Front Drive Shaft Update

[Commodore]

Breather valves might be causing the pinion seal leaks but they have nothing to do with the driveshaft.

The new part number supposedly for better rubber on the boots if I recall. But, that wont fix it as we know,

I wonder if the "breather valve" is just for the weeping/leaking seals? Categorized under Way-out: Is there anyway that a clogged tube could cause a diff to run slower/bind putting a constant stress on the front shaft? Seems like it would have to be really dragging.

Yes - I was unclear in my post, the checking of breather valves is in regard to the leaking seals.

I will ask them out about checking the breather valves since its there for ever. I feel like the Grenadier should come with raised breathers. Cheap upgrade.

Still, a step in the right direction.

Mine recently went in for leaking front and rear diff output seals. Dealer advised the front U joint was seizing. Replaced seals and front drive shaft. Ineos is advising dealers to check breather valves as well, though I'm skeptical this is causing actual issues.

Yeah speaking with my maintenance manager yesterday the Ineos protocol now is to remove (or change) the O-ring from the breather to ensure pressure equalization.
Probably just worth it to add an extended breather kit.

That's an interesting development. I think this is the breather we have, or the same design.
The o-ring would need to be the sealing pad shown as item 3. That's a bit of messing around to remove but it would convert the breather from a 0.25bar pressurising valve to a vent.

And let water right in!.

Yes it's an interesting call to dumb it down - if that's even correct.

There was a suggested practice posted on here to push down on the breather cap occasionally to ensure it is free. Looking at this particular breather cross-section that won't do anything because there is no connection between the cap and the valve. In any case the valve piston would need to be lifted not pushed down.
I do give those caps a spin occasionally to make sure they're not plugged up with mud.

I am yet to fit the EB kit that's been sitting in my shed for a few months. I am still 50:50 to use some sintered mesh filters at the top, or relocate these factory breathers up into the engine bay. In other words: is the 0.25bar case pressure worth retaining in the axle housings

Why don't manufacturers just extend the breathers to up high in the back of the engine compartment?!? Does it really cost that much more to just do it right?

I suspect it's all the little things. Where do you stop. You extend the breathers then what's next.

Granted extended breathers is a bit of a prerequisite for a truck like this though. Land Rover and Mercedes ran them from the factory.

Ineos has not been accused of making amazing decisions though so....

I just saw a video where JRace Industries from Australia said it is working on a fix. Their front drive shaft replacement is undergoing testing for longevity, with no announced release date. The video was filmed at the Sydney 4X4 and Adventure Show in Sydney earlier this year.

Nothing about this on their website.

I visited JRace in October and posted about their development work here and here.

Thanks I missed all that. I am in then out on this thread, missing stuff.
