Ford F-150 (2004-2008) :: Loud Rear End Howl / Whine
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.
Golf V R32 :: Electronic Whine Sound Under Back Seat When Slowed Down
2008 r32. First time i opened it up on the highway, noticed a weird electronic whine under the back seat as soon as we slowed down that wont go away. It changes pitch when you shift and sounds like a weird electronic sys trying to mimic an exhaust leak. Id think fuel pump, but seems louder on the left side (fuel flap on right). Since i talked her into it and i apparently caused this noise, shes gonna kick my ass if I don't fix it. Its somewhat warrantied, so toss out whatever, I am not scared to go to the dealer with 500 things i want them to look at, but i need to know if their diagnosis is correct or total crap. Ive never dealt w 4motion (its incredible) and my newest dub is also a vr6, but its a 92.

I was driving my 2008 Prius and it abruptly slowed down and became undriveable. I had all of the warning lights - the red triangle master warning light, hybrid syatem warning light, and the check engine warning light. The car had to be towed home. The gas engine starts and runs - driving forward feels like the brakes are on - will not drive in reverse,. I checked the codes and had the following : POA1D, POA78, POA90, and POA94.

The wife came home with a really loud screaming noise coming out from under the hood. I used my stethoscope and I'm 95% sure it's the alternator. It was a pretty easy removal process, sending it out to be rebuilt tomorrow. I guess at 90k I have no reason to complain.
I chose to get it rebuilt because of info that I had heard true or not, that Toyota alternators have an internal clutch and aftermarkets may not work properly.
Ford F-150 (2004-2008) :: 2007 Cab Corner Is Bubbling / Metal Is Exposed
My 07 Lariat cab corner is bubbling. I really think this is a paint adhering defect as there was no rust underneath, just bare metal. It has now started to rust where the the metal is exposed. How to tackle this? I was contemplating paint matched linex all the way around the bottom, or taking to a body shop which would be expensive.

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.
Ford F-150 (2004-2008) :: Back Up Sensor Whine

View 1 RepliesPrius (2004-09) :: Super Loud Whine From Engine Bay For About 10 Minutes
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.
Ford F-150 (2004-2008) :: Whine Coming From Rear Differential
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.

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.

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..
View 6 RepliesSanta FE SM (2001-06) :: 2004 - Passenger Side Low Buzz / Whine - Loud When AC Or Heat Defroster On
I have the 3.5 LX AWD 2004 Santa Fe 102,000 miles purchased new. My power steering fluid reservoir was leaking from the top a lot. I read here that the screen in it could be clogged. I went to the garage the manager never heard of such a thing he said, and never heard of a PS reservoir having a screen (I gave him the TS. He said if I got the part and wanted it changed they would change it. I did that. It was done 2 weeks ago and now it all dry under there. But, now.. there is a low whine on the passenger side under the hood toward the back, but when I put the A/C on or the heater on defrost (Not when heater is on, only in defrost) there is a loud rumble/hum from the same area. Shut A/C or defroster it goes back to a low buzz/hum again.
I had the power steering pump replaced at the dealer about 2 years ago, its not old. The noise is NOT any louder when I crank the steering wheel all the way to either side. The fluid since replacing the Power steering fluid reservoir is staying at the same level, full, no leaking. When I put everything on, lights heat only (No defroster), radio, lights the noise doesn't get any louder either, I tested that. The other night after driving about a half hour to and from a place I went to u-turn in a parking lot and that whine was louder for a minute and while driving forward slowly out of the parking lot getting up to speed.
When I asked about the PS fluid reservoir, I had also, asked the repair shop manager his opinion, of that loud hum/rumble when I put the A/C on (At the time I thought it only happened with the A/C when the compress popped on). He listened said "That's the A/C compressor it's going and its going and cost more to replace it then its worth on your 2004." So, that's the background.
Questions: 1. Just wondering if you think it is the A/C compressor that is the loud noise when on, would the A/C compressor even go on when the defroster is on, the A/C is off, and the heat on and there for still make that loud rumble??? Or does that defroster fact kind of mean its not the A/C compressor??
2. What is your opinion of the low buzz/whine noise now (When heat/AC off)? I can't pin point it totally in park when listening, its very low (Except that one point where it was loud for a few minutes driving out of the parking lot.) (The motor sounds a bit louder in it in front too just side observation)
I almost worried if the low buzz was the Transmission as its fluid hasn't been changed in a few years (Because the mechanic said sometimes changing the fluid when its been a lot of miles between can actually cause problems to the transmission) It was done at the dealer around 45,000 miles and now my Santa Fe has 102,000 miles.
Could the power steering pump be going bad in only 2 years from what I've described? Or could the PS fluid reservoir having been spitting PS fluid from the top for a couple of weeks have caused damage to the PS pump now?
The fluid never got lower then full when it was coming out of the top and only when driving, I kept checking it. The mechanic who put the PS fluid reservoir in said he had no idea if it leaked from the top due to the screen as he felt the screen had only minor debris that was not blocking a lot of the screen since its a big screen (He didn't look too hard though), and it was possible even a small crack in the reservoir could cause that same fluid coming out at the top. He said it could be either he didn't notice a crack either.
Or are these two noises possibly not related even though possibly from the same area on the passenger side under hood.
Subaru - Forester :: Transmission Stutter When Slowed Down To About 10mph To Turn And Started To Accelerate
When my 06 Forester was still under warrantee I brought it to the dealer to diagnose a "stutter" in the transmission after I had slowed down to about 10mph to turn onto a street and started to accelerate. They could not find anything wrong and so I have lived with it until recently when I decided to try the local tranny shop that has a good reputation. They could not find any problem although at first they thought it might be engine related (mass air flow sensor), but that was ok.
