It’s a faff, but if you have concerns maybe best to remove the shafts from the vehicle and inspect, and grease off the vehicle while fully exercising the joint.
Some people do this every time and will tell you its the only way to properly grease the joints. |

The grease inside the UJ has gone solid. It will be difficult to deal with this without removing, dismantling and cleaning (or replacing) the UJ.

im sure everyone has their own method and favourite gun..
I use a lever operated gun with a rigid discharge pipe ..I gave up trying to use the standard type coupler, even whenni found one slim enough to mate... what works for me is the cone shaped discharge nozzle that terminates in a very fine discharge hole.. that is pressed onto the small hole in the nipple which is sealed by the small ball and its never failed to get the grease into the uj joint..the splined sliding joint will have a rubber sealing collar which can be dislodged to push some grease into that part ...I usually do that when the props are dropped off ... |

You might be able to use a small implement to carefully release the small ball bearing in the nipple housing a bit, so the pressure can build up better rather than blowing out, outside of the nipple.
But other than that, it’s a problem like Blackwolf mentioned which is quite a task unfortunately. What grease gun are you using and pressure? $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

As mentioned above take the props off. Then you can articulate the joints whilst greasing and you can check properly for any play in them.

With the prop off you may be able to heat the UJ to soften the old grease, but go easy because of the seals. Hot water is ok, not a naked flame.

Thanks for the suggestions.
I've been using a push-type grease gun and having spoken to a friend they've said that's probably the problem- the pressure needed to grease the Defender nipples is a lot higher than for an old Series and it's just not possible to do it with a push-type (this isn't the one I've got but is basically the same: https://www.diy.com/departments/8oz-push-t...95_BQ.prd) I'm going to first try a lever-style gun- thinking this one?: https://www.toolstation.com/laser-grease-gun/p29224 And then if that doesn't work I'll try dismantling as you all suggest. I've got no time to do anything on the landy for the next couple of weeks, but when I have I'll report back. Cheers all for being helpful as usual  |

Though it may be more than you wish to spend you might want to consider an Allemite 500-E
Lever grease gun, I would imagine it’s slightly higher pressure than the one you had in the link. (Check I’m just assuming here). And also they have very good following, it has a flexi hose too which helps I have this myself. Also a lock n load narrow release coupler. To manipulate better access, I chock the wheels and jack up one wheel just enough to spin it. Then you can get it in easier to the UJ nipple. Do this only on flat ground on a safe area, be especially careful to secure the wheels and with handbrake on, if you jack the rear be even more careful as the vehicle isn’t secured then so chocking all the wheels is the safest way to go. You only have to jack a wheel up just enough to spin it, no more. I use concrete blocks to secure the wheels, but sleepers would work too if heavy enough sizes. The safest way really is on a lift, but that isn’t practical for most of us for obvious reasons. I try and grease them approx every 3 months. Morris K48 grease is ideal. Hope those suggestions help, it’s just what I personally do. If you can do it after it has been driven that helps as the grease is softer and easier to push out and replace with fresh, but isn’t a compete necessity and beware of possible hot exhaust.  $W33T $0U7H3RN $UG4R

I'll add a photo of the gun and end that I use.. Tried to describe it above but a picture is so much better..
I think those ends are sold as been suitable for injecting grease into nipples that may have been damaged or you can't get to couple with an ordinary end  Click image to enlarge |

No it isn't, they're exactly the same! Granted though a push-type grease gun is likely to struggle. A decent lever gun is an excellent and modest investment. There are tools which can help with coagulated grease, essentially an impact greaser you can fill with oil then belt with a hammer, but they're pretty much the last resort of the desperate grease monkey! Let us know how you get on. Last edited by blackwolf on 11th May 2024 8:22pm. Edited 2 times in total |

It’s when water gets in there and corrodes, or grease goes hard is when the problems start, which is why it’s good to do it regularly it’s also important to make sure the nipples are always present.
Some of mine had disappeared a few years ago, why I don’t know the ones that I put in have been fine. But one thing for sure if one is missing, replace it asap. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

To round off the thread...
I was using a tool that wasn't up for the job. With the push-type grease gun and a non-locking nozzle it was impossible to build up enough pressure to force the grease in. However, using a heavier-duty pistol grip one one (this: https://www.amazon.co.uk/CarBole-Pistol-Gr...&th=1) it was a piece of cake. Thanks all for the advice. |

Thanks for sharing your experiences.
Just had a similar problem myself - could not get grease into the front UJ on the rear prop shaft. Removed the shaft and soaked the offending UJ in hot water for half an hour. This softened the old grease and enabled me to get new grease in there. Must say my wife was not impressed to find a prop shaft in the kitchen sink; perhaps I will use a bucket next time. |

You could have left it in situ and used her hairdryer to warm up the greese
