AC compressor makes a loud growling noise and lugs the engine briefly when engaged at idle and the truck has been sitting for weeks. After that initial grind, it works perfectly and makes no harsh noises. Can I replace the compressor bearing or should I swap out the entire compressor?
View 2 RepliesI have a 2003 F250 6.0l 4x4 with 230k miles. All of a sudden it seems that the fan is very very loud and there may be a very little lost of power. Also i just replaced the fan clutch not sure if that may have anything to do with it. What could it be. I need to get this fixed this week...
View 14 RepliesWe have a 2010 Hyundai Accent, with low miles (10,000), and the A/C Compressor is making a "growling" noise. The only way to explain the noise is when you hear a human try to immiate the sound of a dog growling. That's exactly what it sounds like.
First thing in the morning it doesn't make the noise to much, but as you drive for a bit you will start to hear it. Sometimes it's really loud, sometimes quieter. When you shut the A/C off, it will continue for a few seconds then stop.
The service department told me it was the compressor and it is, "pretty normal on the cars." How is that normal though? It sounds awful.
Every time my air compressor would shut off I got a loud annoying pop through the radio. Even if the radio was off I would still get the pop. I knew it couldn't be good for all the electronics in the truck so I tried a mod.
Diodes across the relay signal terminals need to be installed in performance carts to protect the electronics. I put one of these diodes on my truck this week. 100% of the pop is gone.
I used this one : ACC-KIT-CSD-1
Ok, so I have a Viair onboard compressor supplying air to airbags, train horn and fitting in the rear. With all that, I have multiple connections and some leak ever so slightly making the compressor cycle ever few hours. Question: Is there some sealant I can use with push on fittings and connectors to eliminate the leaks?
View 9 RepliesMy power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.
View 4 RepliesSo 2 weeks ago I noticed that after 30 minutes of driving on the highway my steering wheel started making a loud growling noise and vibrating really hard! When I hit the brakes it got worse but got better as I slowed to 30 mph. It doesn't happen all the time and not right away, only after a while of driving and the dealership says without codes they can do nothing...
View 7 RepliesRecently my 2000 F350 7.3 crew cab has been making a growling/vibration sound by the glove box at idle. Seems to disappear at speed/higher RPM.
Any thoughts on what might be loose at firewall passenger side area?
I think my pcm has gone bad. My wait to start light won't come on an when I turn my key on I can't hear my fuel pump cut on anymore. My vacuum pump is also making a loud noise.
View 10 RepliesI have a 2003 ford ranger xlt 4.0L and here recently my ac compressor has been making a loud click noise engaging even though i am not using heat or AC, so when it engages the rpms drop and almost wants to stall and it does this in about 10-15 sec. intervals, but when I am driving it acts fine. What is going on here, I recently had a vacuum leak and i found it and fixed it, and now this issue just started.
View 2 RepliesWheel bearing go out? My left front just starting making noise and when turned by hand you can hear the bearings are shot. Called around this morning and with my luck its on back order and the entire hub has to be replaced since the bearing is built into the hub.
Anyways, I was wondering replacing this unit themselves and how long it took to complete? I was going to let Ford do the work but I figured I have never done a job like this and wanted to give it a try and looking at some Youtube videos on older vehicles it did not look that difficult.
If I find that its not difficult I will tackle the other side as well since I figure it is probably not long before that side is gone also and I would not want that to fail while I am out towing somewhere.
a few times when making a tight turn on hilly terrain or a hill on a road, I've noticed a grinding sound in the front of the truck and a vibration in the steering wheel. I've so far chalked this up to the hill assist feature, but today I was on relatively flat ground in a parking lot with a dip in it. While crossing the dip in a tight turn, I noticed the same thing again.
I've checked the tires/wheel wells and there is no rubbing, etc.
My buddy has a 2011 250 and is having some weird issues with a clicking noise. It started out when you put the truck in gear (D or R) and touch the gas it would click. Seems to be coming from the middle to rear part of the truck. Now it clicks when he's driving. This all started after he got 35's and a leveling kit. It's taller springs in the front and added a block in the rear. It has less than 15k on it.
View 14 RepliesI posted a few threads about the P04DB code over the past several months. Last month while on vacation it came back and this time I was getting an engine light. So I finally got around to taking it in. The A/C blower was also making a clicking noise so I thought I would take care of both of those. At 41k and 42 months in service, the factory drive train warranty covered the CCV sensor replacement. The fan blower had to be replaced. So if getting that P04DB past 3/36, it is covered under the 5/60.
View 2 RepliesI've got a noise that I just can't find. Have replaced a bunch of stuff trying to eliminate this sound.. steering pump, both front wheel bearings, new pads up front, both caliper brackets and pins. Did a new turbo, verified the new pump is not air bound, brakes work, no noise with wheels up, lock to lock, pumping brakes the whole time.
Sound is prominent at 1400 RPM, does go up with RPM, seems sometimes to follow a steer to the right. When I shut down, not at full temp a clunk happens, like a mechanical stop. That clunk is less noticed once up to temp and it really started after the steering pump. Sparky came over, listened with a probe, says it's not the pump, my BIL and a close friend say the same thing.
Today, when I nailed it, rpm came on hard, tires smoked and when I let off quick, truck died, like something held the belt. It just slowed and died, restarted immediately.
