Statistics/Poll Thread: Front driveshaft CV joint failures

[ECrider]

I'm no engineer but always surprised how shallow the splines are when I look at them.

your boot looks similar to my rip

In my case it wasn’t the boot that failed first I understand. The vehicle was in for a service two weeks prior to the failure and nothing was picked up. It was only 300 to 400miles after that when the failure happened. The explanation from the dealer was that the C clip failed.

I only noticed my rip when I was manipulating it. I think when in situ the only way you can be sure boot is ok is with a good ol' feel rather than just visual. Especially if not rotating the shafts.

I'm still not certain what failed first on mine. Also with a working slip joint wonder what forces caused the splined end to exit it's housing when pulling slowly out of a junction, had the circlip just failed..?

Would the heavy corrugations encounted frequently on Australian out back roads excessively shorten CV life or boot life even at standard height?

Well then Ineos has a problem as the car should be build for these types of toads

Front or rear shaft? Airbag in rear would be a tough denial of warranty if it was a front shaft.

Front shaft

Hi from Germany!
For your information, to record in your statistics, my front cardan shaft broke down in November 2025.

Built 3rd of January 2024
Trailmaster
Stock Suspension
Mileage 36,000km / 22,000 miles
20% Offroad
Front driveshaft replaced under warranty.

I'm sorry for my english.

 

[whiterabbit]

Additionally I have to tell you, that the car wasn't able to drive anymore, due to screaming noises and extreme vibration. Finally it was towed by a company. The Ineos Road Assistance didn't fit, which I think is pretty, pretty poor.....
At least they replaced the front drive shaft under warranty.

Just saw that my front driveshaft is on the fritz.

Mileage: 11,700
Lift: 1.5" Kings (for maybe 1,500 miles). Had it on the Eibach 2.5" for maybe 500 before swapping.
Shocks: Kings w/ adjusters
Failure: Boot ripped at the transfer case

I had no symptoms. Just saw it when I crawled under the vehicle after noticing a coolant leak. The suspension should have been installed with care given the shop is well known in my area and handles many Grenadiers. Had only taken it on a handful of offroading trips without any major obstacles. Rarely drive above 70 on the freeway.

No news on next steps, but I did buy a Terraflex joint. Im expecting the dealer to deny warranty.

Yeah, 10k miles seems to be the mark at which the boot fails.

Failure here resulting in fire toasting the undercarraige.

'24 grenadier fieldmaster trim
Failure at approx 7200 miles
Owl Vans lift installed by prior owner; I bought the vehicle from Elliot Bay Ineos dealer at ~3200-3400 miles I'd have to check for the exact number and lift was on it. There is debate if it is the 2.5 or 4". Dealer cut sheet says 4", but it doesn't seem high enough for that. Owl was cagey when my shop tried to validate info and I was getting quotes to remove it. I was unaware of the shaft issues when I bought it. I'm going to reach out again and try to find a way to identify/specifics to measure.
Failed on open highway in Dallas, TX on a day with approx 500-540 miles of driving
almost all miles since i've owned it have been on-road with some minor light off road in groomed areas (like less than half a mile combined). Irony is our return drive on this trip was going to be when we finally took it somewhere fun :/
Ineos hasn't commented on warranty for the shaft but with the fire I suspect it's going to be totaled. Details in the drive shaft update thread. However the dealer said Ineos corporate is involved and may want to inspect it. My original dealer also asked me to waive my Washington privacy rights so Ineos corporate can contact me directly though that hasn't happened yet.
Fire required extinguisher and still needed fire department hoses to finish off the resulting petrol fire as the fuel lines failed. Transmission, engine, TC, most undercarraige wiring in front of the rear axle were all affected.

Really bad luck mate. Not the best news at this time of year. I hope you get some sort of outcome in your favour.

Thanks.
Having it happen on a road trip from Seattle to Dallas for Christmas definitely has not been the fun drive I planned. At least it happened in Dallas and not the middle of nowhere on the drive.
