07 LS460L Brake Issues
Just installed new OEM brake actuator and brake booster... The technician tells me that the brake actuator is constantly on/running while the car is sitting still.. Also says the yaw sensor outputting voltage almost as if the car is in a spin or out of control.. Anybody ever experience anything like this with your LS460???

It looks that there is air or a leak in your brake system. Ask your technician if he/she used Techstream to bleed the brake system per Lexus procedure for replacing brake actuator. Often, small indy shops don't follow Lexus repair procedure to replace brake actuator and pump, resulting in air in the brake system. Then, the brake actuator constantly attempts to adjust the brake fluid pressure (the long clinking noise from the actuator). You could ask your technician to follow Lexus repair procedure to do the "replace brake actuator" bleeding procedure. Most likely, the problem will be fixed. Good luck.
