Hello All,
I have had a 2006 GS300 for a few years now and am up around 125k miles. I have had a slight noise, revolving sort of clicking sound, coming from the front left of the car. I thought it was brake related, and have replaced the pads, rotors, and now the caliper yet the sound still persists. It has gotten worse as of late, and seems to be common on smaller bumps, and at speeds lower than 15mph. I have replaced the stabilizer/sway bar link, not that. I also have checked all ball joints, and there does not seem to be any play in the strut, although I am not ruling out the shock absorber inside. My next thought is it could be a bad bearing or joint in the CV axle. Is this far fetched/has anyone seen something similar?

I am basically looking for any guidance, as I can replace all components myself but am having a hard time diagnosing and don't necessarily want to shell out $170/hr for diagnostic labor to my local Lexus dealer.

Any help is greatly appreciated!

I would bet bearing based on the mileage and the bearings tending to go bad on these cars. If clicking, then the CV joint, but I can't see that failing unless the boot failed? Also check th tire, my irregularly worn tires caused me to think the wheel bearings were bad, and were actually louder than when my actual bearing went out

If you have a gopro camera strap it to the inside of the wheel well and video tape the suspension you might be able to capture it on video. Or take it to a good independent alignment shop many will do it for free in hopes of getting your business

That is good to note, although not sure where the suspension related noise could be coming from on smaller bumps? Unless I have a strut issue and wheel bearing for the revolving. Weird part is it tends to quite down when I put the brakes on. I did noticed the boot was loose and grease had leaked out of the axle last time I worked on the brakes, could that hint at something greater?

Maybe its the brake dust shield rubbing on the rotor, pull the wheel off and make sure they are not near each other
