Front drive shaft broken

[Dokatd]

Well, it's official, Tom Woods has backed away from the Grenadier front shaft problem. They respectfully declined to continue any development via email today.

Tom Woods works directly with the same shop that Bodhis has been working with and had been discussing the project with them.

Seems Ineos really did a good job at mucking up the driveline on our trucks.

I still have another reputable shop working on a solution, but I'm really crossing my fingers that it's just crappy joints from the factory and the Tera joints will get the job done.

Wait until we get confirmation if Ineos changed drive shaft angles

 

[Dokatd]

Well, when it rains it pours. The other shop just came back and said they do not believe a DC will survive with the current angles. They said the only viable option is a Rzeppa joint like we have. But of course the boot will remain the limit.

So........that's that I guess. At least for now.

The only way this would be possible is with a different front axle. And there is no way they will be going back retroactively replacing front axle housings for this. Unless there is a law suit, which means it would have to be problematic on stock vehicles not lifted ones only.

Think of it as an opportunity for some entrepreneurial spirit to start a cut an turn service. all that's needed is a couple cores to start.

I kinda think volume is a factor. I mean, they sold me a driveshaft for my fj40 and they have no idea how lifted or how bad the angle is, did I shim the axle, did i cut an turn the balls?. Nothin. Just a shorty long travel drive shaft with a dc at the case, and U at the pumpkin to my specified length, no other questions asked.

bad news on my end, just completed my 5th oil change(30k miles) and inspected the replacement Teraflex joint. Boot is torn, Zero offroading. I see no other choice than to have the Eibach lift removed. Luckily I have a new OEM shaft from when the original went out. I got ~ 10k miles out of the Teraflex. super bummed.

Did someone say "50mm body pucks?"

I had suggested the same thing several months ago. Someone commented that they pinon bearing lubrication might rely on the existing flat pinon angle. I find it sorta hard to believe that is the case but maybe it is.

The process of cutting and turning wouldn't be that difficult if you built a jig for it and had an established process.

Or, leave the ride height stock as their engineers intended and almost eliminate the boot/shaft failures

Totally agree with this. Given that +34" tires fit without a lift why risk the driveshaft failure by increasing the suspension height.

For those that just want the monster truck look (you know who you are!) , disconnect the front propshaft and pootle about in RWD!

I recall reading that. I’ve seen some pinions rather erect. I think the ring gear at speed is tossing copious amounts lubricant up and over. Ever wonder why they take the time to shape interior in a channel? It aids in directing the fluid up and over the top and not just splashing outwards to the side. I honestly don’t think a few deg of angle is going to prove to be life or death to the pinion, if it was, this was designed on the razors edge of reliability.

Just skinnies, which, contrary to popular belief, do not perform as well as true 35x12.5” inch wide tires.

I prefer skinnies and believe they perform better than 12.5" tires in my local conditions. But everyone has different needs. And has been said many times here on the forum by multiple individuals, just increasing spring height does not increase tire clearance. You can still compress the axles to the OEM bump stop locations which means if the tire rubs with the OEM springs it will still rub with taller springs when fully compressed. To properly lift a solid axle vehicle for increased tire clearance you have to add extended bump stops and ideally extended length shocks to make up for the reduced suspension travel that results from the extended bump stops.

What about a more robust Rzeppa at the front transfer case location.
I thinking when Ashcroft Transmission engineers built the oversized front CV’s on the Discovery 2.
Just an idea.

Never seen those before, cool product! Wonder how far they can bend?

LR put them in the rear diff end on Discovery 1’s and RRC’s. Most were replaced with u-joints at the first opportunity.
