I just bought my 2016 GX 460 with around 84k miles on it and im currently on a cross country trip from nevada to iowa. Before I headed out for the drive, I changed all the fluids in the transfer, transmission, differential, power steering and etc. also changed all the brakes, and got alignment and balanced the tires. i even changed the spark plugs to Denso Iridiums and greased all the u joints and yokes. However, I'm noticing a few issues with my car during the ride on my trip. Now, please let me know if im being too sensitive about these things. it is my first gx460 and i've never owned anything close to it except for my 2014 jeep grand cherokee.

First, I still have a slight vibration from the steering wheel and from the seat around 70-90 mph on the highway, the previous owner put KMC technic 18 offset wheels and new Falken Wildpeak AT3W with it. im not sure as to why im still having this issue. there is a slight "play" or a "click" per say when shaking the steering wheel left to right ever so slightly from the straight position. im not sure if this has anything to do with it but thought i should say it.

Second, when i hold the press the gas and hold the RPM around 1700 or so while in park, the vehicle starts to shake slightly side to side.

Third and the most annoying, I'm having this really bad phone vibration like under load especially around 1900 rpm or around 2300 rpm going 78 mph or so up hill which is the worst. but i do feel the resonating under any load mosts of the time. when it gets bad, it makes what i can best describe a "woo woo woo" repetitive vibration noise every other second at that 2300 rpm. im maybe thinking if it has anything to do with my exhaust or muffler going bad.

Fourth, not really that bad, but when the car starts cold, it got like this whining noise that makes more or less noise based on the rpm. kinda sounds like a power steering whine but when its warmed up, the power steering is really quiet when i turn end to end.

I know its a lot of issues to tend to in one post but id rather gather all the issues into one post so people who have similiar issues can come by to either provide a solution or get solution from others on this post. If anyone has solutions or opinions on what these issues are, please let me know.

A recording of your cold start whining noise would be helpful

Thanks, I'll upload a video when I get the chance.

get the wheels road force balanced. also might check out the alignment. can also check the wheel bearings.
check to see if the resonator is stock, and the rest of that system
could be a shaft bearing getting moisture and drying or rubbing until expansion
