Ford A/C :: Terrible Squealing Noise With Smoke
May 3, 2010
2 days ago, I was running my truck, and started the A/C. abut 3 mins into letting it run, it starting making this terrible squealing noise, with smoke and then it quit when I shut the A/C back off. The one side of the A/C line was SUPER HOT to the touch(on the driver side near the top of the radiator).
After doing some much needed research here on FTE, I did what was suggested and check the Air gap. it's about .026 give or take some. I pulled the faceplate of the clutch and there is no shim's behind the faceplate. The clutch moves when the A/C is off and also when the truck isn't running. Not completely freely, but not seized either.
Is this going to involve a new compressor and complete discharge? The only thing I could find that even closely resembled a washer was a snap ring inside the compressor housing. The faceplate with the spring load shows some metal to metal wear. I'm no einstein when it comes to A/C on auto's, but my bet is is on a new compressor..

I turned on my AC in my 94 ford f250 and it made a squealing noise then I started to smell smoke or more like electrical burning. I turned off the AC and the squealing and burning stopped. I found that the compressor was the problem and after pulling the pulley and clutch assembly off I found that the coil had melted or got really really hot and smelled lie it had burned. My pulley and surpentine belt were still spinning fine so what happened? My AC had worked fine a few weeks before this.

I have a 2002 F-150 and started making terrible noise when turned on heat/ac. The fan cage was full of acorns and pieces of insulation in it. How can the squirrels get in there? I have looked and see no entrance, maybe just don't know where to look.

I have a 2001 F250 Super Duty 4x4 with the 5.4L I bought it cheap and runs well. While going through doing the stuff that needs attention I noticed the 4x4 isn't workijg. It has whatbappears to be some cheap maybe plastic locking hubs and the manual pull stick onj the floor for engaging the 4x4.I can pull it into 4H and 4L, the dash lights confirming come on but the front wheels will not lock in.
One of the cheapo hubs looks like someone clamped vice grips on it to try and turn the and doesnt seem to totally lock in. The drivers side hub sounds like it is lock in but makes a terrible lound clicking noise.
They may be the stock hubs, have no markings to designate the direction to lock and unlock and do appear to be somt sort of plastic hub.... Are the hubs my problem since I can manually pull it into 4x4 and I can see the 4x4 shaft spin but the tires are not engaging?

I have a E99 F350 7.3L 4x4 I know some or most of you have already probably replaced this part and or pulled a front axle shaft out. So here is my question...In the pictures provided you can see what I think everyone is calling a "Dust Seal" and as you can see it is bad and making a very terrible noise when i hit a bump...I was wondering what parts I would need to replace this seal? I tried looking it up and just get lost in all of the other things....I have found write-ups for the axle being removed while changing ball joints but none by it self to just replace this seal.

Within the last few weeks my Sienna has begun making a terrible noise and shudder when I accelerate. It seems like it is worse on the front passenger side. When slowly accelerating from a stop it makes a hollow pitched metal scraping sound that increases frequency with speed (up to 25-30mph) and at higher speeds just the shudder, no sound. Initially this was intermittent but now it is an all the time thing.
The sound and shudder only happens when accelerating, regardless of speed. When you are at cruising speed on the highway there's no shudder as long as you are at constant speed and at any time if you take your foot off of the gas pedal the noise and shudder stop. Because of the link to acceleration I don't think its a wheel bearing.

I have a 2010 Sonata V6 that I bought new. It has a little less than 50K on it. I tried to start it today and it made a terrible noise then died seconds later. I popped the hood and then started it again and the engine was shaking violently in the engine compartment and making a terrible knocking noise. I had driven it 12 hours earlier and it ran fine. I called a tow truck and had it taken to the dealer but if I know my dealer, since it is Sunday they probably wont get to it until Tuesday. Also, this car has had the signature V6 valve cover leak that has been fixed 3 times. I noticed it was leaking again about a month ago and I have just been checking the oil and adding it as it needs it. I dont think the engine ran out of oil because I checked it before the tow truck came and it was between low and full.

I have a 2004 Ford Escape Limited. There is a squealing noise when I accelerate from a complete stop. It's not there constantly, and seems to have started when I started using the AC. When I had my oil changed tonight at a Tires Plus, I asked them to listen, and the mechanic thought it was a valve related issue since it's not a constant noise. He only got it to squeal by hitting the gas really hard. He said to take it to a dealer...which is super expensive!

I have a 1997 f150 with the 4.6l triton that just started to make a squealing noise. I have replaced a couple of pulleys that were bad but that did not get rid of the problem. It only makes the noise when I give it some gas and it is coming from around the fan clutch area.

Just noticed a loud squealing sound coming from the engine area before I start the truck, but with the key in the on position. I'll try to get a video the next time it happens. I assume it's something starting/warming up, but it's louder than anything I've ever noticed. It lasts probably 20 seconds.

