I received mine as well.
There are many descriptions on changing the filter but it's so simple on the Rivian compared at least to most Teslas and other cars I'll describe it. Simple pull up the cowl cover; no tools needed.
Slide off the plenum. Notice I'm another victim of Rivian's poor...
I don't think they are going to switch away from trakmotive shafts. They are probably the only company that makes something that would fit. I think they could go to a better design with a larger spindle nut and rivian could revise their hub/upright with stronger material that doesn't deform.
Low ride height is least stressful. Launches are hard on them particularly if the steering isn't straight when you do it. The splines get a little knurled allowing movement which causes the back of the CV to squeak or tock against the hub.
A complete failure is unlikely unless you are abusing...
I also went with those and couldn't be happier. They absorb bumps, are quiet and I haven't really seen an efficiency hit. The PZ Sport corners better than an AT but they seem fine even on mountain roads.
2679lb tire rating =10700 lb
Vehicle weighs 7000 lb
cargo 1641 lb
So plenty of margin for...
I was in the mountains over the weekend where there's intermittent cell and it died completely. Activate and it listens for two seconds and turns off. No local commands work as it doesn't listen at all. Got back into cell service in greater LA but it was still dead. Maps and all other data...
Since the other three wheels articulate as well, they apparently can. I can't count the number of times I've been 4wheeling off road and lifted a wheel.
Something was left open or on or something like the seatbelt plugged in or who knows but losing 65% in five days, I would check how many miles were driven.
As an aside, I've noticed quite a jump in efficiency if I turn off the heat/AC. All of a sudden I basically get EPA. Surprising that it uses enough power to be so noticeable. Then I get hot and turn the AC back on lol.
