The comment on dirty / rough running linkage is a good one. I lubed mine and clearly noticed afterwards that they were running much smoother (also without the squeaking noise).
Recommendations:
(1) try manually if they run smoothly, lube them properly
(2) swap actuators from left to right bank, see if the failure follows the actuator
(3) i think you will generally a new actuator for bank 2 as well, so go buy a new one and do step (1) also

I don't recommend changing both at the same time for no reason personally. Mine failed 30k miles/48k km apart. There's absolutely no reason to waste $600 if it's not needed in my opinion.
Once you've done this DIY once, it should be much quicker the next time around. For what it's worth, my second TVA failed at 88k miles (I saw no signs that it was replaced before warranty ran out on the car), so sometimes you can get lucky.
