Any mechanics here, I have a 2008 Edge AWD its making a very loud noise when driving down the road. Everyone I talked to said wheel bearing noise as it gets quieter when turning (right turns especially), louder with more speed. It's for sure coming from the front end. However I just had the bearings replaced on both sides even though they didn't seem bad. The sound never changed. The tire rod ends were also replaced as they had a little play in them. The noise remains the same. I was thinking maybe CV axels? but there's no popping sounds I am told is associated with it. You can barely hear it at low speeds and the sound gets increasingly louder with speed, to the point you can't hardly hear anything else. I don't want to keep throwing money at it and hoping it'll fix it, but I need to do something.



If anyone knows what it is, I sure would like the help.



If you have any further questions or advice on this issue, just let me know.



Also, in a possibly related question,,, there is a loud clunk when going from drive or park to reverse unless you completely come to a stop and pause for a second or two, then it doesn't do it. This has been going on for quite sometime, maybe a couple years, but the other noise has progressively gotten louder over the last few months. If you could help diagnose the cause of this I'd greatly appreciate it too. (engine mounts seem solid if that matters)



Thank you.

Not sure if you can hear it well enough, but maybe...

Sounds like wheel bearing

Definitely sounds like a wheel bearing from what I could here on the video. I would check the rear wheel bearings since turning changes the load on the rear bearings although not as drastically as it does to the fronts. Being load sensitive makes me lean toward a wheel bearing.

It's for sure coming from the front but I just had the bearings replaced and made zero difference in the sound. The old bearings weren't even in bad shape.

Rotate the tires

Sounds like a wheel bearing, bit of you had them replaced, then it obviously isn't the cause

. Regarding the clunk, it could be an engine mount, even if they appear visually okay. The passenger side mount (on what would be the front of the engine) on those engine will sag and grounds itself out so that it's basically metal in metal. When they get that way they make a buzzing sound that could possibly sound sorta-kinda like a wheel bearing, but it likely wouldn't change with side-to-side turning. That mount is easy to check, just jack up the motor and remove it, it'll be glaringly obvious. The mount on the trans can go bad too, but I didn't see those as much.

Is it all wheel drive? If so......the PTU (power transfer unit, aka transfer case) could very likely have failed. I replaced tons of them on police cars, which are basically the same drivetrain as that edge. They're tucked up under the rear catalytic converter, where they just roast in all that heat, and only half about half a quart of gear oil in them. The gear oil cooks and turns into a gelled sludge, and they make all kinds of grinding sounds, along with clunking sounds when shifting like you described.

It is AWD.

Has a transfer case - sits above the catalytic converter which results in the qt and half of oil to cook down to a sludge. Have them check that.

I had an AWD Subaru a few years ago that I thought had a front wheel bearing noise.

Took my mechanic for a ride after he looked at the tires. He was 100% convinced it was the right front tire. Very slight inside/outside edge wear on that one tire.

We both agreed that type of wear was probably caused by a worn strut. So I replaced all of them.

We have a Ford Edge. We changed the wheel bearing when we had similar noise. Quiet now. Ours is a 2011.

The easiest fix, just buy a new car.

A new wheel bearing shouldn't go bad so quick, but if made in China who knows?

It is possible to get a bad wheel bearing right outta the box

I just talked to my mechanic buddy who coincidentally owns a Ford Edge. He just replaced the wheel bearings too.

He said if the end nut is not torqued to 285 ft.lbs. it can cause premature wear. Too much or not enough torque is bad.

He said the other possibility is the CV bearings. He said they don't always make the popping sounds.

It's for sure the wheel bearings. We just replaced them and there was no difference.

Not sure how you go about checking the torque converter???

That definitely sounds like a wheel bearing and exactly the way a wheel bearings act when you turn.

Check to see if the tires are choppy on the inside or outside edge. Rotate the front tires to the back and take it for a drive and see if the noise moves to the rear. Ive seen many times where you think it’s a wheel bearing but is the tires making the noise.

Check the rear wheel bearings. Jack it up, put it in drive, have a helper spin it up to 25-30mph, climb underneath with a stethoscope and listen to each side. Sometimes noises transfer and things in the rear can sound like the front, and vice versa. They usually don't have play in them, they're just noisy.

The rear wheel bearing are a big pain in the butt. Ford puts some sort of locking compound on them to essentially glue them in. Once they're unbolted, heat up the knuckle where it won't damage anything with a torch, and wail on it with a sledgehammer, it'll move eventually. There's a special tool made for removing them, we had one at the shop but I could never get it to work properly, it would always (This word is unacceptable on Trapperman) sideways because the bearings were just too stuck.
