Ford F-150 (2004-2008) :: Loud Rear End Howl / Whine
Jan 21, 2017
My '04 4wd has a pretty loud rear end howl, it is a LS but don't think it's an LS problem, no noises or chattering when turning. Howling is loudest at 50 to 60, but some noise at all speeds. I don't mind tearing into the rear myself, but not sure if I could tell what was wrong just by looking, i suppose bad bearing might be obvious, but not sure how to diagnose gear lash tolerances. It only has 107000 mi. and is an 8.8 rear I believe.

i have an 04 f-150 with a 5.4 motor. about 2000 miles ago the power steering pump started to whine really loud. I sucked out the power steering fluid and started it up and the fluid that back into the tank looked like it was gritty and rusty. I replaced it out a few times and no change. I then did the job of replacing the power steering pump which was about a 5 hour job.
It was quiet for about 5 miles and the new one started whining. Every week I have been sucking out the old fluid and replacing it and it still seems to be gritty. What could I do to quiet it down? the steering works perfect btw. I am looking at selling this truck and buying an 09 or newer ford and want to quiet it down before selling it. The truck has 88,000 miles on it and i am the original owner.

Slowed down to turn a corner and the strangest, loudest, noise - a loud screaming whine that lastest like 5 seconds. Also perhaps a spin noise and a little bit of a thump like going back in gear. Went out to drive it again, and again it did it but only once. I then drove it hard, fast and slow, in 4 wheel drive, out of 4 wheel drive, stop and go and it has not done it again.

I got a new to me truck. It's a 2004 F150 Lariat 4x4 with the 5.4L. It's got a whine that I believe is coming from the rear differential. I'm going to change the fluid. My axle code is 26 which I believe is 3.73 non-limited slip. My owners manual says to use 75w-90 but I've seen a lot of posts on here that say to use 75w-140. Which is right or better? Also, is my rear differential the 9.75"?

had a leaking rear driveshaft seal at the axle and replaced it and fluid. 75W145 full synthetic as recommended. it was changed at 128000 and I've started to get an axle whine over 25 MPH up to 65-70MPH. quites down around 80 MPH. I just checked it after 2 months (whine just started) with 133000. Any TSB. does this fall under TSB 05-23-3? Noise sounds like I've got really aggressive tires on the truck. Only have Dayton HT all season. Did not add the XL3 additive. Would this work at this juncture.

Well i picked up a 96 4x4 with the 4.0 a few weeks ago and been fixing stuff weekly that i find wrong. One thing i noticed was the rear diff was leaky but couldn't get the fill plug out so left if for now. Last night my wife was on interstate and it just started making a loud noise so she pulls over calls me. I get there and drive it and it makes a woowoowoo noise and it got louder as speed increased. She was 3 miles from the exit so i drove it about 15-20 to get it off interstate than another 2 miles to her sisters. We let it sit for a few hours and found a flatbed to haul it home, and when we finally got home i drove it off the flat bed and now it was making a loud clunky noise. Parked it in drive till today. Cracked open the rear and no fluid came out.
Inspecting all the gears looked good no metal in bottom so i went and got a new rear cover and 3 qt. of fluid. Put it back together and the woowoowoo was still there but seemed to slowly go away as i drove it around the block. So what else could be going on here or do i need to drive it and warm up the fluid so it circulates? I also noticed a sheeee sound like metal on metal when braking but i changed all 4 rotors and both pads last week but i noticed the brakes in the rear that look like drum brakes was bare but i assume that is only for the ebrake so didn't bother changing them yet. Could those be hitting the inside of the rotor and making the metal to metal noise?

I have had an engine growl / howl problem that seemed to disappear with the cooler weather. However, turning the A/C back on yesterday, the growl/howl re-appeared. Is the A/C compressor bad? A/C clutch bad? Heading out on a long distance trip at the end of the month.
When the moan/ groan comes from the engine bay intake area, I have to back off of the throttle in order to re-accelerate... Gas pedal seems to become dead...

I drive a 2006 F-150. I'm new to the forum and already found some good info on the annoying tick coming from my 5.4.
I have recently purchased a ski boat and lately when towing my boat and coming to a stop I feel as light movement coming from the rear of the truck that feels like something slides forward slightly. When I accelerate "it" slides back and if I accelerate quickly, "it" makes a loud clank noise.
I have ruled out hitch, receiver, ball, anything from the boat/trailer etc... It is coming from the transfer case/ spare tire area under the truck and it only appears to do it (or to where it is noticeable) while towing the boat.

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.