Shawn listened to the transmission, says he heard nothing there either but did hear something above that near the back of the motor.
IPR is spot on 21.8%, ICPV is .80-.82 and [email protected] However, it has been dropping to lower numbers recently, saw 15.4% and it often sits near 19.4%-20.4% for periods of time. Tap the throttle, right back to 21.8%.
I'm at a loss. I've tested everything I can think of. I can power brake the truck, no trans slippage, it spins the tires easily around 10lbs boost. The A/C seems low on the charge, it is freezing the dehydrator and I added some freon, 18oz can, the clutch is not frozen. Turn it off, compressor stops spinning like it's supposed to. The tensioners are not frozen or squealing, water pump is not making noise, temp is 200 on the dot. Trans is full, no burned smell. Motor oil is fresh, filters clean.
It sounds like a grinding noise and I'm about to tear the cover off the HPOP. I'm at 150k now and know it will need replaced soon, I've spent $2500 in the last 2 weeks, but before I tear it apart......
One of the many things that impresses me about the 6.7 is how well it lugs...... it'll run right down to near 1,000 rpm in 6th gear and stay there till it absolutely has to shift. Like a diesel should. Well, recently, and now more frequently my truck is making some strange noises when it lugs down. It'll mainly do it if I'm towing light, like my flat trailer empty, or maybe if I have a decent load in the bed. But occasionally it'll do it empty. As soon as it lugs down low to 1,000-1,200 and pulls there for a few seconds you'll hear a couple squeaks, then a kinda chugchugchugchug noise. It immediately quits if you let off or make it shift down. It sounds like a turbo-related noise, but I don't really know. Truck only has 9k miles on it. I just know this is one of those things I'll take it back to the dealer and they'll give me the ol "we can't duplicate the problem here." What it could be?
View 8 RepliesI drive a '99 F150 4x4 5.4 EFI 196,000 miles. Recently I started noticing a growling noise that followed engine speed. I immediately thought alternator going out. So I pulled the belt off and it spins free and doesn't feel rough at all.
So I started it up and realized the noise got a lot louder when the ac clutch cycled. Now I'm thinking ac compressor. A short trip to my mechanic who didn't even really look at it very long and he said the compressor is about ready to seize up. I thought I might just put on an ac bypass pulley to get by for a while. Not really a sound decision in the middle of July, I'm thinking, but I'm poor and it beats having the compressor lock up, right?
Today, when I get off work and pop the hood with the ac off and the clutch not engaged the noise is worse than ever. I put a stethoscope (long screwdriver, I told you I was poor) on the alternator and it is making all of the noise. Turned the ac on again and it was really making noise now. So I applied the stetho-driver to the ac compressor and it is quiet as can be.
I am cautiously optimistic that the alternator is the sole culprit and that it only gets louder when the ac cycles because of the extra drag on the belt.
Does that seem like a logical explanation? Should I just try the alternator? I really don't want to destroy a perfectly functioning ac system only to find out that it was OK to begin with and I don't want to buy a $150 alternator for no reason either.
I have a 2003 6.0l... When I first bought truck, seemed to run fine. Since then truck has broke down on me once. I took it on a six hour drive, and couldn't turn vehicle off, because if so, truck wouldn't start back up until cool. After getting to my destination, fans seemed very loud every time I pressed pedal, and seemed very sluggish. Drove it a couple days and boost was low and fans continued to sound like they werre engaging even when I first started truck for the day. Had truck towed to shop, because it cut off on me when driving.
At shop : Truck had air filter, water in fuel sensor, o-ring for draining plug, new ICP sensor and harness, and HFCM cleaned up as it was filled with gunk.
After shop : Fans quit being so loud, but have not had near the boost I had before issues started. Truck struggles to go from stop, and around 15 psi boost gauge starts shaking erratically. Also, I have been losing coolant in a short period of time, and can't see any leak coming from anywhere, and also my radiator has been making a sloshing/gurgling noise and it will stop, then come back all within bout ten seconds. And I guess while I'm writing, I should mention the bucking after it downshifts in about third or fourth gear giving it gas makes the truck buck until the RPMs are above 2000 or it upshifts or downshifts, and at an idle seems to miss until warm.
2005 ford f250 6.0 Started making this noise from front about a month ago, can't figure out what it is. Only happens when letting off accelerator or changing from P - D. The truck acts normal, seems to be louder when the truck is warm.

The code was P040 which said is for the EGR system so I removed the EGR valve. It was completely plugged in the top section. I cleaned it out and cleaned out the ends of the EGR coolers then vacuumed the port out and reinstalled the valve and removed battery cables for 2 minutes to remove old check engine light codes . I drove it for 50 miles and it runs fine now and the check engine light did not come on. It still has a loud ticking noise behind the glove box which I read can be the blend door relay so I will try to pinpoint exactly what is making the noise as soon as I figure out how to get the glove box door off.
View 11 RepliesHow do you diagnose a bad fan clutch? When driving in tow/haul mode I get a noise like a jet engine. It starts going down grade or upgrade and does not stop after leveling out. I have switched off tow/haul and it is still there. Over on the Diesel Stop site I found a couple of guys who have had the same problem. Concern is everything I have read there are no codes thrown. Have not taken to my local Ford Dealer to see what they say.
