Front Drive Shaft Update

[Tazzieman]

Ok So I'm replacing the CV joint on my front drive shaft. I have been carefully inspecting the boot which had only just torn and I caught it before any grease had come out. It tore radially exactly along the line of the gradient change in the thickness of the boot palpable when you insert your finger into the boot.
So please excuse me but from observation of my boot it does not look like a pinch and in fact if you take the still good axel end CV joint to its extreme range and shine a light behind you can clearly see a gap at the apex of the fold. There is no possibility of a pinch that I can see. See images. Or am I missing something. ???

Possibly road debris; we have raised this scenario before.

Possibly road debris; we have raised this scenario before.

And because its a forward facing boot its more prone to debris getting in as it turns.

Looks a lot like the boot fail on mine.

The only thing that stops the joint is "pinching". Meaning the max angle you found was due to the joint hitting physical limits due to the boot and the boot flange. If you remove the boot completely you can disassemble the joint by over rotating it. The pinch happens behind where your light is coming through. Your boot failed in a very normal manner and ist how they all fail. Cut a cross section of your boot and you will likely find the thickness of the boot varies at the spot it was split. The boot however should be uniform thickness in the area it split.

This will be a hugh problem for Grenadier owners when the 5 yr warranty runs out. Most of us are not equipped or knowledgeable to do this type of repair. Most of us non-overlanders , do typically drive ~80 mph on pavement much much more than 20-30 mph on trails.

Values of used Grennys will plummet when the warranty ends, unless IA steps up and extends the warranty for certain parts. All this certainly puts a fear in us non-overlanders (ok, posers).

Takes all kinds of users to make a company succeed.
