wheel bearing if noise only while driving?

Whining sounds come from diffs that have a problem in the mesh between the crown wheel and pinion If yours is not front wheel drive then the noise may be from over tightened wheel bearings or failed bearings or the abs sender touching the exciter

Whining noise is probably in one of the pulleys or belts. Probably the power steering. And the popping is probably CV axles.

that sounds right

There are a couple of things to cause metallic sounds when turning. First thing, is if it's a clicking sound when you turn, then you have a cv joint going bad. It's usually more prominent when moving in reverse, however it can happen just as well while moving forewards. Secondly, if it's more of a grinding or scraping noise, we have a couple of options. The sound could be coming from the brakes, if they're worn or have grit stuck in them, or it could be bad bearings in the front wheel hub. The wheel hub has a tendency to making a whining noise when driving; usually most easily heard when driving past buildings. They can also allow the tire/wheel to present the appearance of leaning when looking at it. If bad enough, it can even rub on the brake caliper, or cause the disc brake rotor to wear out the brake pads prematurely. So, to recap: Check:
CV joints, if a clicking sound brakes or wheel hub bearings if grinding or whining sound.

Hi,
If the sound is coming from your power steering pump and the fluid level is good, the pump could be going out.

the suspect part for a power steering whine is the power steering pump, flush (very important) the system and replace the PS pump..

Dealers had alot of front differential bearing problems.

It could be chopped tires or a front wheel bearing. Rub your hand around the front and rear tires and see if they are un-even like a wash board. If they are they need replacing and will make a wierd whining noise that changes with the speed.The wheel bearings can also make this noise so check the tires and go from there. I hope this helps you.....Dan
