Ford F-150 (2004-2008) :: Battery Light On And Whining Noise From Pulleys
Feb 4, 2016
I have 2005 F150 XLT 5.4 litre engine and my battery light comes on after letting the truck run on idle or sometimes driving.
Last Saturday went out drove it heater on and radio on I smelled something coming from the heater kinda like burning wire smell didn't think anything of it no smoke from heater (indicating the core was bad) no lights on the cluster nothing; went into the bank let it run came back out my battery light on. Drove it home and while driving the light goes off.
Opened the hood and the smell was coming from the alternator. So I turned the truck off. Let it sit for an hour or so then I took my voltmeter to see if the battery was good. The battery was 12.4v with engine off. Checked my battery connection for corrosion or loose connections everything was tight there was some dust on the battery terminals so I brushed them off. I checked the battery cable that goes from positive to the alternator where it connects to the alternator with that nut it was good, clean and tight.
So I started the engine up and I can hear a whining noise from one of the pulleys. Let it idle for 2 minutes no battery light so I put my voltmeter on the battery it read 13.8v, so I turned on the A/C, head lights, radio and the heater tried again the voltage dropped down to 11.9v then the battery light came back on. Also through all this my battery gauge in the cluster always stays a half way mark doesn't drop or go high. Next with the engine turned off I took the belt off checked the pulleys the idler pulleys seem fine and the belt doesn't show any glazing but the alternator was hot almost like touching a hot exhaust manifold.
So for the last 3 days I have been trying to come up with how to resolve this issue obviously it could be the alternator going bad but the battery has never lost a charge yet I let the truck sit for these past 3 days and today I started the truck and it started right up I don't see any dimming lights except it has a whining noise and the battery light didn't come on immediately I let it run for 5-10 minutes before it came on; I even drove it around the block and the whining noise gets louder every time I step on the gas. To me it's either I need new alternator, tension pulley is bad or the idler pulleys are bad but they turn fine.

So about 3 or so weeks ago I brought my 2006 GX470 into the Lexus stealership and had the pulley's, water pump, and timing belt replaced. Fast forward to this morning, about 300 miles driven and it suddenly when started today has a terrible whining sound and the battery light is on the dash.
I need to go over the invoice from what they did but I believe it was 4 different pulley's they wanted to replace. Not sure if it was anything on the accessory belt path, but I imagine if I call they will blame the alternator and tell me to shell out hundreds more?
I didn't run it long like that, only a minute or so. Popped the hood and I could smell the burning rubber smell so I quickly shut it off. Nothing *appeared* seized to me however.

Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.

I've been noticing more and more lately that while my trucks in 1st or maybe 2nd gear, say, slowly coasting around a parking lot for example, there's a whining noise coming from either the rearend or the tranny (cant tell which). It gets louder and more high pitched as I move faster then disappears as soon as the truck shifts gears..
Is this something serious like my transmission on its way out? From what I gather a lot of people seem to have a similar thing going on.. From what I can remember my truck has done this since I bought it, but lately (and maybe its just me) I seem to notice it more like maybe its getting louder..

I noticed my engine whine more than it usual since the last few days. So, I took it to the dealership and have them check. They said that it is the idler pulley going bad. Just want to see some info on diagnosis.

'05 F150 5.4 Sounds like a whining noise from the front end when turning to the right or going straight. Goes away on left turns. Thought it was tire whine but put originals back on and got same thing. 13.5x35 verses 275 Truck has a Fabtech 6" lift. Right CV axle seems tight, rotor assembly replace 2k miles ago. Any other option before going into front diff?

I just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.

2008 GX with 42K and just driving home and battery light comes on and a whirring noise--pull over and open hood smell strong electrical smell--ok Alternator fried. Got it home and battery light off but still when I put a meter to my battery with engine running its only putting out 13.4V? should be at least 14.5-6 correct. Has to be Alternator cause of the symptoms and the burning electrical smell..
SO WHO has changed alternator and how hard was it? Im looking for it and I think its under the Power steering pump it seems left side engine looking at it.??

I'm new here to the F-150's forum although I've owned a few since 2001. I bought this F-150 '05 5.4L Lariat. Really nice truck. But when I purchased it, it had this weird noise inside the cabin. I thought because it had a camper on it that some tranny noise was coming up thru the camper and the rear cab. After taking camper off, the noise was still there. From everything I've read online, it could be rear pinion seal, differential bearing, tranny, front hubs, etc. I have left a video. Pay close attention to the little whine. Kinda hard to hear if your not listening for it.
Note- when i drive it is most definitely coming from the middle to rear of the truck. But I'm not ruling out anything. I have looked underneath the truck and the differential is dry and the driveshaft area near diff is dry. No leaks. I have not checked fluid in diff. Is there an easy way for these trucks? I have read and heard about adding an additive? The noise starts at about 10-15 mph all the way up to 80. I've never taken it past 80 but I'm sure it's still there.

My 2007,4.6 is making a whinning noise from the front of the engine around the idler/tensioner/alternator. What I have read it might be a problem with the alternator getting cold, I forgot to mention it's cold up here. Fixed by changing the alternator and did the noise come back as it seems to be a design problem?

I just bought a 2005 fx4 and there is a whining or whirring sound coming from the rear of the truck when I hit around 70km/h. the second i let go of the accelerator it stops.
Today when I got home after a 15 minute highway drive, i got under the truck and felt the differential area. it was warm but not hot. and there was a wet spot on it. i wiped off a drop of oil. there was also a wet spot on the bottom, seemed to be just water? I'm not sure.

