Half-Shaft issue thread

[Jonger1150]

Will these things ever be replaced with an updated design or new supplier? I finally started getting used to the chatter at low speeds, I accepted that the sound was part of the deal with a suspension this complex. But..... now my half-shafts are starting to rumble/vibrate under acceleration.

At one point it was only when I FLOORED the vehicle, now the threshold for vibration rumble strip noise is far far less.

Making a Service center appointment with the aim of getting the front ones replaced.

If you have spent any time on any Rivian Facebook, forums or Reddit pages, you'll know Rivian wastes a ton of money on fixing and replacing half-shafts. I might be wrong, but I'd guess this is the number 1 replaced part on the vehicle.

Will we ever see a replaement part for this? Does Rivian get fully compensated by the manufacturer and they simply go along with it?

I get a terrible old car creaking from the half shafts on the front when coming to a stop and setting off from a stop. It’s just a grating sound to tolerate. I have a service appt next week.

 

[RivianRush]

This is what I am currently dealing with. Have an appointment next week. They stated they believe it’s the half shafts as well.

No way it should be making those sounds! Let's see if they try to claim "within spec"

I also have the half shaft slop and associated clicks clacks and toks. It has gotten pretty frustrating as at low speeds, it sometimes feels like every wheel has a mind of its own. The sound bothers me less than the sensation of delay between pedal input and each wheels output modulated differently by the half shaft slop. Have a mobile appointment in 10 days to look into it. Curious to hear what the service experience is like for others trying to address this.

I had mine replaced at no charge.

Just had my half shafts serviced. Tech said they didn’t need to be torqued only lubricated. After about 200 miles, the clickity-clack is starting to come back.

Did you have the vibration under heavy acceleration?

Not a lot of vibration under acceleration but hard knocking upon torque reversal.

Are you sure this isn’t a jounce line? I believe they have a TSB for that. My model X had to replace to have half shafts replaced. First time I heard Rivian having that issue.

I had that done. My issue is in standard height under acceleration.

Let me know what you find. I’m curious to see if there is a new manufacturer or design out there. Have them replaced. I’m about to endeavor with this shortly.

 

[Jonger1150]

I wonder if there could be an aftermarket part for this someday.

I'm sure that would void the warranty.

I'm new to the rivian life, but I have a bit of a rattle sound, in my imagination there is play in my half shaft. It happens just over small bumps in standard ap mode. No rumbles when accelerating though

That's normal. There is a linkage in the middle of the half-shaft that has designed play in it to accommodate the 7 inches of adjustment to the suspension. That's annoying, but the bigger problem is that they start to fail and will vibrate under high torque.

It's almost a certainty that Rivian has explored a new design or supplier for this. Zero word as to whether that's happening or not.

This is still the best vehicle I have ever owned.
