Ford Super Duty (1999-2016) :: Rumbling At Idle / Sounds Like Metal On Metal Vibration
Nov 24, 2014
Just last night, out of the blue, I've got an odd rumble at idle. The noise goes away under load and any time the rpm's are up over ~1300. It sounds like metal on metal vibration, but I don't see any loose exhaust parts.
I've looked at threads saying possibly a broken flex plate. Other than the noise, would there be any other symptoms? I don't notice any loss of power. I suppose I could pull the inspection cover and take a look, but I don't have any experience with auto tranny's and don't really know what I'm looking for.

I thought i heard this yesterday when i left work but i was tired and said its in my head, THEN i go to leave right now and sure enough its a real sound, you can hear it very well through the front grill and then if you turn the volume up you can hear a ticking sound ever half a second or so, it also speeds up when i was pulling on the throttle cable. And after the truck fully warms up it goes away.......

What we have is a 2011 F-350 with the ambulance package (obviously) and it has started making a very annoying sound from the front end. It has been into two different Ford Dealerships and they have not been able to remedy this issue. What happens is, when we are backing and turning, the front end makes a bad metal on metal grinding noise. When going straight down the road no issue just turning while backing. I know this is an ambulance and has the ambulance package but I think from the cab forward should just be all ford right?

I have a loose, binding, metal on metal sound on my steering wheel shaft. I have removed the steering wheel, replaced the clockspring, because when I removed wheel clockspring was in pieces and I thought that might be the issue. Guess not, because I'm still having problem. Other than having to remove or replace the whole steering column...

2012 Passat SEL ... I got new tires put on a few weeks ago and have a new rattle, sounds like glass tapping against glass or metal on metal. It only happens when I'm cruising around 65 mph. From where I am in the drivers seat, it sounds like it's coming from the drivers rear tire area or under/behind the center console/dash board. I know it's not a lot of info, but need to figure out what's going on.

Tires just balanced and rotated yesterday (second time just in case done wrong before). New ball joints and bars installed about 50k ago. Left front shock may be bad, but only slightly.
The issue: At about 40-55 mph, there is a rumble in the cab, unknown origination. Everything vibrates, although it "seems" like the left mirror is shaking more. The seat, floor, steering wheel, everything vibrates.
When I let off the pedal, vibration and noise go away, even within the "vibe zone". It only vibes when any throttle is applied, even just a tickle. I brought the engine up to the vibe zone RPM (1500-1800'ish) while in park and neutral, all seems fine.
I checked the U-Joints, they seem tight. I don't have access to a scanner, unless I want to pay the dealer.

There are 2 metal straps going left to right between the rear seat mounts. They don't appear to do anything. The seat doesn't touch them. The mounts are bolted to the floor so they don't give support. What they are for?

My automatic shift selector was extremely loose. Wasn't the two bolts up behind the dash. Turns out that there is a metal cylinder with a cutaway that seems to have fallen out of the selector housing. One of the edges of this cylinder broke off as you can see in this pic:
What is this piece called and can I get a replacement at autozone/pepboys/ect?

I have an issue with a truck I recently purchased. I have a vibration that starts around 50, feels like a wobbling vibration. Than once I hit 75 it feels like the truck is going to fall apart. Heavy rumbling.
It's a Ford F-350 dually extended cab. With 115,000 miles on it.
I took it to the shop to balance out the wheels and all the wheels needed atleast 2 oz of weighs on each side. Some have as much as 4.75 oz on one side. Is it possible that I need 6 brand new rims?

I have a 2001 F350 with a 7.3 diesel and automatic trans. I purchased it about 100,000 miles ago. It is all stock as far as I know. The mileage on it was about 14-15 on the road and I decided to put a chip in it. I was somewhat leary of putting too much power to this old of a rig. I put a TS Performance chip in it. It seems to have more power. I am towing a 30 ft. Gulfstream Seahawk I think around 10,000 lbs. When I started up a hill it made a different noise like a screeching noise when I pushed it. When I back off a bit the noise goes away. When I put it back to stock setting the noise is not there just the normal downshift and increased RPM. Not sure how to describe the noise but sounds like a metal bearing type noise. I get the same rush of air or what ever that sound is when it changes back to a higher gear. Is this sound normal or what might it be. It sounds normal when not pressing it.