Some family members borrowed my truck, and when they returned I have a loud whining noise coming from the rear axle, which I have determined is a 9.75 rear. I checked oil level and it was high enough, but has a slight leak from the pinion seal. Everything feels solid but I have nothing to compare it to.
Its on a 2005 Super Cab with the 5.4L 183,000 miles. The front pinion seal was replaced in Feb 2 years ago, by the dealer's mechanic, who may have been a shade tree mechanic.
I am a Youtube Certified Mechanic, as in, I watched about 10 videos of people working on their 9.75 differentials, and realize I don't have all of the tools to do the job, such as a press, or race drivers, or the special gauge.
How many of you have tackled this issue? What did you find? What am I looking at for cost? I am on a very small budget.

Purchased a 2004 Lincoln Aviator, AWD, 200k miles at an auction, I'm familiar with standard 4wd systems, but this auto AWD is confusing me.
Truck is auto engaging the AWD after 30 seconds of driving, if I reset it back to auto, it locks AWD 30 seconds later.
If I'm driving above 30-40 MPH this gives a pretty intense whining sound. I assume overheating the system. Last test drive put it in AWD disabled mode- I assume from overheating.
Truck wants to auto lock AWD no matter what, I don't seem to be able to do anything to prevent this other than turn OFF traction control- which then ends up disabling the auto AWD and telling me to see owners manual as well.
Truck does pull a little from needing ball joints, but would this tell the computer to engage the AWD constantly ? Any thoughts?
I'd also mention the ABS light is on- I'm guessing a speed sensor could throw this off as well? My code reader can't seem to connect to this aviator- it could connect to my old explorers, but not the aviator strangely enough.]

I posted awhile back about a loss of power and hard shifting in the transmission. I thought I had it fixed, well I kind of did...... Replaced the IWE that had locked in solid. I replaced both, added some transmission fluid, new front brakes, and a new belt back in July/August. Truck was fine for a few thousand......
Well it's back. Now I have a noticeable whine in the cab. I haven't pin pointed it yet. It is only audible when the truck is running from 35-50 mph. It is not RPM dependent, it doesn't change when I take it in or out of four wheel drive. It isn't there when the truck isn't moving.
The truck has 61,000 on it. I bought it with 35,000 on it because I wanted a vehicle that wouldn't nickel and dime me. Something I could climb in and not worry about making home.
Well here I am less than 30,000 miles later and I have had issues with the fuel controller under the bed, brake calipers sticking, IWE's, new shocks, broken front coil spring, recall for the airbag, tie rods, ball joints, power window regulator, and now what appears to be a transmission.
I come from a long line of "FORD" guys, but I am seriously considering something else. This 04-08 model has to be one of the worst pickups ever built by ford.
Are the newer ones any better? Other than routine maintenance a vehicle shouldn't have to be touched before 61,000.

About 45 seconds after start up Battery light on dash illuminates. Gauge shows in good range. Fluke meter across battery terminals reads 14.2 - 14.4 volts at idle with lights on high beam. No TDC's.
Truck is new to me, engine was replaced recently so I did do a check of harness connections with no problems found, what I should check next ?

Last night battery light came on. Drove 40 miles home with lights on. Today, it started so I headed out. About 10 miles of battery light on, gauge fluctuating mildly either side of middle, gauge suddenly drops dramatically. I turn around and head back. After a mile or so there's a terrible growling under the hood, sounded like it could be an alternator bearing. Just as I pull over, the noise stops but entire dash goes black. Popped hood, alternator spinning quietly and not hot. I drove back and it started stumbling and surging as the battery died and it finally quit almost all the way back.
I have battery on charger now. I assume the BCM is the regulator by feeding current back to the field? If so could the growling be the BCM feeding back a huge field and the rectifier bridge growing? And the BCM fuse blew because too much current to alternator field coils? Will it start with a charged battery with the BCM dead? I need it to run to get to the parts place. Which fuses do I need to check? Then, how do I check the alternator, wiring, BCM regulator to find original problem?

my truck has been acting kind of funny for the past 2 days. my RPM's are not as high as they usuaully are and my battery volt is 14.2 watts and when i hit the brakes and turn it drops down to 12.5. when that happens my battery light turns on, steering wheel tightens up and truck slows down. the only way to get my truck running after that is turning it off and starting it up again. What might be wrong or had the same problems?

This is concerning my little brothers truck. It is a 2008 4.2 liter with around 55,000 miles on it.
He drove it to work today, and called me this afternoon saying that the truck starts then dies a few seconds later, and the battery light illuminates. He and a coworker checked the battery and connections....cleaned off corrosion on terminals, battery reads 12.xx volts without a load on it, it is the original though.
As of right now he is changing the fuel filter which hasn't been done yet. I also know of issues with the fuel pump driver module. I remember checking the one on my 2005 back when I owned it. As I recall it causes a no start condition, but would it cause a start then stop condition like this? He will check this when he is done with the filter.
Anything else that we can check in a parking lot to try and at least get it home?

I recently had my alternator and battery replaced due to my truck dying out randomly on me, tested the alternator and failed, replaced battery, and still got the same results, battery gauge seems to drop quickly, what could be going on, I have been told to replace the fusible link that goes from the battery to the alternator....
