would of noticed at assembly if this was the case.

if it is indeed down to putting yolks together which are not suited/aligned, how do you solve it? Confused

cheers

I would say very important - especially if you have a lift!

Have a look at

For a good explanation of why!

As for checking, best option is to find an identical one not messed with and copy the alignment! I can't remember off the top of my head how mine were phased - Bob might have a better answer...???

Bob?

P.s. the bit about "phasing" is demonstrated at the end of the video!

Right so the double Cardan 'Should' eliminate the need to phase the shaft (rear shaft - the front is pretty straight anyhow) so the only real reason to line it all back up is to keep it balanced...

When I re-built mine, I did have them balanced by Bristol Propshafts, they have a machine that looks like a very long lathe and can re-weld lost balance weights onto them etc...

DaveWall · Posted: Sat Apr 18, 2015 5:40 Post subject:

Out of interest Bob did you ever check the phasing of your shafts? Will have a look at mine and see if they are the same...

Dave.

I centre-punched my coupling flanges at both ends and also marked the two halves of the slip joint before taking the propshaft off.

That guaranteed that everything went back in the same position as it came off (one has to be careful when replacing the UJ obviously or the flange could end-up in a different orientation Wink

).

I've not noticed any problems since replacing the UJs.

Sorry to highjack the thread a bit but I have just give my LC a full service and in doing so greased the UJ's. I just used my standard tractor grade EP2 grease but have since found out that you are meant to grease them with a special grease.
Do you guys think my standard grease will do any harm?

I don't think it will do any harm. I use Castrol 'LM' grease in mine (and in everything else) and that works fine.

Any grease will be better than none Laughing
