I have had a similar type of thing.... I think? It turned out my Auto hubs had not disengaged and although I was in 2wd I was still locked in 4wd. Worth a shot. You would not likely feel this vibe offroad so may not notice.

It would take 5 minutes to remove the front shaft and worth a drive, you could be chasing a ghost mate.
Also as MudRunner has suggested!

I just remembered that My auto hubs played up with me in Tassie in 2005 on my 1999 4.2 turbo diesel Patrol wagon. I had a prick of a grinding noise going from 40ks to 80ks. The circlip had come loose on my drivers side hub and failed to disengage causing damage to that hub. I then replaced my auto hubs with manual hubs!

PS, good call MudRunner!
