Front drive shaft broken

[parb]

I'll hit 10k miles on the Teraflex today. 30k on the Grenadier.

Do you have a lift on yours?

Do you have a lift on yours?

yes, ~7000 miles with the lift when the driveshaft failed

yes, ~7000 miles with the lift when the driveshaft failed

This is approximately what I had when mine failed.

So you have about 3k on the Tera joint then? Again not far off from me. I'm just about to break 10k miles.

installed Teraflex at 20k miles, hit 30k today. installed the lift at 13k

Nice, that's good info.

Sounds like the teraflex worked out better than the factory for those with lifts.
Small sample but encouraging.

Have any new production cars been delivered yet? Production started a month ago so some should be showing up. I’m very interested to see the new CV they claim to be using.

I ordered in July and was assigned a VIN 2 weeks ago. No delivery date yet, but I'll make a post when it's delivered if someone doesn't beat me to it.

I get my QM at the end of the month. I'll take pictures. Might not be a fare comparison in the back. The front should give you a good idea since it will be the same.

Replacing the joints is fairly inexpensive. And the benifit of doing it preemptively is that the replacement joints are able to be easily replaced in the field. The stock joints are crimped together and require a fair bit of additional work to change them. Get the hard part out of the way in your garage so you don't have to mess with it on the side of the road.

The Tera joint has a very soft supple rubber boot. The stock feels much more rigid and more like plastic.

On a lifted Grenadier, is there any consensus on what is likely to be the better fix for geometry. Tera joint or a suitable drive shaft replacement?

Currently the only real option is the Tera joint at the transfer case. That said we really don't know that the stock joint won't hold up if it's treated properly when installing your lift.

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.
