I put my ute in 4wd the other day and when i accelerate there is a clicking noise come from the left front around the wheel some where. As i sped up a little it got faster. Then took it out of 4wd and no noise. Been about two weeks now and no noise at all in 2wd. I asked my mechanic to have a look and he said its the wheel bearing. Any thoughts what it is? Because im sick of paying mechanics to fix things with what they say and you still the problem.
