I have a 2010 Ford Fusion SE, 2.5, 225000 miles. I started noticing a grinding sound whenever I would take off from a stop and make left turn. Then I started noticing the noise whenever I would just start to accelerate from a stop, but it seems to stop after I get moving a little faster. Whenever I make right turns, I don't really notice it. The grinding is worse now on left turns too. I have ruled out everything with the right side suspension, everything I read said check the hub, cv joint, check for rubbing, it all seems fine. I'm kind of lost now and don't know what else to check. 1. Grinding noise coming from under the car, center/rightside. 2. It only happens after the car has warmed up and been drove a few minutes. 3. It happens when accelerating or making left turns 4. When I hear the grinding, I can let off of the accelerater and the noise stops, which kind of tells me it not related to my suspension. Any help appreciated, Thanks!

First off, I've tried searching multiple fusion threads but I havn't come across any similar threads with my same specific issues. So i'm hoping i can get some ideas on a diagnosis. I've taken the car into the dealer before on the issue, they blamed the worn out tires and sent me on my way (I've replace those now with zero change on the issue). Here's the quick explanation: The faster I go, the more I hear a hum, vibration, and now more recent a hum/vibration/grinding sound coming from the front engine bay of the car. I've been trying to diagnose it for awhile now (i'm fairly car savy) but this one stumps me. Here are a couple points that might help in diagnosing the issue: The noise is directly related to the speed of the car and the input on the gas peddle. When above 45MPH I start to hear the hum/grind of the noise above the regular road noise and it is progressively more noticeable as the speed increases. Between 80-85 MPH the hum/grind noise hits its peak and sounds like it resonates with the resonating point of the car. Its as bad as a high revving 4 banger with an exaust leak. At all speeds I can press and unpress the gas peddle to momentarily make the hum/grind noise to go away but it will then return after half a seconds time. If I leave the peddle press or unpressed(decelerating in the process) the hum/grind noise is constant. Forcing the car to change gears has no effect on the pitch or sound of the hum/grind noise. "Only the speed and gas peddle inputs change to pitch and momentarily make the hum/grind turn off for a moment" Things I believe I've ruled out: Out of balance tires or rims, breaks or rotors. Driver side front wheel bearing (replaced), I don't think its the passenger front either (No change in noise by harsh steering adjustments) Things I'm worried about: Drive train? Half Axles? Transmission? Engine mounts or linkages? Intake or exhaust issues? Turbo Issue? (I still have great performance tho) Any thoughts? Those are some potentially BIG and EXPENSIVE repairs that would be above my DIY car repair level. So i've been reluctant to bring my car in for diagnosis but its getting worse and now sound more like a vibration/hum with grinding as opposed to more a hum/vibration like it was 5k miles ago.

Ok, so I am new here and figured I would start out with a issue I have run into with my 2011 Ford Fusion SE. So I bought my 2011 about a year and a few months ago and it is by far the best car I have ever owned. it was re-inspected right after buying it and all was good. So other then finding out my back caliper was bad 3 months in no issues and honestly it wants that hard to replace. Fast forward to today ... well a month or so ago. (don't peg me on the time I don't have a lot of cash to spare and I need bill paid first and no I am not driving it atm) So I go get it inspected and everything passes except the front rotors and front brakes! Yay me! I have done front brakes before about 30 times over the years. This is the first time on my fusion so I do a couple youtube video checks and noticed the need for the torque driver so I grabbed one and was good to go. Ok so they say rotors were rusted a bit and brakes needed to be replaced, no biggie. LIARS!! Rotors were rusted solid on to the spindle so 3 hours later and a sore shoulder plus hammer and rust penetrating oil rotor one is off and replaced. Jump to the next day same this for the other side except the torque was screwed up before so add in a power drill and a metal bit later that screw is removed. Add on top 4 hours later and again said sore shoulder and penetrating oil second one is off and rotor is replaced and brakes done. I back out of friends garage a little grinding but that's normal usually disappears in like 3 minutes max. So 2 weeks later and a lot of looking on my part and that grinding is still there and it is eating into the rotor little by little. HELP!! I can only think Calipers but odd and hell that 2 working calipers stopped working. HELP!!

My 2010 Fusion has been making a 'grinding' noise when turning left or when accelerating from a complete stop. Turning right I never hear the noise. I have had the cv joint changed and there is no play in the wheel bearing. It gets worse in low gear when compared to drive with the same road speed. The noise goes away at high speed. On inspection I found the transmission fluid to be low, so flushed some and replaced but the noise is still there. Suspecting a problem with the differential. Any tips on diagnosis? My local garage have failed to diagnose anything feasible finding other rattles and trying to charge me for fixing.
