Quartermaster Failed Driveshaft - Be Aware

[MileHigh]

Inches, angles, blah, blah. Can barely fit the stock one in my garage…. Let alone getting my old, fat ass into the thing. I did just raise my seat from the bottom position, so I FEEL higher…

Why a 4” lift for 35” tires? Two inches is sufficient and will have less impact on the driveline, suspension components and steering.

I test drove their Ineos with the 4 inch lift and 35's before signing off on the build.

I have a lifted '05 LJ Rubicon and a lifted '22 Sprinter 170. (Kings on both)

Here's their data on the CV joint tolerance.

Ineos CV Joint Information

Ineos CV Join information for the Grenadier and Quartermaster in offroad applications with lift kits.

ready.owlvans.com

"The Maximum continuous operating angle for a Rzeppa (receptor- style) CV joint on a driveshaft is typically around 22 to 24 degrees for continuous use. 45 to 50 degrees for temporary articulation, like in suspension travel or steering (but not constant rotation). For durability and to avoid vibration, heat, or premature wear, it’s ideal to keep continuous operating angles under 22 degrees."

"Grenadier 4.0” lift is 13 degrees at the pinion CV joint."

If the lift on the Ineos becomes an issue then I'll take it to Agile. They're selling custom front and rear drive shafts. ( https://agileoffroad.com/product/heavy-duty-front-drive-shaft-for-ineos-grenadier-by-agile-offroad/ )

I'm also assuming that with the Quartermaster being new there will be continued development by aftermarket companies until they get the lift dialed in.

Pinion side isn’t the issue… it’s the t case side and that is a very real problem. Those of us here with experience with our Grenadiers are telling you that a 4” lift is going to eat CV’s. It isn’t what you want to hear but it is a fact. Also a driveshaft with 1350 u joints is already operation past functional angles at stock night and has a highway vibration. At a 4” lift it won’t live long. I get that this isn’t what you want to hear but it’s the truth.

BTW you can fit 35” tires on a stock suspension. Start there and see if you really need a lift for the trails you are going on.

It's not the Rzeppa joint itself that fails. The Rzeppa is well suited for the higher angles. ITS THE BOOT, THE BOOT STYLE AND SURROUNDING COLLAR ARE THE PROBLEM. And that's completely ignoring the absolute horrible geometry 4" of lift would give you on both front and back axles. Hell, the geometry of both are terrible in stock form. It only gets worse with lift. Develop a long arm kit and things start to make sense.
