Hi All, Newby with a weird problem. I have had a look through the forum but come up empty so will post issue. 06 dual cab 4x4 turbo diesel started making this wup wup wup noise and self diagnosed front wheel bearings. Anyhow $800 later with new bearings (hubs) the noise is back. Admittedly it went away for a day after the bearings where swapped but returned within a week and is as loud as before. It is road speed related and not engine speed. Guy who did wheel bearings cannot work out what is wrong. He's told me that it seems to be every 4th wheel turn (?) meaning it's not the tyres. Does not change with different gears so doesn't seem to be gearbox/transfer case (could be wrong there). Starts to come in at around 50/60k and stays up to 110k increasing frequency with road speed. I can sense it through the steering wheel and mate said he felt it through the cab floor drivers side front but I couldn't notice on the passenger side. Suspect cv joints or is there a bearing on the drive shaft? I was told the drive shaft turns 4 times for one revolution of the wheels so this would count that out. I have run out of ideas and wondered if anyone else might have had a similar experience. Would love to hear comments or suggestions. Cheers Phil
