Hey guys

I have some FAINT clicking noise at the rear of the 08 LS460 and I'm thinking it's rear bearing going out..but not sure...what exactly does bearing failure sounds like? I hear this SOFT clicking noise from (more likely) the right rear. The noise is very faint and I have to roll down the window to actually hear it. If I move through the neighborhood at about 15-20 mph, I hear this clicking faint clicking sounds..and if I speed up a little, the clicking noise increases (in frequency, not loudness). When I go faster like on freeway or normal road, I can't hear it anymore. Probably clicking too fast or not as loud at that speed. With windows up, I can't hear it at all.

Is this has to do with rear bearing going out on me or possibly something else? Any recommendation where I can start looking at? Is it brake pads? The car is 35K miles but since it's 08, unfortunately it's out of basic warranty (time). Is this covered under powertrain? Thanks.

yeah normally clicking noises if your a turning are cv joints but that does not sound like the case it might be the brake pads when applying a low speeds (shims) or parking brake not disengaging all the way and need to be adjusted. kind of hard to determine since it is not me but with what I have experienced with different vehicles wheel bearings are loud when they go out and you will hear a whirling noise or something just loud enough that you will know it is the bearings, if you can try and a take a video and post it up.

Thanks. I'll check the pads. Hopefully it's not the bearing.

Go slow over bumpy road..hopefully close to a wall so you can hear the sound bouncing from it..slightly apply brake.. if it goes away, you need to replace the anti rattle clips for the pads. This happened to me..could be brake actuator..annoying noise but not considered as a detriment to functionality of brakes..dealers have replaced them under a TSB while within 4/50 warranty..that part is a couple thousand dollars iirc
