Haven't had much time to work on the truck, did Jack up the front and check both front wheel bearings for play, they felt good. I spun the wheels as fast as I could by hand but couldn't recreate the click.

 

Does the 'clicking' noise happen at tick over when stationary when the engine is hot after a run? or is it only present when moving and speeds up with the truck road speed? Does it 'click' if free-wheeling in neutral? find a hill and try it out but FFS don't go into P park, go from D to N.
