Front Drive Shaft Update

[Logsplitter]

Check gearbox casting for hairline cracks. Your gearbox has taken a hit on one of the screws that fixes the plastic pan in place.
First photo is your gearbox pan indicated with red mark. My pan impact I’ve indicated with a green mark.

It looks like there is a good chance the circlip is still in the space behind the cv joint, but you would need to split the back off the joint to get it out.

What's everybody's thoughts about fitting a driveshaft retaining/safety loop?

They seem to be widely available often as a "universal" kit.
The position of the transmission cross member wouldn't make a difficult fit.

Just a random picture

Not my images, not sure if the owner is on this forum but another one for the tally. The photo is borrowed from the Ineos Grenadier Owners Club FB page. The owner has experienced a total failure of the drive shaft and CV. Looks like it has had no lubricant for some time and become excessively hot over an extended period.
Hopefully all is sorted under warranty and there is no other collateral damage to their vehicle.

This thread is becoming more and more comical by the day.

Thanks for the feedback @ECrider.

We don't know what is causing the clip to come out of the groove. The driveshaft should more or less be floating between the two drive flanges (TC and diff) with the slip joint compensating for length changes. The clips are fitted to retain the CV hubs in the correct position on the splines. The clips are a retention device not a thrust washer.

Bonus question: Do you still have the clip or did it get lost? If you have it, does it appear stretched or discoloured from overheating?

I hope the damage is limited to the driveshaft and probably one TC cable

No c clip in sight. There may be some of it left within the tc joint but I havent removed that yet.

This owner had a major service less than 2 weeks ago - vehicle done 115 000km so out of warranty.

I’m nowhere near as mechanically savvy as most on this thread, but I had a thought - would treating the driveshaft boots with silicone spray help them remain supple longer? I don’t imagine it would make much difference to pinching, but if heat / deformation are contributing factors, perhaps it would.

 

[Greasemonkey]

When comparing the rubber boots used by Jeep and Ineos, it was noticeable that the Jeep boots were significantly smoother and more flexible. For this reason, I already sprayed the boots on my vehicle with silicone spray some time ago. This does make them a bit more supple. However, since the problem likely lies elsewhere, it doesn't hurt, but it doesn't solve the issue either, and if I understand it correctly, even the more flexible Jeep boots will be destroyed after some time.

I wondered if they posted on here already but it doesn't look like it.

Thanks for the update!!! This is awesome. We are getting closer to a permanent solution!

 

[Tazzieman]

Noticed this on someone's FB post yesterday; haven't seen it mentioned before. A factor, apart from the angle issue?
"Speaking with engineers from Ineos, apparently some of the units were shipped with faulty, thinner boots that would pinch, fatigue, and crack prematurely."

Depressingly so

That’s disgusting if it he vehicle is stock height, it’s a known problem and should be covered by warranty until a fix is made regardless of km

So where is the recall ?

This is total bull shit.

Sounds like a blanket comment from Ineos to put customers at ease while they find a solution. Pretty common for OEMs to do this with new products until they have developed a proper fix.

This seems a lot like Toyotas tap dance around years worth of badly engineered engines, claiming it was debris from machining and not engineering. They accidentally confessed in a NITSA document the other day as they added another 126K engines to the recall list. that the engines do indeed have engineering flaws. Here is a little secret....I replaced my factory one with a Terra Flex unit and that is what failed. It is NOT boots themselves. It is a bad angle and limited range of travel. That Italian FB photo looks like mine does. However, I checked the boot before I hit the road the day before and it was fine. It was pinched towing over undulating roads because there is not enough clearance. Mine failed and melted down like that in a few thousand feet. Another few thousand feet and it would have been wrecking stuff under neath. I am fortunate it held. Here is the thing, Toyotas are dead last in truck reliability, folks are driving off the lot and having them blow up and fail in every kind of miserable way.....AND SALES ARE UP! Ineos does not have a history of reliable vehicles they can use as a cruch to get through a bad time. However not sure Toyota will ever be as reliable again. Ineos HAS TO fix this drive shaft issue. And they have reliable running gear in general, so this issue has to be solved as a recall or it will destroy them as a new car maker.

No recall because that is NOT THE PROBLEM. I mean, the lead engineer even confirmed it with me.
