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.

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.
