Steering and Poor Stability

[255/85]

Each of the Grenadier's driveshafts has two CV joints in it. Jeep has been using this design for a long time now.

But not in any Jeep I've owned. I see the value but I wonder (along with others here) why the double cardan at the swivels?

Yea, that was one of those design choices I was surprised to see, but didn't figure it made any real difference. Perhaps that's the reason they set the steering stops so far out.

Not sure - you mean CV joint in the axleshafts? I don't think I ever saw double-cardan joint in the swivels.
CVs at both ends of the driveshafts are awesome. Maybe they need a bit more maintenance or care, but they [should] solve all driveline vibration issues.
About the Jeeps - JK-JL Wranglers have them. I've seen several torn apart on Rubicon in two days - but likely due to drivers being very throttle-happy and using giant tires without diff gearing change.

My thinking as well.

Yes, in the front axleshafts. I saw them in the demo vehicles but I've never checked again to see if there was a change for production models.

Honestly, I don't know why Tom Woods still offers double-cardan driveshafts. I'd still buy one if I didn't have a CV option - still may buy one for the LWB Classic to replace the garbage single-U-jointed rear driveshaft from BPUtah, but just for the lack of a proper CV option.

Torn CV boot problems? One shouldn't be using driveshafts as rock sliders.

I've had Woods do a few driveshafts in years past before he became a big name. Still have a 3.5" heavy wall long spline between a 205 and a 14 bolt. Definitely quality equipment. Back then he'd pick up the phone himself.

I'm looking forward to having the CVs in the Grenadier.

I have woods driveshafts on my 1967 Bronco and they have been great.

I haven’t got into this thread to any detail as yet. I need to study the setup further but, in the meantime. Have any of these components as fitted failed as yet?

A front driveline CV failed on a member's vehicle in Tasmania earlier this year (February)... https://www.theineosforum.com/threads/front-drive-shaft-broken.12414695/
