Ford F-150 (2004-2008) :: Hum Almost Sounds Like Faint Grinding When Driving Along Flat Road
Sep 20, 2013
2005 f150 super cab, 5.4 liter, 4x4 107k miles. I have a 12 bolt rear differential and the tag on the door has an axle code of "B6". No noise under power or braking but if your driving along flat road and not much power is needed to keep the truck moving then there is a hum almost sounds like faint grinding but not quite. The differential housing gets hot to touch after a 30 mile drive down the interstate.
My brother was the previous owner and this has made the noise for years so it's not critical but annoying. I removed the dif. cover to change the oil. All the teeth are smooth, no rough or grinding surfaces. No play at the wheel end so I don't believe its a bad bearing. Oil was used but not burnt up or sludgy and very few metal flakes at bottom of housing. Thought it looked good for the age. Also, both wheels off ground and truck in neutral. There seems to be a lot of resistance while turning the wheel. I don't think the brakes are dragging but will eliminate that possibility this weekend.
What rear axle I have. Why its making the noise? How to repair it? Is this a posi diff?

I don't think I've heard it for a while but hearing them again. While driving car over some terrain (road, parking lot, parking lot ramp) that's not flat but curved up/down, as the car goes over it, I may hear a grinding type noise.
I don't believe it's the one where the bottom of car hits the road because of bobbing up and down and having low clearance from tires to bottom of car frame. I've heard that type of noise before as passenger in other people's cars.
Is this noise likely to be associated to some suspension component, axle, or the shock absorbers, etc.? I recently had the shocks replaced about a year ago, I hope the shocks didn't just die after a year. Other than that, car runs fine.
I did have tires replaced with new ones recently though if that makes a difference, car didn't go through alignment check though, just rebalance new tires.

My car has a distinct pull to the left when driving on a flat straight road. If I let go of the steering wheel the wheel actually turns about 5 degrees left of centre and the car goes in that direction.
Had an alignment from lexus edinburgh last year and again from another garage yesterday,
Still pulls and I have to physically hold the steering wheel centre when driving.
Car is 2011 IS F UK
Attached is my alignment spec from yesterday, Is it the caster issue as this can't be adjusted? If it is what's required?

When driving my 2006 F150 it drives real smooth until I hit 50, then it feels like I'm driving on a slightly bumpy road, once I hit 55, smooths out again. Only drives strange at 50 mph. Other speeds smooth as glass.

My F150 has started whining while driving down the road or sitting still. It gets louder as the RPMs increase. I have also noticed that the transmission has started taking longer / slipping going into 2nd gear. I also smelled the transmission fluid and it has an "odd" odor to it. Could the transmission going out cause this noise?
Here is a vid of the noise : 05 f150 - YouTube....

Transmission trouble on an 2006 F150 5.4 triton ... The problem I am having is when you are driving down the road once you hit 30 mph and it goes to shift into the its like it goes into neutral. It does that rill you slow back down to a lower speed then it shifts back down the transmission picks right back up till you get up to speed again, then it like it goes into neutral again. When I turn overdrive off it won't shift out of second gear. I have changed the valve body to the transmission to no success.

I have a 2008 toyora prius with 75423mi on it, was purchased with 70000mi two or three months ago. I have had no problems with this vehicle until recently. Being a prius newbie, I decided to ask here. When sitting parked on a slight slope earlier with the car running, radio running, and phone plugged in for an extended amount of time, I received an error on my display stating smething along the lines of "there is an abnormality with the p transmission mechanism, please part the car on a flat surface and engage the parking break completely" paired with a red triangle on the dash. I immediately moved the car to flat ground and engaged the parking break. The car turns one, shifts fine, and acts just as normal as prior. Is there anything I should be worried about? The car is still under toyota warrenty and is due an oil change now. Any clue what the cause of this was and if it will be reoccuring?

At a loss right now. My 2004 F150 4X4 and just recently started sounding like the truck is trying to shift into 4X4 mode while driving it. It stops if it's switched into 4X4. I have taken it to a local mechanic shop I use and they said it was the Actuators and they replaced those. I got it back and the same day the noise came back. Took it back and they have had it for another week and still unable to figure it out. I even took it to another shop that was highly recommended and they say to take it to a Ford dealership. I have read that some say it could be the vacuum operated hubs? Need to figure out what it was and had it fixed?

I have a 2003 f150 with a 4.2 v6 2wd and about 116 on the clock.
It has this annoying, faint squeak whenever i hit bumps in the road. Sort've sounds like bird chirps. I cannot reproduce it if I bounce on it while parked.
One rainy day I tried to show a friend and it would not make the sound it seemed. Therefore I think its exterior, although it almost sounds inside.
Today I sprayed down all the rubber joints under the front end with silicone spray. It still squeaked while driving afterwards. How else can I go about diagnosing this?
I should note that a ford dealer claimed the ball joints were worn and needed to be replaced. Although, would a ball joint make bird chirp type squeaks while driving at most speeds (20mph - highway speeds)? It does not intensify or change at any particular speed.
My understanding is that a bad ball joint would grind when turning the wheel or clunk while traveling over speed bumps or something similar.

