Problem discovered due to front end vibration over 60 MPH, car had very low miles 47,472 miles when vibration started. Vibration was coming from the left front wheel and a wheel bearing hum. So after inspection of the front end, discovered rubber cracks at forward control arm aft attach donut bushing (Basically deteriorated rubber at bushing surround). Car was also pulling to the right.

Big job to replace lower control arm on this car, the transmission had to be jacked up and one engine mount had to be removed to get access to remove the forward mount bolt on the Left control arm (Very poor design by Toyota/Lexus ). The half shaft on the left front replaced, front tires replaced along with the Lower Control arm.

Finally the car drives perfectly with no vibration or pulling to the right like before. Now with the front end issue resolved except for the bearing humming noise which is actually coming from the rear left bearing hub assy. which well be replaced as soon as I get the replacement part. I will update the left rear bearing hub humming noise when fixed. Toyota/Lexus you need to get better.