I've had this truck almost 2 yrs now. It is not a 4 x 4. The trouble I am having is on the driver side. What happened first was while I was driving it i heard a loud squealing noise then a loud pop. After that the truck seemed fine I checked under it and everything looked ok. After that I drove it to a couple stores did fine but i heard the loud pop again. Once I left the store I was driving on the highway and it jerked to the left and i heard a grinding/rattling noise. I put my flashers on slowed down and every once in a while it would still pull to the right but the grinding noise remained constant. I parked it waited for a tow and i turned the truck around and drove it up the ramp there was another pop sound but I didn't hear the grinding. It seems to happen on and off. And it doesn't matter if I am turning or going straight.

This squeaking/squealing noise only happens when letting off the gas after accelerating 70%+ throttle. Quickly letting off the gas after revving up makes the noise . It sounds like it comes from under the drivers side door, and does NOT sound like a turbo. Its a creaky/squeaking noise.
Wont happen in park, does happen in 2wd or 4wd, on highway or in city. [URL] ....

Over the last few days my f150 has developed a really annoying squeal that's intermittent. I can never really predict when Ill hear it. Usually I first hear it when I am accelerating to a speed greater than 30 or 40 mph. And it will continue if i keep my foot on the gas or if i slowly hit the brakes. Usually the only way it will stop is if I slow down to under roughly 30 or if i hit the brakes. pretty hard.
But sometimes Ill hear it at various speeds just for a second or two, usually when I am turning or when I am decelerating by taking my foot off the gas and not braking. again its hard to predict. It sounds really similar to a car with squeaky brakes. and just like squeaky brakes, you can hear the noise slow down as the f150 slows down. but again it doesnt only happen when i hit the brakes. I dont know what it is.

Purchased new 2016 450 platinum. Has less than 800 miles on it and has a terrible vibration between 70-80 mph... Already have taken to dealer who stated there was a wheel out of balance and that they fixed the issue. But still present.

Why I am getting such terrible gas mileage? The truck refuses to move off of 12 mpg. I made a 500 mile trip half of it at 70 mph running 2100 rpm. And when I filled up I calculated out 11.3 mpg. After that fill up hopped on the interstate and was running around 85 @ 2600 rpm expecting my mileage to drop even lower. Then i was on two lane hwy again constantly passing people and it only dropped to 11.1 mpg. Now no matter how easy I drive or how hard I drive it will not move over 12 mpg. Whether the tank is 100% hwy or 50/50. Its a 5 spd manual 4x4 with no modifications running the 4.6 v8. I just swapped air filters to a K&N and still no change.

Just recently when pressing gas pedal heavily, my truck makes a squealing noise. What that is?

I am now getting a random 'whirring' or 'squealing' noise from the front. When it starts, I feel some vibration in the steering wheel and floorboard and for sure can hear it. Starts on it own at random, sometimes when I hit a bump in the road. Stops at random, sometimes when hitting a bump in the road. Lasts for different lengths of time. Always stops when coming to a stop at about ~15 mph. Seems to change pitch ever so slightly if turning when it is 'whirring' or 'squealing'.

I purchased a 2016 f350 XLT 6.7 it's basically two weeks old with roughly 1500 the horsepower and fuel economy is incredible however it's developed a terrible shake during regen. It occurs every time regen and shifting down isn't working. Hard to believe a two week old truck has to go back to the dealer and from what I'm reading it sounds like they're not solving it.

I have a 2005 5.4 F-150. First off it came to me on a rollback because the owner tried to replace his plugs after he noticed it missing and of course broke one off. So after I extracted the plug from #8 cylinder and installed a new plug I cranked the truck and it was idling very rough and had a terrible miss around 1200rpm. I pulled the codes and got several misfire codes and ignition coil faults on #5,6 and 7 cylinder. Popped in 3 known good coils in these 3 cylinders with no difference.
On Mode 6 on my diagnostic software you could watch the misfire count steadily increase on #7 and every now and then there would be a single misfire on #5 and 6. It also had several codes for O2 sensors biased, stuck rich on that bank. Well since it had a brand new plug and coil, I popped an injector in #7 and havent had a single misfire on it since and it also started idling alot better and all the O2 codes went away. The problem I am having now is #5, 6 and now 8 will randomly misfire, sometimes build up a steady count on one of them, sometimes just skip around between them.
The truck has brand new plugs in all 8 and new coils on this bank also. The truck has 115,000 on it and does have some cam phaser noise on the bank causing the problem, but its not too terribly bad, I have heard alot worse. My problem is something on that bank only as the passenger side bank is fine. I am wanting to say cam phaser now since this is the side with the noise. I have changed them before but have just experienced the noise, never one running like this because of it. Possibly jumped time a little?

I have a 2002 SuperCrew 4x4 that makes a squealing sound that starts at 3000 rpm and slowly goes away as it approaches 4000 rpm. It does this when you are in park or in gear. I believe the torque converter is going bad, but just want to make sure before I tear it all down.