I was just wondering if this is normal. On flat road I can coast without touching the gas pedal and go 15mph. Is the idle set up too high?

About 3 weeks into the new 13 Elantra. Liking it pretty good. I seem to be hearing a noise of some sort. Almost sounds like a flat spot on a tire. Seems to be more rapid the faster I go and more or less noticeable on different types of asphalt. Didn't really notice it at first. The only thing I did was let some air out of the tires. They had almost 40 psi when I got it. They call for 32.

Our 07 RX350 has 47,000 miles and I just starting to hear (I think from the front) a faint rattling noise while driving. It's hard to describe but it sort of sounds like what you might expect if an empty plastic bottle was slowly bumping around in a plastic box. It is not a metal on metal type of noise. The shocks/struts appears to pass the old bounce test and the car does not seem to display any of the handling issues you get when you have worn shocks/struts.
I also checked the upper engine compartment to see if any plastic shrouds or covers were loose - they weren't.

I drive a 2008 Ford Expedition and every time I go on long trips after a while on the road the car starts making this grinding noise when driving uphill. As soon as i take my foot of the gas it stops. It has never done it in the city, always when driving on the freeway. I can manage it if I keep the gas pedal as steady as possible but if I try to give it more gas it will start making the noise. This does not happen all the time, it is intermittent. I was told that it might be the 4x4 engaging on the front wheels but I am not sure what it has to do with the speed or gas. I have changed the spark plugs, fuel filter, fuel pump.

My boss' truck has a bit of a stumble. While going down the road between 40-60 MPH it will kind of stumble. While it's an intermittent problem, it seems to happen when climbing a slight grade. I plugged a diagnostic tool into it and got no codes of any kind. He had it at a trans shop, thinking there might be some trans slippage, but the shop said the trans was fine. The vehicle in question is a 2006 F-150 Lariot 2WD with a 5.4, auto trans...

Its actually on a 2008 E350 with a 5.4 but figured its all the same. There is a squeal that sounds like a bad pulley but its coming from the flexplate or torque converter. I have taken the belt off to verify. I dont see anything psychically wrong like cracks, bends or anything touching. The little I can find on this subject I would say flexplate has a crack somewhere. Transmission shop also can not figure it out. I just want assurance before pulling the transmission in this beast.

A few days ago I felt a feeling of bumping on a flat road when I turn slowly. I was wondering if it might be a transmission shift shock due to an insufficient warming at the cold temperature. It seemed such bumping didn't happen after enough warming more than 5 minutes.
The outside temp was just above 0 degree on yesterday morning, I started SF without warm-up and drove about 15 minutes. Then I was making 3 point turn on a residential road covered with a little bit of ice on its edge when I felt one of rear wheel was slipped a bit on the ice and rear wheel got locked or seized and skipped. Upon the complete turn I was able to drive the SF home slowly cautiously, however every time I made a slow sharp turn left or right there had been skipping leaving tire marks on the driveway.
I thought 4wd lock was initially activated at that time and it had not been deactivated since. I tried to push and release 4wd lock button several time with no success, and I felt the SF moving very heavier than usual. I was trying to park the vehicle backward with a sharp turn too, it was much harder to turn back than forward feeling like rear wheels were stuck somewhere, suddenly there was a loud banging or thumping sound from bottom behind. Right after the banging the SF was moving as normal.
Today I tested SF by driving above 60km/hr as well as sharp turning for 30 minutes, everything looked normal. A couple of hours later I decided to test 4wd lock button again. While I driving SF at about 10km/hr I pushed 4wd lock button and released it 15 seconds later. I did it a couple of times because I was not sure if 4wd lock was activated and deactivated. And I was making 3 point turn again, then the same rear wheel seizure and skidding happened. I stopped the SF and I pushed and released 4wd button a couple of times with no success.
Finally I tried to turn back as I did before, and there was a banging sound, I thought the sound was weaker than yesterday, since then everything went back to normal. There is no grinding or clunking noise from the area where the differential unit is located. I was wondering if mine has faulty electronic clutch itself or any other components. The warranty was over 5 months ago, mileage is only 49,000km.

so im a fairly new owner of a 2008 f150 lariat 4x4 5.4l3v bought in September of 2013 with 32358 miles. this engine was built in 10/9/2007 and was just before the spark plug update so I have the black cop on this engine. and on cold day start ups it sounds like a diesel till warm and then it still has a slight knock to it vary slight is this normal or is this a tall tail sight of the phaser issue or spark plug issue coming to light love this truck and will fully rebuild it if I know what to do, ford dealer says that its normal and that if I lose power at some point I will need a new engine with this low mileage.

The steering wheel on our Prius is not centered when the vehicle is on a flat road going straight.
