Half-Shaft issue thread

[telero]

Started looking around for issues to potentially bring up as we approach the 60K mile mark. Started listening for potential half-shaft issues after reading a bit here and on Reddit. Somewhere I think someone mentioned listening for the sounds both while moving and by hand manipulating the wheels when jacked up. I took some video of both and wanted to see if what I'm hearing seems normal, or if this is a potential issue. Thanks.

I ended up mentioning the sounds to the Rivian Service Advisor while I was bringing the R1T in for another issue they found on a comprehensive pre-warranty expiration inspection. Took a quick ride around the parking lot and I think they were thinking it would just be a ting washer and lube/tighten things up. In the end I got new hubs and halfshafts on the front. I'm not sure if the rear was checked or not, and now I'm wondering if I should have specifically asked.

The replacement hub parts are HUB BEARING -WHEEL; FR Part# PT00031233-E
The replacement halfshafts are HALFSHAFT - FRT; R1 ORIGIN Part# PT00055489-H

Taking my 2024 in for 3 half shaft replacements later this month, as well as blown struts, and leaking air suspension, and a few other odds and ends.

They just replaced all 4 dampers, and half-shafts on mine. I'm greatful these things have been warrantable items, but I just had my rear dampers replaced in November. I think I'm on my 3rd set of front dampers, 4th set of rear.

Half shafts, I believe 3rd set on the front, 2nd set on the rear.

I asked what the cost was out of warranty for 4 and 4 being done at the same time, and was about 15k cdn/ 11k USD plus tax. I horrifically expected 23-25k cdn so better than I thought. I suppose that would be a worst case once every 2 year expense out of warranty due to the 2 year unlimited mileage parts installed by Rivian warranty.

One of the reasons I am glad I was wrong about the warranty. I thought it just had a 3/36.. I was glad to find out it was a 5/60

As someone who is quickly approaching out of warranty, what should I be doing about half shafts on a DMP? And what should I expect cost wise out of warranty, and how often?

Been researching the R1T and found out about this issue. Is this an issue that will deter someone from buying a R1T?

It didn't deter me.

It's a suspension that car corner like an exotic and also complete the Rubicon Trail.

The downfall? You have way more things that can and will fail.

That's literally the reason it's so hard to give up. I love the breadth of capability, but I hate that if 1 of 6 interconnected components goes, the whole thing needs to be redone.

The simplicity of the R2 suspension will be it's greatest strength, and should lend itself well to the aftermarket community.

I just hope they don't change the frame with new models. Improvements to the half-shafts and shocks should continue to happen as long as they're dumping cash into these repairs.

I just assume every knock and clunk I hear will be eliminated someday. Probably out of pocket though.

Who thinks it can corner like an exotic?

So, I've got a 2023 R1S Quad that I'd noticed clicking on about a year ago. It was originally diagnosed as a dashboard piece issue which was replaced and I moved on. It was mostly my wife's car which gets about 120 miles of interstate driving every day so I didn't hear much else about the clicking until I drove it again in a parking garage and it was awful!! I took it in for another diagnosis and they said the half-shafts were the issue and the dampers were leaking! The car had 70,000 miles on it at that point but only a little over 3 years. The serve tech manager said these repairs were not covered any longer as the vehicle was out of the milage range for the bumper to bumper warranty. I asked why this would not be covered under the drivetrain and he just said that it was not. I attempted to escalate to Rivian through contacts at HQ and they referred me to their "[email protected]" email which has received no response.

This is an absolute abomination for a new car company to treat it's initial adopters this way. Has anyone here been able to contact someone at Rivian to get this issue addressed under the drivetrain warranty?

It's unfortunate for sure. But their comprehensive warranty terms are very lax in comparison to others, with Rivian covering literally everything while within the warranty limits.
That said, the half shafts unfortunately aren't considered part of the drivetrain warranty, which to me is a bit of a grey area in their terms. I'm not super familiar with other OEM drivetrain warranties, but I would assume it usually just covers motors and transmission, not output shafts or axels.

If your state offers Rivian or Xcare, I would look into that prior to having the repair done, could save a fair amount, in spite of the upfront warranty cost.
