Noisey front end?

Need some guidance here. I have a 1999 2 wheel drive ranger with 106,000 miles. My front end was always on the noisey side.? Sounded like it had mud tires on it. At 90,000 I had new tires & brakes put on it. They also replaced the wheel bearing and did a front end alignment. They said the wheel bearing where shot... After all this work there was NO noise. Truck ran great and was nice and quiet. Now 15,000 miles later it just got noisey again? What should I check? Could the wheel bearings be noisey? or could this be an alignment issue? Truck feels and drives fine. Just can't stand the noise....???

Might be bad ball joints. Jack the front up and take the top and bottom of each wheel and try to wiggle them. If there's play then they're probably shot. Also check the tie rods, and of course the wheel bearings.
