Same thing happened to my G500 several months ago. I pumped some grease into it and was silenced - bought me some time. I replaced it this week.
I'm going to take the old one apart to search for the cause of the clicking noise. I wonder how long the original would have lasted with regular greasing?
Question for the more experienced members; should the homeokinetic shaft be greased thru the boots using a needle zirc once they get some age on them? What could it hurt and would it add to the longevity?

I've been using a needle adapter and grease too. It does quiet down the CVs, and might prolong their life indefinitely. However, the boots will eventually degrade to the point where they won't hold in the grease at all.

the clicking you hear are the balls in the cage without sufficient lubrication
I have tried re-greasing and rebuilding - if balls and cage show signs of wear, it is a waste of time

Agreed. By the time you hear clicking the CVs are way past any repair.

Unfortunately this is common with most dealerships...they love to throw parts at issues without proper diagnosis. Land Rover dealerships are even worse.
When I read your post about the dealership replacing mounts I just sighed. My vote is center driveline CV's. I will be an optimist here and assume if you had internal damage to the diffs Or TC you would have seen/heard the problem get worse (much worse) with the hundreds of miles you put on the car after the issue begun. It appears to me in your new video the clicking is subtle and less frequent. I would assume the stiffer new mounts allow less flex of the engine and drivetrain thus making sound less dramatic...which would point to driveline.
Another option would be to find a G-specialist Indy mechanic in your area - may save you money and help solve your issue faster.
Hang in there and let us know how it goes.

Before dismantling it is necessary to make marks

Yes it is. Mark the position of both CV joints relative to the T/C and the Transmission flanges. I would also mark the position of the boot clamps and the CVs to the short shaft as well. |

Alan,
What grease do you recommend for this, and where is the best place to do the stick? 15 yr old CV's and counting. |

Alan, What grease do you recommend for this, and where is the best place to do the stick? 15 yr old CV's and counting. Out of expediency, I put in the high pressure extra-sticky grease that I've been pumping into u-joints. Probably not ideal, but the reality is that the CV lives a pretty easy life (were it not for the boots cracking).

And the brand/type of grease is? Where's the best place to make the stick in the boot?

The last tube I have is in the grease gun. Definitely don't want to open that thing up until empty. It wasn't anything all that special. Ideally, one would use a tube of GKN CV Grease. I didn't happen to have one handy. The needle stick should be as close to the center shaft as possible. Ideally, one would loosen the small clamp and slip the needle between the boot and the shaft.

Thanks Alan. Any good recommendation based on your experience as to how much (how many pumps of the grease gun) grease to inject? |

the main challenge of injecting grease into the boots is the fact that there is no escape for air
one would need 2 small holes in the boot - one to inject, one to have grease/air come out
holes should be as close to the shaft as possible
otherwise the rotational force will eject the new grease through the holes
so, the greasing should be done with the shaft removed and careful opening/closing of the boots |

I have a hunch that any excess pressure will vent out through the injection hole once the needle is removed. |

I've been taking all my MBs to Clear Lake (old Arod) MB. Best service with flat bed pickup/loaner car drop offs etc.
G was in the shop during the Thanksgiving week so I ended up buying a new Grand Cherokee Summit to use as main travel suv for the moment. |

Isn't there a Refurbish kit that is sold with two new CVs that you can then attach to the shaft and then...alles gut? Rather than replacing the entire shaft? |

I've got the kit. The problem is that, so far, I have been unable to loosen the bolts. The three I have removed (to keep balanced) were cut off. The shafts are also available in different lengths. This would be useful for people swapping in different engines.

Which bolts were cut off??? |