I own a rear-wheel-drive 1999 Jeep Grand Cherokee. I recently had both rear axle seals and bearings replaced. At the same time I had the mechanic check U-joints, shocks, etc. The noise from the failing bearings is gone, but now I have a loud "howl" that gets louder the more I accelerate. If I take my foot off the accelerator, the sound is gone. As soon as I accelerate, the sound returns. It is barely noticeable at speeds less than 35 mph, but the howl gets increasingly louder as the speed increases.
I returned to the mechanic the same day I picked up the Jeep. We went on a road test and I was given a story about gears in the differential and that despite the noise everything was mechanically sound. Even though the sound was not present before the seals and bearings were replaced, the mechanic assured me that nothing is wrong. This howling is giving me a headache!

I have a 2004 Ford F250 Turbo Diesel, egr delete, headstuds, intake, dual stacks, etc and when i turn my wheel a loud whining noise comes from under the hood, I noticed it put tension in my brakes. When I accelerate it gets louder and when i let off the gas it goes away... i checked my fluid in my steering pump and it was low so i put some more in and the next day it was all sitting under neath the truck.... any quick fix or do i need to replace the whole pump?

I have a 2004 F-150 FX4 4x4 with 80k with a 9.75 LS, recently I've had the truck start making a humming sound/vibration (similar to the sound/feel you get when crossing onto rumble strips, only not as intense) when at speed anywhere above 20 mph or so, its doing this all of the time. The strange thing about the sound is that is only occurs when I am driving completely straight or to the left, if have the steering wheel just slightly turned to the right of center, the sound and vibration completely goes always until the wheel returns back to center. also I've started to notice that sometimes (not all the time) at lower speeds when let off of the gas and decelerate. I'm getting a very high pitch whine that sounds like a metal-metal sound but only lasts for a few seconds then goes away.
I cant tell where if the sounds are coming from the front or back and i cant decipher which side it is coming from. Also, I don't know if it is related but over the summer, probably june or so, i had to drain the fluid from the rear end and replace and add an extra bottle of friction modifier to get rid of the shuddering problem alot of people with 04's have run into.

It only does it sometimes. When I put truck in reverse the back up sensor sound just goes BEEP none stop even if there's behind my truck. Sensors on the bumper looked clean. Why?

Yesterday while on an 50 mile I had much more serious whine from the engine bay for about 10 minutes, that I think was from the serpentine belt. I wasn't driving, but my driver (my gf) called and I could certianly hear it on the phone. I could hear it in the cabin, then I could hear it from outside the car. She opened the hood and said it seemed to be coming from the passenger side down by the firewall, engine side. I could hear it while driving and while she was parked and idling.
I'm not familiar with the prius engine bay yet but that area is where the fan belt is i'm guessing if its like my other fwd cars.
It was cold out. She was driving about 55 mph. She had already driven 45 miles when it started. It continued to whine like that while parked and idling, and also while driving. She started and stopped the car and it would start when the car was started. I'm sure she had the heat on the whole time so i can't tell you if it quit when the engine cut out, but i bet it would have.
Then after about 10 minutes it stopped. It started a little bit at start up and then went away. She drove home 50 miles and didn't notice it anymore. I drove it last night in 12 degree city/suburban driving/ highway for 50 miles and never had it come back.

Noticed a small whine coming from the A/C compressor? I caught ear of it the other morning when I was putting the trash on the street and the truck was running. It's definitely the A/C because when you cut it off the noise goes away.

I own a 2007 GX470. It has suddenly developed a loud whine. We replaced the power steering fluid (which we were told was filthy) but the whine is still there. The mechanic has suggested we drive it for about 500 miles to see if the noise disappears. I'm not crazy about driving it with the loud noise but don't mind. He says the car is safe to drive.

I searched and found a couple of threads with regards to a vibration or howl at the rear of some of the V6 Touaregs. Starts around 55MPH and continues up to 70 (fast as I've gone since this started). Not so much a vibration as a low pitched, but loud, howl.
Wife and kids noticed it as well. First time, since its winter, I thought perhaps snow or ice in the wheel well or a buildup on the rim was causing an imbalance. Not the case.
Wheel bearing? Car goes in for service next week, but I have a feeling that if I can't get it narrowed down dealer will tell me everything is okay.

My truck has 57k miles on it. At 1800-2100 RPM it whines under or over it is just fine. it has a new air filter in it as well, still makes the noise, it doesn't matter what gear i am in, it only does this under load. if i free rev it , it will not do it.

We've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..

My truck seams to have developed a whine. It gets louder with increased RPM. Sounds like its coming from the motor, specifically the front of the motor, maybe one of the pulleys? Water pump??? Alternator??? Im not sure but Im about to head out on a 2800 mile round trip pulling a heavy load and want my truck to be ready for the trip...? It sounds like its gotten louder in the last couple weeks but I think its just because I had a new manifold installed on one side and the truck is quieter making this seam louder.... But I don't know if I should be worried about it.. I don't want to waste money (right before a big trip) chasing a noise if its not something that is an issue..
