I've had this problem since I first got my GS. I get a clunk like a ball joint type of noise is coming out of its socket and then going back in.
It only happens when going in and out of a parking spot or like when you reverse to drive; basically it feels like when I apply the brakes that my pass side caliper it 'activating' before my driver side does. I've changed out:
- All new f+r brake pads
- All new f+r rotors
- New oem brake fit kits both front and rear
- New slide pins on the calipers (both front sides)
- Front sway bar bushings with daizen bushings
- Rear sway bar bushings with daizen bushings
- Front end bushings with daizen bushings
- Steering rack bushings with daizen bushings
- Brand new lower control arm #1's on each side with daizen bushings
- New upper front control arms
- New front outer toe control rods
- New front lower ball joint
- New inner tie rods
- New rear adjustable traction rods
- New rear adjustable toe rods
- New tires and wheels (no sign of camber wear)
- New lug nuts; conical style
I can't even remember the rest but basically most of my parts are brand spanking new. I even have new parts in the rear. I changed out my suspension with full coilovers, etc.
I realized when I changed my brakes the noise went away for a bit then came back.
I've tightened all bolts to spec using lexus manuals, etc and still have the issue. I've read alot and some say its a floating caliper/braking system design and that the stock/oem pads are made to counteract this.
I'm going to check it one more time before I sell the car because its driving me insane.
Any tips?
I don't plan to take my car to a mechanic because I'll hear the same bs spiel about how I need to re-change the same parts.
