Front drive shaft broken

Modifying the vehicle in ways that increase the CV angle—like adding a lift or adjusting the caster angle—significantly raises the risk of damaging the factory front drive shafts' CV joint. At the moment, the only solution is to replace the drive shaft. Fortunately, several companies are working on fixes, and with any luck, 2025 will bring reliable aftermarket options.

Also as an update I've done about 35k on the replacement drive shaft with no problems.

Ha! I was just about to ask if the "No Lifters" were also the guys telling girls they didn't need implants because they are perfect just as they are...

I have to admit, I'm beginning to wonder if I'm on borrowed time. Which will cost more, labor to go back to stock springs or changing the CV every 6K like its a dirty filter. I already know your answer, what if the CV takes out the T case.

With the money I'm going to have to spend, I could have gotten a deserving "nursing" student / dancer, enlargements in Mexico.. well, at least one, she can get the other for Valentines day.

Before I get a warning, I return you to your family friendly board.
I appreciate the humor I really do!

Messing around with Grenadier’s is sort of like playing with LEGOS. Some folks like to be wild and use all the colors in the box while others want to be very serious and use a just a few colors in an ordered fashion. Both end up with interesting LEGO constructions and neither is better than the other.

The point being, at least we all got to play legos together and have some fun at least until we step on the damn little sharp pieces left behind in the dark.

I can't see much resolution to the problem until this "dealer installed" question is answered - at least not for current owners. You wouldn't think 35mm/<1.5" of lift (excluding installation errors like @Tazzieman mentioned) would jeopardize the running gear on a vehicle the size of the Grenadier but it is Ineos' call.

As for future production there will likely be issues addressed like a little more positive caster on the front knuckles/swivels or other steering related changes. Conversely, I doubt there's any room to lift the rear of the transfer case. The engine - with insulation cover installed - is very tight under the hood and Ineos won't delete that because of the heat retention properties it affords.

Even if Carraro allows a little more leeway in pinion angle, most of the problems on lifted vehicles are at the front output of the transfer box. The double cardan front driveshaft solution (@Bodhi’s Grenadier I think) seems workable at low speeds but, man, that's a lot of rotating weight to throw around at highway speeds with a full-time 4WD. Will the t-case output shaft's bearing hold? Will the front pinion bearings hold?
I don’t think it seems that much heavier than the factory shaft, I should’ve weighed it prior to install. However, though it has an additional “joint” to it versus a traditional single double cardan, it’s all perfectly dynamically balanced, so it’s not “throwing” weight around as it’s all in line.

More built in caster would be great as well as a more optimally positioned pinion. But any kind of lift is going to alter things, so proper adjustable links would still be needed. This stuff has been done for decades on wranglers now, not really much different of a problem.
