About a year and a half later, have an update worth sharing.
Last night, weather was great so put all windows down. Began hearing a clicking noise when turning right. Noticed at full lock, noticed also when just drifting to change lanes. Slight click when turning left.
I thought, crap - cv has gone bad.
Put the vehicle front end up, rotated and shook the tires...

Solid. Half shaft boots looked in good working order.
Noticed the SPC UCA boots were covered in grease and some 4R forum said greasing the zerks got rid of a clicking noise in the front end.

Well, called SPC and talked to one of their mechanics for 20 min (Mark). Mark was super helpful and walked me through how the UCAs work and other potential origins for clicking/noises from the front end - brakes, UCA bushing, UCA ball joint, and axle shaft.
Note: I’ll need to hit the zerks w SPC approved grease to keep the UCAs in good working order.
Ruled brakes out, bc noise happens on acceleration. UCA bushings, bc that’d be a more of a squeak. And UCA ball joint, bc that’d be more of a clunk and not a repetitive click click click.
Shoot, was back to cv. Started looking for the part online. Aftermarket - don’t trust. OEM - super expensive. Remanufactured - wasn’t having luck finding for the 200, tho 100 was pretty easy. Now I understand another value of swapping to the Tundra front end - easy to find Tundra half shafts.
This was beginning to look pretty grim.
Took it into Camelback Toyota, just to double check the diagnosis.
Turned out the culprit was... the spacers had come loose and needed to be torqued down. Only bugger is a missed opportunity to test out my new torque wrench. But, glad that was all the problem was. Easy fix, but could have been really bad left ignored.
I share the above in case anyone else could benefit from this experience.
