what is a wheel bearing(whats does it do) and where is it located...

okay i have my car on the lift the other day and i could spin my front passenger tire with one finger.. the driver side front tire took 2 hands to spin.. one mechanic saying thats bad.. another saying it doesn't matter... that won't affect nothing.. the other one saying thats bad said it might be the caliper.. well the car does squeak a bit until u press the brake then the noise stop i don't know if thats all related.. i know i've been asking alot of question lately but i'm trying to make my car reliable as much as possible.. and also learn as i go along.. doesn't hurt...

 

Normally there is some slight resistance when turning the wheel due to the brakes slightly dragging because of rust, dirt, etc. However, both left and right sides should act about the same. It shouldn't take two hands to do it. Your driver side caliper may not be centering. The squeek until you apply the brakes could be because the pads are loose or glazed.

The "mechanics" could have offered a better diagnosis after a brief inspection to narrow down the cause of the problem, if any. Worn brake pads, sticking caliper, and severly grooved rotors are easy enough to spot.

BTW, wheel bearings reside inside the hub of the part your wheel bolts to. When they go bad they typically make a growling noise when you drift to the left or right while driving. You may be able to hear them rumble when turning the wheel by hand. Replacement usually requires a press to remove and reinsert them, and a whole lot of disassembly to do it.

Part #2 is the wheel bearing

 

growling sound isn't pigeon or noise type sound right? thanks..

 

okay so one tire being hard to turn doesn't matter or its not a problem?

 

is it an issuse or no..

 

uh, no a growling sound wouldn't be a pigeon sound to me. A bad wheel bearing should have a humming sound while driving that normally increases as your speed increases.

One wheel being hard to turn shouldn't be an indication of a wheel bearing.

With the front of the car on jack stands, grab the tire on the sides and try to wiggle it back and forth. Does it feel solid? If it feels loose or wobbly, then it could be a bad wheel bearing.

no play in the wheels at all.. just one tire has a bit resistance to turn while the other tire has less and easier to spin...

 

if there is no play and no humming coming from that wheel while driving I would say it's not a wheel bearing problem.
