I have a 2006 kia sportage and while driving has a loud rubbing noise from the rear end drivers side. It almost sounds like the tire is rubbing but I don't think it is the tire. Please help.

SOURCE: how to check front bearings on 2000 kia sportage

hi there, there are two ways to check your bearings, 1, is to jack up the vehicle so the wheel is free of the ground and to check for any play or roughness in the bearing by spinning the wheel, if the bearing is worn then you will hear a droning noise, 2 is to drive along a quiet road, at a speed where you can hear the noise, gently turn the steering from left to right so the vehile load is being shifted from one side to the other, if you have a wheel bearing fault the noise's pitch will alter,hope this helps

Your Tire Pressure Management System is extremely sensitive. Some makes are known to trip with just 5-8 psi. difference. Have the pressure checked again on all tires including the spare. Make sure the spare is up to proper inflation. VERY important. It is possible that the sensor inside the tire as well as any wiring associated with the system under the wheel wells could have been damaged. Start by making sure the pressures are all within system range. The owners manual will stipulate this and all info you may need to troubleshoot on your own. good luck.

SOURCE: Rubbing or grinding noise coming from Driver side rear tire/wheel

I had the same problem that based on interner research is common for Fords trcuks/suvs. The common problem fro rear humming "rubbing"sound might be the rear wheel bearings/seal. These will need to be replaced as it will progressivly get worse and the noise louder and eventually the bearings can sieze. I would hesitate to take to a ford dealer if I were you as it can run $500-900. Take to mechanic that knows how to replace wheel bearings and seals. My mechanic replaced them for about $150. and the bearing and seals are around $40. A good way to test this is to raise the wheel were you can freely spin by hand...if does not spin or there is a lot of friction then it might be the wheel bearings.
Good Luck
