Hello all, some advice needed please
I'm fitting new steering UJs, but when I removed the old ones it seems the upper UJ (NRC7387) had been fitted at the bottom and the lower one (NRC7704) at the top, either that or the whole bar was upside down (must have been like this for the last 15 years since I bought the vehicle!).
So before I refit please can someone confirm the correct position of the various bits?
1. From what I can make out from the diagrams Ive looked at, the long section of the bar should point downwards.
2. The smaller UJ is the lower one, that seems straightforward.
3. The bigger UJ is the upper one, but which way round does it go? Which side do the longer arms connect to - the steering column or the collapsible bar?
Many thanks, Clive
 
see here https://www.lrworkshop.com/diagrams...ering-column-lower/lower-steering-shaft_53703 the UJ direction is confirmed by the thicker UJ end, i.e. part#7

Thanks v8250, I found that diagram before.
I have the middle version so the orientation of the bar is clear, but the UJs appear to be the same in that diagram. The upper and lower UJs I've bought are different however, and the diagram does not make it clear how they go.
I've attached photos of the two ujs to show what I mean. The upper one has one side longer than the other

I am unsure, But aslong as the pinch bolt locates in the slot on the shaft, that to me would inidcate there is enough shaft in the joint. Then it should be ok.
But you may find that as 1 is longer then the shaft assy may end up being to long.

I guess some trial fitting is needed.

But if you are unsure as it is the steering, then you may want to order some more (correct bits) after talking to somebody.

Then go onto lrworkshop, click on the UJ component numbers and x-ref' against what you've already bought. If correct, fit UJ's. If not, buy correct part no's.
 
OK thanks. I bought the right parts, and they are identical to what i took off (just that they had been wrongly fitted with the upper UJ at the bottom and vice versa).
I've been driving it for 15 years with them like this so maybe its not that important in any case!

I'm just not sure whether the long arms of the upper UJ point up or down, but i'll try both ways to see which seems right and go for it.

thanks for your time
cheers
 
Okay, good luck, they can be a fiddle sometimes. I find cleaning out the splines with a small wire brush the best way, clean off with WD40, wipe dry then a small coating of copperslip/grease on both splines works a treat.

I've got a 1996 Defender 90 300Tdi and I've just had a look through my rebuild pictures for you.
