Americas Front Driveshaft CV redesign

[Commodore]

Ineos crew, there is an issue with the front driveshaft CV at the transfer case side. The acute driveline angle generates heat causing the rubber on the CV to rip and spill grease. This leads to failure of the CV joint and ultimately immediate loss of forward propulsion. The failures have been well documented. Do you have plans to redesign this part or should owners start looking for their own permanent solutions?

This is a serious safety concern that needs to be resolved.

They added this later.
I had the springs on order as soon as they were available for sale and my truck had not yet been delivered.
There was no warning at that time.
I had my lift installed myself, but many trucks were sold modified, or offered to be dealer modified at purchase.

In the US when a dealer offers modifications or has a modified new vehicle for sale, there is an implied warranty.
Ineos may not have liability due to the lift, but we all know that no dealer sold it with any driveshaft disclaimer.

For the US, this is barely considered lifted. The minimum that typical pickup drivers do is a leveling kit.
It sucks that this small spring change equates to Ineos dismissing the problem.

I still love this thing.

Then the dealer should provide the warranty

Experts: What IS the solution?

If any...

Let’s see what Ronny Dahl decides?

It's interesting that reading up on CV joints as invented by Mr Rzeppa 100 years ago, that heat management has always been an issue.
I saw that Terraflex has a special grease formulation, presumably to combat this.

ultimately immediate loss of forward propulsion.

Does it end up in dry dock, or is it a float repair?

We should use the abbreviation for any problems with the Grenadier WRDD

Going of a video posted in last 24hrs on the joke thread, I'm guessing he'll be using Vegimite to pack the joint rather than grease

Is the drivetrain setup exactly the same on the QM (just a longer rear drive shaft to account for the extra foot of wheelbase?)

 

[C-Mack]

Most certainly IA is paying particular attention to such a prominent YouTuber putting the QM through its paces so if something did happen involving the front driveshaft how thrilled would IA be to see that? The worst would be if IA offered some sort of special support or assistance just because of the social media exposure at play.

Would the rest of us mere mortals be able to expect the same kind of treatment should it occur? IA is going to be biting their nails and walking a fine line on this issue so it’ll be interesting to see what if anything happens should a failure occur and how it gets resolved.

I’ve asked my dealer that same question on 3 occasions - they have assured me it is, but I’m not 100% convinced.

Whats different?

 

[Commodore]

I keep reading here that stock, unmodified ones are failing but I’ve not yet read one that has, at least that I remember. Granted, I’ve been reading here consistently only about two months…Will he who experienced his unmodified CV joint fail please stand up and share?

I'm one of those who had a CV boot rip on a Grenadier with an unmodified suspension.

I just feel like the steering feels different, and it’s hard for me to accept this is purely because of the longer wheel base. It feels like there HAS to be something different up front, but the dealer assured me that’s not the case.

12" difference in wheelbase is significant. Tahoe/Yukon/Escalade to Suburban/YukonXL/EscaladeESV is a 13.2" difference. Having driven many many examples of both wheelbases over the years, they handle completely different from one another.

There have been a small number of failures reported on stock vehicles on these pages, I would suggest it’s less than ten, possibly even less than five. But it has happened.

Yep. This document is included with Eibach Pro Lift kits and the same info is on their website.

This info was not included when I purchased my lift. I spoke to them multiple times about reported failures before I decided to take the risk. I talked to OWL before install to make sure they didn't let the drive shaft droop during installation. So far I have been lucky. Installed at 9000 miles and I am just shy of 24,000 now.

@terdrocket said the same thing a few posts back. I have no doubt Eibach reacted quickly when they learned of the CV issue.
My point was that Eibach (now) include a caution about the driveshaft so it's on dealers and installers including DIY to understand and accept that a lift is not going to make the CV situation any better. You're testing the edges of the warranty if there is a failure that can be attributed to the lift.
Get informed.
Assess the risk.
Proceed if you are comfortable.

There seems to be some confusion about Eibach Pro Lift kits. Despite being the same brand they're 100% an aftermarket modification. They're not listed in the Ineos options or accessories catalogue and have no official recognition by Ineos.
My point (2) above is for Ineos to clarify their warranty position re standard and lifted vehicles. We might not like the answer but we need to know their position. Too many owners have had repairs delayed while dealers and Ineos debate warranty matters.
