Houston, we have a problem. Its the CV boot. +Mossy Houston Update

[GN4HIR]

Do we have a poll, list or some other tally of how many CV joints have gone to that great drivetrain in the sky? I need to get on that list. And, maybe that list needs to go to NHSTA.

Mid March, in preparation for the long drive to and from Moab, I had Mossy Houston put my factory springs back on and install the full Rival skid plate package. If there were any signs of CV trouble, they certainly would have seen it and said something.

Last week I crawled under the truck to see where I'd made use of the skid plates. I hit a couple of the control arm covers, rode my driver side rock slider a bit, and slightly dented and scraped my front factory skid plate. Nothing too serious, everything did its job. I do need to rattle can over some of the wounds before they rust.

However, when I reached up and around the skid plate to cop a feel... I was shocked to find the rubber had broken and spewed out its contents. Yes, it was the CV boot, front driveshaft, T-case side.

I texted Trevor at Mossy. He got me in and out mid March in a day, certainly he could fix this ASAP. No reply. After a couple of days, I called Mossy, only to learn Trevor was gone. Greg is now Service Director. The guy I spoke with asked me if my truck was lifted as Ineos was denying those claims, he conferred with a Tech who asked if my CV was making noise (it isn't), and then told me I shouldn't drive it and they can't fit me in for a week or more. I explained this is my daily driver. Greg has emailed me to say they will see what they can do.. and so I wait. I failed to ask if they had driveshafts in stock. They did tell me they couldn't fix my cracked windshield for at least 3 weeks when more are scheduled to arrive.

The backup in service may (I hope) be temporary as Greg just took over and I'm sure their is some disarray in service. Time will tell.

Rusnak Pasadena is replacing mine as I type. No 12,000 and no lift. It does have a fair amount of miles on dirt and has been well articulated. I'll start the pole if I can figure out how to do that.

Front driveshaft, transfer case cv boot was just replaced by Sewell. By that, I mean the entire front drive shaft was replaced and had to be shipped from EU. Took about two and half weeks to get approval from Ineos to warranty the job and get the part.

Daily driver, no lift, 15k miles, maybe ten hours off road but nothing hardcore.

I think it's wild that I can buy replacement boots and fix this myself, but that it voids the warranty if I do.

Forgot to update this.. I did get in to Mossy, they gave me a loaner. I knew they had a driveshaft in stock but after a week, I called to see what was the delay... well, they had to send info to Ineos (about suspension and tires) to get a warranty approval. Once that was approved, it was out in a day. My failure happened on stock springs, 33" tires, at 15.5K miles, almost all of which was on road

How would they know, the terra joint is virtually identical and once dirty from use the only distinction is that the back half is not crimped on. Regardless, I'd pay $175 for a new joint rather than have the truck sit for weeks at the dealer. The new joint wont void any other warranty on the truck anyways.

Use the stock bolts if you want to keep it looking factory.

So is the CV boot failure now basically a guarantee? If so I would assume more people would be complaining about it in the forums since at this point probably 15,000 grenadiers have been sold?

So 33” tires pass the scrutiny test. What about 35”?

No, it is not.
If you have a lifted vehicle, your chances of a failed CV boot are higher than stock but your chances of having a push back on a warranty fix is much closer to 100%. You carry your own risk if you modify your vehicle.

There appears to be much noise and fury about failed CV boots, but aggrigating this forum's posts and the noise on FaceBook I'm seeing, I'd guess no more than the low hundreds as there are 68 entries on the forum thread, (https://www.theineosforum.com/threa...-driveshaft-cv-joint-failures.12420239/page-4), and some of those will be duplicated on the forum thread and on the FaceBook entries.

Back when I worked for a warranty provider, it took a lot of common failures before the authorites would act and the manufacturers conceed, even for a safety item, think in terms of 10% of the model population.

They replaced mine under warranty with 35” tall tires. 255/85r17

Behind the scenes though, I’m sure Ineos Automotive along with parts manufacturers like Dana Spicer will be looking into the prop shaft issue. . There are just not going to announce anything publicly.

I hope they are but I doubt it. If a solution was available, it would have been be available in other vehicles many years ago.

The solution is not a change to the drive shaft but a change to the front axle housing. If the pinon is rotated up in relation to the knuckles then the operating angle of the driveshaft will be reduced. This could also allow for more caster angle which will improve return to center and straight line stability. So the vendor in question is Carraro not Dana.

What about the angle at the transfer case then? It's my understanding that the angles on each end need to the be about the same.

Raising the pinion will also reduce the angle of the drive shaft at the transfer case. The angles on both ends do not have to match. They just need to be less so that that the boot on the CV joint no longer fails. If a single u-joint were used on both ends of the shaft then yes the angles would need to match. But the likely hood of them switching to a u-joint design is nearly zero.

Not with CV joints.
