hello folks
i have the same problem with my is300sx 2002
i initially thought it was the driver side rear wheel bearing, so i replaced the complete hub assembly, however, the old hub was fine and the noise persists.........
today, i removed the disk and pads, the pads appeared to be binding in the disk slightly, so i cleaned everything up, copper slipped everything, took it for a spin and guess what, its still there!
for now, it looks like its the front hub/bearing, i have a 2nd hand 1 to check it with tomorrow