I may have got a few shavings in the engine while drilling and tapping a hole for my boost gauge on the Y pipe. I am sure I got 95% of the shavings out but am now worried about the 5% that may have fell inside.

I trying to see if this is something that is a easy fix or mayor work. Leak coming from that metal housing behind alternator. Does this housing came off? or do I need to take out the intake out? .

So, Saturday my abs lite comes on. Later that day I hear metal to metal sound for a couple of secs then it stops. Then the next day while driving I get intermittent sounds that sound like I'm dragging metal down the pavement. I see nothing but I'm thinking hub bearing. (Needle)
I remove the hub assembly from the knuckle and can find nothing wrong. I even picked up a new hub just on case. Now I'm stumped. Can't figure out what the sound was or is. Axle has a little play going into the housing but figure it would have due to the only thing holding it in place is the hub.
The only thing left in the area that could make the sound is major --the actual gears to to the front end. If the bearing isn't causing the metal grinding sound I've no other idea other than that....

I bored and tapped one of the spark plug holes in my Triton engine. And I used a long aluminum rod attachment for my air compressor to blow out the metal bits from inside the cylinder. I started with a full tank of air, and used it all up to try and get everything out that I could. But with my bore-scope I could see a lot left over along the edges of the piston. So two more times I filled up, and emptied the air tank (15 gallons, 150psi). Some more of the chips came out, but after the second time there were still some chips there, and the third time didn't work much.
My bore-scope doesn't have the best resolution, but I think there are a few chips that are stuck between the piston and the cylinder wall. Since there were only a few, and they are aluminum, I decided to do what I saw another youtuber do. I just started the engine for a few moments without the spark plug, so I might blow out any remaining chips (although he did it without first using compressed air at all.)
That was the first cylinder I bored, tapped, and installed an insert into. But for the other cylinders, I would like to avoid any metal bits left in the cylinder. But I can't think of any way to prevent some from wedging themselves between the piston and wall (if that's what is happening).

My 2000 f250 4x4 V10 5spd manual with LSD and 63k mi gets an intermittent but very strong vibration like a shuddering, growling, rumbling in 2WD. The 1st time it only lasted about 1 second. It had been making a swooshing noise that sounded like front left wheel bearing for several thousand miles before this, so i replaced bearing assembly even though it turned smoothly.
After that, It still made the exact same swooshing noise and after a couple miles at 45mph, it had the strong vibration/shudder that lasted about 3 seconds. I stopped and locked the hubs manually. The vibration happened again in a couple miles, so seems like it's not the needle bearings in front stub shafts or locking hubs. On that last occurrence, the vibe went on for 5 seconds, felt the same with clutch in, and went away only after truck slowed down to nearly a stop. I've driven it about 6 mi total since the 1st occurrence.
Front right Wheel bearings feel smooth. I unbolted the driveshaft support bearing and it spins smoothly. The front u-joint maybe had a tiny bit of play, all bolts tight. I didn't check the nuts for yokes, but it didn't look like yokes had any play. Drive shaft slip joint moves smoothly. No up-down play at pinion shaft input into rear diff and output from transfer case. Rear diff oil was full with a little bit of silvery sludge on the magnetic filler plug, maybe 1/10 of a cc, no metals slivers or chunks. I raised the rear wheels and ran 5th gear 2WD at idle (~30mph) and touched a 4' listening stick to the drivetrain components.
The only odd sounds were from the rear differential. It sounded like a bad bearing with random crunches and thuds mixed in with the normal whirring. Crunches and thuds were loudest at front of diff housing. I blocked one wheel and repeated in 3rd gear. You could hear noise like gears meshing (noisy spider gears? maybe was LSD clutches?). The differential was warm after 5-10 minutes, with the hottest area being about 3" from the front of diff, just before the housing widens.
So, I'm guessing the pinion bearing is bad and the intermittent shudder is the bearing race spinning in the case when bearing seizes.

