Front Drive Shaft Update

[Dokatd]

I doubt that is ever going to happen. And changing the front axle only improves the angle at the front axle, not the output at the transfer case which, I believe, is the main culprit of the failures. Best would be to redesign the transfer case and put the output shaft lower.

I know this might not make sense, but if you change/fix the front axles angle then you automatically fix the transfer cases angle. They are tied to one another.

I have been following this closely. I have to ask, am I being an irrational if I am having significant concerns about the vehicle and am seriously considering selling it? I have the small Eibach lift and 35" tires so I understand that I am increasing my chances for failure. I love the vehicle, but I just cannot have a vehicle that will leave me stranded. I just drove to a neighboring state to go hunting (which is something I regularly do) and was having second thoughts about driving my Grenadier. I have just over 27k on the vehicle and have not had any real issues. The lift was installed within the first couple of thousand miles. It is my daily driver and I use it for mild off-roading and as my hunting rig. I really want to keep it, but just can't get this issue out of my head. I am not sure what I would replace it with so that is an issue as well. The only vehicle I am really coming up with is a used G-wagon for a relatively similar price point and overall similarity. I would rather have the Grenadier, but this drive shaft issue is eating away at me. I can get over the lack of a remote start (would be really nice to have in my climate), the HVAC issues, and the other quirks. Some of them have actually become endearing to me. Is there hope of a resolution to this matter? Thank you in advance for your insights and hopefully talking me off this cliff!

27k miles without failure is great!!! It's possible you have very little caster on the axle which is very forgiving to the drive shaft angles. It would cause the steering to be fairly goofy, but it saves the driver shaft nonetheless.

Or you just have a unicorn, who knows.

If you don't log in as a user there is a uniquely large amount of ads plastered all over the page, a cunning ploy to make you register and login.

Funny enough that usually drives away users from registering on most sites that do it; there's no indication that it changes with a login, and even registrations paid options highlight placing ads not removing them.

The disability issues were related to the same adverts. They'd pop up at random times, cover the entire page, regularly move their close icons. This is hell when you have motor tics or something else that makes you twitchy like stimming. For those of us who do we often would hover somewhere else to help avoid clicking out of what we're reading. So when ads rapidly pop up and the buttons that interact with it are always in a different place it would always act like we want to follow those links and take us to whatever stupid thing was in the and and away from the forum.


And not falling for the bait continuing the argument I must have been willfully ignorant so another mute goes out to the relevant person and I'll keep muting anyone who tries to debate that because it's not productive.

Back to the shaft stuff

As others have pointed out IA is in a tough spot here in the sheer cost of this kind of repair due to the engineering involved. I think the reason I keep being asked for corp to talk to me (though it hasn't happened yet) is that a fire like this is far more significant than a usual failure.
Loss of Motive Power, as it's often called in the US when some defect leads to sudden loss on the road, is already enough for a recall when the sample size gets high enough. But that is an indirect contributor to a crash or injury, i.e. other vehicles may crash into you, stopping in the road if you don't have momentum to exit, uphill rollback, or you may fail to reach a critical destination like a hospital but it's not injuring you directly.

If that same failure could cause a fire though is an issue that could cause direct harm.

When I was in uni I had to study engineering ethics like most of the department in order to graduate and vehicle recalls were actually one of the hardest focuses. If anyone wants to learn more about the statistics, determining factors, and how complicated the whole process can be if recommend reading the Firestone Recall saga in addition to the Pinto.

I think at this point we all should meet at the Grenadier pub and find a solution over a couple of pints

NOW someone is talking.

Unfortunately this is going to be an aftermarket service or someone with an entrepreneurial spirit contracting with the open axle manufacturer to make a corrected geometry housing… I mean… even if IA shits the bed someday, there are 30000 axles out there that need service. Being an original buyer that has to plop 20k down for either sucks, but, for people buying used, that’ll be reflected in the depreciation.

Eventually, there may be an actual market. Like when they finally made corrected control arms for lifted 463’s.

Right now I’m pinning all my hopes on Dokatd… no pressure or anything.

I know this might not make sense, but if you change/fix the front axles angle then you automatically fix the transfer cases angle. They are tied to one another.

Recently, the shop I had doing my front bumper raised the Gren up on the lift to eye level. They had me step back and see that the transfer case is mounted in an upwards angle, likely to prevent angular issues on the rear shaft as well? I'm sure it has been looked at before, but I wonder what would be a more cost effective fix for Ineos, new front axles or finding a way to lower the TC/Tranny.

I know you've spent a lot of time on the matter. What do you think?

T-case => Trans => Engine

As tight as the engine bay is, changing the tilt is a big deal.
