Hi guys, recently bought a 2000 LS430 - had no issues on the first few drives, however recently a knocking noise has appeared that goes up with speed. When applying the brakes, the noise goes away almost completely, and it sounds like it's coming from the front passenger side.
I've had the wheels off, checked brake pads & discs, all bolts and everything seems tight as far as I can tell. The noise started out of nowhere, and it's been the same for the past week or so, it hasn't gotten any worse. The only thing I saw missing is the disc retaining screws, but don't think that would cause the issue. The car is on sitting on BC coilovers. Tyres are all good, all correct pressure and no visible damage to them. Have swapped the front wheels with different ones, and the issue still persists.
Any idea what this could be? All help is appreciated