I am in the process of replacing my water pump. After I removed the pump, I found quite a bit of metal-on-metal wear between the impeller and the water pump housing. Is this common?
I've been running a coolant filter on my system for years now, so hopefully its been effective at collecting some of the metal that has clearly been worn away. Either that, or this is a sign that the filter isn't working at all!
I'm a little worried that the new pump will scrape the scars left from the old pump.

I replace my brake pads and rotors in the fall of 2015 with EBC parts. Now almost 13,000 miles later, I started hearing grinding and metal-on-metal contact in the front. So I went out and got PowerStop pads to replace the EBC (EBC had way too much brake dust). I took off the front wheels and noticed that the DF pads had about 1/32 left on them, ok I guess its time to change them out. Onto the PF pads, I find that there is almost no material left, in fact I could scrap off what was left of the material. I decided to do a rotation while I am at it and noticed that the rear brake pads on both sides look like I never used them!! Is it really that possible to have 2 stuck calipers, both on the rear at the same time?

I have an '02 Taurus. For the last year or so it has intermittently produced a metal on metal grinding noise while failing to start up. I'm told this is due to teeth being missing on the flywheel between the starter and the transmission. It's taken as many as six tries to get the car going. But the car has always started in the end.
My questions are: Is the problem flywheel worth replacing at this point at this price? Is it likely to fail totally any time soon?
Also, might the March '09 replacement starter be implicated?

I have intermittent metal on metal grinding noise. Seems to happen when I am at highway speed. Seems to go away when I put it on 4 wheel drive or slow way down. On one occasion though, the grinding noise did not stop even after putting on 4 wheel drive - had to stop completely before it went away (did not come back after I drove off again). Diagnostics so far....
Unhooked the vacuum lines on passenger side actuator and hooked up vacuum gauge. Vacuum held at 20 psi and drops and raises slightly as the truck is being revved. Takes about 10 seconds for vacuum to drop to zero once truck is stopped. Putting it on 4 wheel drive drops it to zero immediately. Exact same scenario on the passenger side.
This leads me to believe my IWE solenoid is ok. So also my check valves. Next opportunity I get, I will raise one wheel, remove the vacuum line on that wheel and apply vacuum with my pump. Want to see if it will turn my half shaft.

My father's 1997 F150 with the 4.6 two wheel drive, has me stumped again. I have a lot of mechanic knowledge but this one has got me wondering whats going on. Here is the run down. When you are driving down the road, it rides just fine and makes no noises from 0-20 MPH, after about 25 to 35 mph it makes like a metal on metal noise that is coming from the rear, and forces the truck to slow down, when you try to accelerate through this problem it has a bad bang and it wont allow you to speed up anymore, it does not seem like a brake issue (but I could be wrong) since it does not actually pull to one side or the other.
It seems like an equal force trying to stop the truck. I have heard rear ends that were going out and they make clunk noises or whirring noises etc, but its still some what driveable. I have checked the rear end oil and it does have oil in it, and its probably about an inch from the full level (but that shouldnt cause this issue im sure). My father wants a definite answer before we start tearing this thing apart to try and fix it. Since its mostly used to take trash off, and also get the kids down the dirt road to the bus stop.

Getting the RV ready to go for the summer, and no a/c. I started to add freon, and found the leak right away.
It's on the 3/4" pipe that goes right over the upper radiator hose; obviously rubbing metal to metal caused the pinhole. Now I know where that mystery green snot came from all over my radiator hose coming back from Yellowstone last fall.
First thought was to replace the entire pipe. There's an easy threaded connector on the upper end, but way down on the compressor is a strange fitting that looks like a triangle stuck against a cube. I can't see how I'd get a wrench in there very easy anyway. What is that fitting?
I bought a Dorman 3/4" repair kit, but until it arrives in the mail I don't know if I've got enough straight pipe to work with. Do I need to add oil as well as freon once I charge the system again?
