When I accelerate from a complete stop while turning left, there is a rubbing or grinding sound that comes from the back tire or wheel. I had my tires rotated today and the mechanic stated that i need to service the rear differential. Could that be causing the noise? He did check the brakes and calipers and those looked fine.
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
Yes the rear differential could be the cause if you have a limited slip rear axle. The clutches could be binding in the rear axle.This would be noticeable especially on turns and accelerating.
If you have 4X4 then you have a rear limited slip differential. I would try servicing it first and adding friction modifier to the fluid and drive it for about 100 miles to see if this corrects the concern first.
Looking at the back cover you will see a large plug on the lower left,remove this plug to drain the fluid.
On the top right you will see a smaller plug,remove this one to refill.
It will take 2.6 to 2.9 pints of rear axle fluid and 4oz of friction modifier.
You will fill it to 1/4" from bottom of the fill hole.

Do you have a lot of weight in the back? There is a plastic nub inside back wheel wells that will rub on the tire if it’s too heavy. I just discovered this when moving.

I don't know if I have limited slip, but i do have auto 4x4. I'm sure it will be expensive to fix.
i want to try to do this myself. Where do I start? Where do i add the fluid?
We have a 2002 Ford Explorer with the exact issue. We did repair the differentials and had the problem looked at a year ago at a Ford Service Center which has recently closed and which they claim to have resolved. Last Thursday the rear wheel broke while my husband was on the highway. Today we are hearing from the mechanic that it's the knuckle and when it breaks (and it will) they will tell you that they no longer make the part for older Explorers and in order to replace it with the current part you will also have to replace the axcel. I am in the middle of making sure this info is accurate. I will keep you posted. So far we are looking at $800 in repairs....Thank God my husband is ok.
It actually feels like its coming from the front, right under the driver side. I was told by an INDEPENDENT mechanic that my ball joints need to be replaced, however this sounds more like the problem I am having. Is there a front axel differential that could be damaged? Thank You.
Grinding or rubbing noise
Rubbing sound from left driver tire
never had front wheel apart. I swop my own tires Noise did not change If it was abearing I would think it would have a more distinct sound.
