Caster can be the culprit if the vibration gets larger with speed. Also was a road-force balance done? Any irregular tire wear? There are other causes, but check the easy (and more common) things first.

Too much caster can cause vibration. The reason is that the self-centering force can be so strong that it causes the wheels to continually correct. This isn't all that common, but it can happen on occasion.Alignment does not cause vibration. Caster is the angle of the ball joints this does not cause vibration. Caster can cause pulling or pour handling.
I think people are confusing acceleration shudder and wheel vibration, also mixing up the Model X and the Model S. My Model X also suffers from the hard acceleration shudder but does not have a wheel vibration while driving at highway speeds. Tesla is aware of the acceleration shudder and has replaced 1/2 shafts for many people (including myself). This seems to fix the problem for a while but it will come back. We'll have to wait and see if engineering can come up with a better and more permanent solution.
I don't have an acceleration shudder but the steering wheel continually vibrates to the point I hate holding it at highway speeds
Thats exactly what happened to me. I started to despise driving the car over a certain speed and it turned me off of Tesla period during all the time it took mis-diagnosing, testing, balancing x 3 etc etc. In the end after all the work was done i ended up with a new rim (replaced warped rim) and a new tire (replaced a feathered tire) and it's all fine.
I'll never know if all the work they did changing half shafts, engine mounts etc was actually beneficial or not.
Move the tires front to back first and see what happens to the vibration. Get them all balanced and again ask the SC tech to pay particular attention to whether the rim is warped, out of round or if they detect any tire hopping while balancing. Also ask them if the balance is a road force balance. If you have a second set of rims/tires, try putting them on and drive/diagnose as well.
Now that I got my car back a few days back, I'm as happy as the day I first took delivery. She drives like on day 1!
I can't imagine pulling to the left (or right) is "normal". Maybe take it to the Mississauga or the new Oakville SC.With the Model X, you can't move tires around as the rears are larger than the fronts.
I actually noted an issue where the car pulls towards the left, so I asked Tesla to do an alignment, and they noted the alignment was fine they did it anyways, and they noted the pull towards the left very slightly but said it has to do with a "Torque" issue which cannot be corrected and is "normal". I'm wondering if thats linked to this vibration.

I started noticing steering wheel vibrations at high speeds immediately after getting a tire rotation done at Tesla on my RWD Model S. I asked them to rebalance the front tires, but it didn't help much. I'll try disabling the lane assist and see if it helps, otherwise I'll just take it to a regular tire shop and pay for a balance on all four tires.
Do you think that's the nature of the wear on the RWD in the rears, or would it likely be an alignment issue?I'd check the front tires for uneven wear pattern or feathering. One of my tires balanced perfectly but when placed on the balancer, one could see the tire hopping slightly and worn unevenly. As soon as I changed to a new tire, it was night and day.
Balancing will ensure equal weight distribution but does not prevent a feathered or worn tire wear from causing vibrations. Also since your fronts were at one time the rears on a RWD, I would imagine they were subjected the full gambit of torque and power at all times...perhaps even some slipping etc.
