Ranting moan incoming!

Why no matter how hard you try is there always one UJ cup that never gets any grease and the turns to dust!

Three nice greasy roller bearing cup and one full of rusty dust! Quality gkn uj replaced with another gkn uj. Thankfully it is a fairly quick job as everything is free as a uj tends to lay me between 12-24months they get swapped out fairly regularly.

Although another moan on finding more problems one of the handbrake prop bolts has chewed the threads of the end of itself so I could not get a new nut on! Three nuts for the time bearing and then looks like I am removing the gearbox flange at the weekend to replace the bolt (have them on the shelf). That is a job I haven’t done for nearly 10 years so I guess I shouldn’t grumble too much.

Although the hole in the exhaust also found is more of a complaint. I wish somewhere would sell original exhaust section in stainless rather than having to buy the full kit!

I think there is an exhaust manufacturer in Tiverton, devon, that makes SS exhaust bits for landys - dont know if they sell as complete systems though..
My rear box came from them (son used to work there a few years ago). Not sure if they sell direct or through a disty.

You got some spare 1s now though, bright side/silver lining and all that

When you grease the cups once fitted,do you prise open the yokes a fraction to allow more grease in when using the grease gun on nipple.
It realises the pressure on the cross’s shaft.

The UJ is a long time issue and worse with coiler landy's. Higher prop speed I recon.
Some years ago a maker [ I forget who ] came up with an answer, each cap had a plastic valve in its end that shut when cap was full forcing grease to go to the other caps until they were full and take no more. Had a couple and they lasted a long time but did cost about a third more. Wanted some more but could not find, guess most still bought the cheap ones.
Re Hicap's post above regards spreading yolk. Spicer 10 series joints [ not to be confused with the generic "hardy spicer" name] have grooves across the journal end to help get the grease in. [ do not know if available for Land Rover]
Next time I fit a UJ going to use thin disc to cut couple of grooves on each end and see if they last longer. This may take a while as my yearly milage is low these days but I will know as I have recorded all fixes on my truck for the last thirty years.
Perhaps you could give it a go dag19, with your milage we would find out a lot sooner if worth it

I have up keeping spare cups a long time ago when I began to be able to afford replacements rather than utilising dodgy get me by fixes from when I was a student.

Both of you are going to need to eleborate on what you mean.

@Hicap phill what do you mean by spread the yoke? How do you go About doing that?

@tottot what do you mean by a disk, where about a are you referring to in the joint?

Rock Basher · Nov 23, 2023

When you put the uj in it gets tight on the end you press too so does not allow grease to get into one side .
When fitted you have to go back a bit by pressing the other way so that the yolk moves freely a couple of mm each way.
Then grease can flow into each bearing when you grease them. Like a little bit of float .it's a dark art but simple enough once you get the touch for fitting them..

Hope that makes sense....

Using a grinder with thin cutting disc [1mm] to make a groove across the end of the journal
have a look on line "Universal joint lubrication path: Spicer 10 series" for the idea.
