Front drive shaft broken

[Walter]

Bad news. The dealer just called and said this issue isn’t covered under warranty because of the aftermarket lift. Even though they installed the lift kit, they claim I didn’t provide a drop kit to lower the driveshaft or axle—though I’m not entirely sure what they mean.
I explained that Eibach doesn’t offer a drop kit and that this issue has happened in other cases, so mine isn’t the first. They said they’ll contact INEOS and get back to me.

I think it's safe to assume that if the car is lifted and the drive shaft breaks that there is little warranty.

The question I keep asking myself, given the obvious link between lifts and front drive shaft failures, is why bother lifting the vehicle when you can use 33 or 34 inch tires (which is the size range almost everyone is running) with zero lift and no rubbing. Especially when installing only springs and shocks does absolutely nothing to increase tire clearance. The suspension can still compress to the OEM bump stops so tire clearance has not changed in any way. All you do is reduce available suspension droop and increase angles on the prop shafts leading to these front shaft failures.

I guess well you do get a little more approach / departure / break over angles.

For me, not really needed so I simply moved up to 33” tires and called it a day with stock ride height.

I too am on the OEM suspension. Running the factory steel wheels with Mickey Thompson Baja Boss tires in 255/85R17 which have a spec of 34.6"x9.8". No rubbing of any kind under any conditions and these are as tall as most tires labeled as 35s. With these tires the angles and ground clearance are completely sufficient for anything short of technical rock crawling. The Grenadier is not designed for the rocks anyway, that is what my Jeep is for.

Because years of marketing, aggressive aftermarket industry, social media and trying to keep up with peers demands big vehicle lifts and huge tires… sort of an automotive equivalent of body dysmorphia syndrome? “Not that there is anything wrong with that.” According to some TV show in the 90’s.

Truth is, everyone of us can get by in life without a Grenadier or similar 4x4 vehicle… for most it is a lifestyle choice/statement and a source of entertainment and fun. Everyone can modify their vehicle how they see fit and for whatever purpose they intend to use it for so long as they are comfortable with the Pros & Cons, of which, they’ll be many.

That said, it’s always amazing to see what a sensibly modified near-stock vehicle of any brand is capable of in the right hands. Reliability is what I want for my personal build but others choose different paths and that’s okay.

At the Game Fair UK this year they had a Safari Ineos Grenadier converted by Ineos Kavongo with 34-1;2” tyres . I wonder what suspension lift they had and what drive line and suspension upgrades they did for that vehicle. Bearing

in mind this is an Ineos owned company.

I run 33.5" tires and I'm really happy with that choice. Now when I was in Moab did I wish I had an extra inch? Yeah for sure. But waiting until we have more data on longevity and issues with the lift kits.

Reliability and low weight are my primary goals for the Grenadier. Unlike with previous vehicle builds when I let the weight get out of hand and needed all kinds of modifications to run big tires and add strength to the drive line.

I am even considering dropping down in tire size. The Baja Boss tires are great in 255/85 (spec of 34.6") but the Grenadier does feel slightly over geared and no gear sets are yet available for the Carraro axles. The ideal tire size without a regear is likely 33" to 33.5".

What specific tire are you running? I am considering the Toyo AT III in 34x10.5R17 (spec of 33.5" x 10.6") to replace my Baja Boss tires.

Those tires will fit with a factory suspension. You do need a wheel with a different offset which is what they have done.

Given the 12.4" width of these tires a lift of some kind would likely be required to clear them or maybe just a specific wheel offset. Not to mention the additional spring rate needed to carry that many passengers.

Edit.............Commodore beat me to the punch on wheel offset. But no doubt a custom spring rate in the rear to handle the payload. Looks like 8 seats in total which is easily 1300 pounds of body weight.

I'm not sure you are going to feel that much difference between a 34x10.50r17 and a 255/85r17.

Lifts don't add clearance unless you also change the compression stop.

Ever see the guy who is really into outdoor gear and buys all the super expensive hardcore winter clothing and because he’s so into it you see him wearing it all at once even though it’s still August? As if he’s going to turn a street corner at any moment and suddenly be confronted with the side slopes of Mt. Everest and be in a fight for his survival?

I see plenty of those kind of 4x4 rigs in my area and from time to time it gives me the giggles… but hey, should a giant mountain suddenly appear they’ll make the rest of us look like idiots as they zip right over it and survive!! It’s all good fun and I’m happy for the variety as sometimes you see things you may like for your own projects.

No they do not, just as I mentioned in a post earlier in this thread. But for what is an Ineos owned company they could easily have engineered extended bump stops if needed for this specific application. It is a fully customized vehicle for games drives so it could have all kinds of mods that will never be offered for sale.

The height difference is a full 1" per the spec of each tire. That could definitely be felt from a gear perspective especially considering the 9 pound weight difference between the Toyo and the Mickey T. But the smart call is probably to drop to a spec'd size of 33" which is still 1.5" more than the OEM tire.

wrangler duratrac lt in 275/70R18/. 33.16 inches on steelies.

however if i would do it again i would seriously consider the KO3's or the geolandar M/T G003.
