  1. 20" Inch YOKOHAMA GEOLANDAR A/T4 | LT275/65R20 - 126/123S - 53.4# - 3PMSF

    Update on these tires. Had them on for about 12k miles now. With more varied driving average efficiency did jump up to 2.1, so about 5% less than the OEM Pirellis (efficiency with the Pirelli was 2.2) which I'm fine with considering the level of traction these provide. So far no vibration or...
  2. Clunking sound from front end.

    Ah! I did not realize our CVs had that center section. That would explain how they can telescope and adjust lengths to all the different ride heights. I was wondering how the hell they were able to accommodate such crazy axle angles, but the telescoping axle helps mitigate that. There is more...
  3. Clunking sound from front end.

    One more note on CV Axles, are you guys able to see what PN you have? Supposedly a few other trucks were fixed by replacing the CV axles with a new PN. That PN is PT00055489-C I checked under my truck and it's the same PN with -E, instead of C. If Rivian does part numbering like other large...
  4. Clunking sound from front end.

    It sure seems like there are numerous variables going on here. I don't believe all of us have the exact same issue or at least varying degrees of it. Mine seems to get louder once it's cold. But it also depends on the road/speeds I'm driving at. When I first picked up my truck from the SC, it...
  5. Clunking sound from front end.

    Damn.. so disappointing. Have you actually tried pulling on your CV axles, do you hear the same noise? I'm wondering if when the techs put the R1T lift with the suspension drooped out that it preloads the spline joint enough that they can't get the same movement. I've noticed on my truck that...
  6. 20" Inch $370 - Open Country A/T III EV | 275/65R20 116H tires now available

    I was eyeing these also vs. the E rated version. I noticed though they have less tread depth than the E rated tire. From toyo's site: That's about an 18% difference in tread depth.. Also to note many of this tires competitors (Yokohama, Nokian, Falken etc) have 18/32 depth. Makes me wonder...
  7. Clunking sound from front end.

    Damn.. I'm sorry to hear this. Are they sure there isn't something obvious rattling around? Do you have the underbody skid plate? I've read others saying there were loose fasteners on theirs that just needed tightening.
  8. Clunking sound from front end.

    The steering slop is interesting. You likely have a suspension piece or tie rod that's loose also. I'm not sure how the steering rack is mounted on the Riv, but I've had a steering rack loosen up on my Raptor and you could definitley hear/feel it in the steering wheel. It probably sounds pretty...
  9. Clunking sound from front end.

    Well damn. Compromises must always be made I suppose! Hopefully the full CV axle, not just the CV joints for solid axles are better. I know lots of Raptor owners ran them and don't recall hearing of excessive noise. I did find some info on the CV axle PN. This is taken from a Reddit forum so...
  10. Clunking sound from front end.

    Nice. I'm hoping this takes care of my noise as well. I may get my truck back today and will report back. It's amazing how much proper torque can affect play and clearances. It can be as simple as a torque wrench being out of calibration, run down (frictional losses) torque not being...
  11. Clunking sound from front end.

    Right. I do hear some limited squish/squeeling noises on suspension compression, which I'm sure is related to the air suspension, but I'm not sure it's realistic to have an air suspension be completely quiet so I'm willing to tolerate that. It rides/handles great as is. The potential play in CV...
  12. Clunking sound from front end.

    You're right. I read that wrong. Viscosity is the resistance to shearing/flow so more is thicker!
  13. Clunking sound from front end.

    I have not had a chance to read this entire thread, but I think there are two (at least) service bulletins that may be related to the "clunking" noise. I believe the clunking noise is usually the CV axles having some lateral play. My theory is this play only reveals itself at low speeds, where...
  14. Clunking sound from front end.

    Don't you mean less viscous? ie thicker? Cold temps generally make liquids and greases thicker. I could see how that could dampen some of the noise..
  15. Alignment through Rivian Service center???

    I just tried to have my local SC check my alignment on my truck and they refused. I just got new tires installed and noticed a bit of feathering on my Pirellis. The SC is saying they can't do an alignment on "aftermarket" equipment. Considering all the alignment measuring tools attach to the...
  16. 20" Inch YOKOHAMA GEOLANDAR A/T4 | LT275/65R20 - 126/123S - 53.4# - 3PMSF

    Sorry, been busy and wanted to get at least 1000miles on these before updating. So far they are great. There is a slightly different tone of road noise than the Pirellis kind of a lower hum tone, but it's not obnoxious or even noticeable if you have music playing on low. Efficiency #'s are...
  17. 20" Inch YOKOHAMA GEOLANDAR A/T4 | LT275/65R20 - 126/123S - 53.4# - 3PMSF

    Dang, those are an awesome price too. I only see the 60s though. You havent' found 65s have you? I have the 65s on my truck, wanted to keep all the ground clearance I can get for super deep snow days and some occasional offroading..
  18. 20" Inch YOKOHAMA GEOLANDAR A/T4 | LT275/65R20 - 126/123S - 53.4# - 3PMSF

    I did actually order the Firestone Winter Force with a separate set of wheels for when it gets real gnarly. Unfortunately the wheels are backordered. I know hakkas are great tires but they seem crazy expensive for a tire I'm only going to use for a few months of the year. I don't want to keep...
  19. Tapping out as well, goodbye Rivian...

    Also a reduction in stress levels ?. I park my Jeep wherever it will fit. Drive it partially into snowbanks, park right next to minivans etc. Half of the jeep is exposed tires and plastic replaceable fenders, the other half is rock rail and steel bumpers. Go ahead and ding your doors on my jeep...
  20. Tapping out as well, goodbye Rivian...

    Yep. I think you are on the right track getting a '24. There are screaming deals on them right now. I'm actually considering trading in my 22 on one because the warranty is almost up, and it will have the "safe" battery and new locker sensor design not too mention a few other niceties. I am not...
