I think it’s a PAO and Ester base full-synth. But you’re correct, it’s not hygroscopic.
Steering wheel shakes going over potholes, is this normal?

I noticed this phenomenon when I first got my '18 in stock form. When I took off the stock 21's and put on 315/70 and then 37x12.50/17 I noticed it less in general highway and dirt road driving. However when hitting rocky trails I definitely feel and even hear this translating into the steering wheel. Could this have anything to do with the VGRS (variable gear ratio steering) system?
I had my brakes done several years ago around my 60k service and while towing down the mountain quickly warped the resurfaced rotors the dealership turned for cheap. Ever since then once the brakes get heated up during daily driving the warped rotor experience seems to feel very similar to the steering wheel shake or twitch I call it. Having experienced this to the Nth degree now for quite some time I am wondering what the solution is.
To explain it further if I hit a pot hole with the driver side tire the steering wheel will quickly twitch to that side. I understand that some of that and the suspension doing the same is normal. But it is being exaggerated somehow. I can equate the feeling of the twitch to that of an extreme angle on a rear panhard bar of a Land Cruiser and going over a speed bump and feeling the "side twitch." I've experienced a steep rear panhard angle for 15 years on my 80 series and then corrected it to be nearly parallel to the axle and know how it's supposed to feel. I have a tendency to tinker $hit to death, but having heard this complaint from a few people local to me I don't feel like I'm reaching to look for a solution to this.
Would installing a steering stabilizer fix our problem here? I've never seen one on a 200

Does the 200 have a standard rack and pinion steering rack? Would the stabilizer be installed somewhere there or on the steering column?
True. Stabilizer won’t work and shouldn’t be needed.
For what its worth, the GX460 has a steering wheel damper, while the GX470 does not. Both are rack-and-pinion systems. I wish my 470 had some dampening -- I prefer more detached steering wheels with less road feedback/kickback.

Hey, update time. So I took it to brakes plus for an alignment bc it was pulling a lot. They got everything into spec (I saw the printout) and the wheel shaking got worse and I was having to hold the wheel to the left to get it to go straight. It went from shaking on potholes and manhole covers, to shaking on any little bump. Two weeks later, I took it to the dealer. They said the camber was off and they said they adjusted the steering wheel. It still shakes on big holes, but it is so much better after the dealer did its thing. So, how would an alignment affect the shaking? I still have not had the tires rotated. That’s coming this week. I go to the dealer Thursday for a 100k service.
Here is another tidbit, since I’ve been driving it more, I’ve noticed a loud high pitched squeal coming from the rear driver side when I turn the vehicle off and the AHC system sets or resets or whatever it does right after the car lowers and is turned off. I will have the dealer look at it, but it doesn’t happen every time. This is my wife’s daily, so I have no idea how long this has been going on. She said “it has been doing it for a while.”

Yes, it is correct. Do your research
AHC fluid is hygroscopic, just different characteristics for the system compared to brake fluid.
