Fix for Front Wheel Knocking: Think it could be the half shafts

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

A friend got a call from Rivian service and they said there is a fix for the front wheel knocking many owners experience at low speeds. They will be adding it to his ticket for late January. I’ll update once his truck gets back.

My friends R1T has a noise that's rather annoying in the driver side front. His daughter drove it the other day and said "what's all that racket?". A previous work order said the noise was normal and I think I have heard it in several other trucks. There is a bit of pay in the half shaft on the driver side both in/out and up/down that is not present on the passenger side.

His wife's 2023 R1S would make clunking noises over certain bumps but the R1T does it pretty much all the time and it does seem to have gotten worse recently after the suspension software update in 2024.19. Surprisingly, they've never been off road other than gravel/dirt roads.

If it was suspension though it would be there when you hit speed bumps and it's not. It was only noticed when over uneven road surfaces that causes quick oscillating in the suspension.

I have a feeling that it is normal after the parts wear in for there to be some noise but that doesn't make it any less annoying. My instincts keep telling me it could be the half shafts.
