Prius (2010-12) :: Light Metal On Metal Grinding Noise
I have a 2011 Prius with about 32K miles on it. I've been hearing light metal on metal grinding noise for a few days now. So I decided to take it to a stealership and they told me my ceramic pads and brake rotors both need to be replaced for all 4 wheels. I thought Prius brakes don't need to be replaced for 100K miles.
View 7 RepliesFord - Taurus :: Metal On Metal Grinding Noise While Failing To Start Up
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?
Ford F-150 (2004-2008) :: Intermittent Metal On Metal Grinding Noise
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.

Elantra MD (2010-15) :: HVAC Blower Noise / Metal On Metal Rubbing
My Elantra's HVAC fan has always been a quiet thing, even on 3.....we won't mention level 4 and the fact it sounds like a 747 at takeoff.
I kid you not, the very evening I hit 60,000 miles and the general warranty expired, the blower motor started making noise like it was throwing a bearing and definitely sounded like some light metal-on-metal rubbing. After I became irritated at this, the noise went away and didn't come back until just a few weeks ago. I could make it stop by smacking on the bottom of the fan assembly a few times but I want a more permanent solution.
Tonight I dropped the blower out which was stupid easy except for the fact you're upside down in the dark with your head in a hole. But three screws and an electrical connector later, I dropped the assembly to find no serviceable components. I mentioned this to friend of mine who's into Volvos suggested spraying some lithium grease on the hub of the blower and letting it run long enough to quiet it down. I'll do this over the next few days and report back but part of me thinks a new blower may be in my future.
Prius (2010-12) :: Metal-on-Metal Whining Sound While Running
I own a 2010 Toyota Prius that recently developed a metal-on-metal whining scraping sound when moving. It does not make sound when the vehicle is stationary, and it's intermittent - which makes me discount the rock-in-disc-rotor idea (not eliminate it, mind you). It's quite loud when it occurs, able to hear it over the stereo. Luckily I was near work at the time, so I went there - but the shop can't even look at it until Monday evening - so I am a bit panicked.

I have a 2012 Elantra with 21000 miles on it. It runs well but in the last month or so it has started to make a strange noise when first accelerating. I would describe the noise as touching a fork to a metal fan...kind a "zzziiiinnnkkkk" sound, I guess. It only happens when the car has been sitting for a while and only on the first acceleration, usually in first, second, and third gear after which it immediately goes away and doesn't happen again until the next time we drive it. It seems like it would be related to the transmission except the sound is too tinny for it to be the gears. It sounds more like sheet metal making that sound. I took it to the dealer but they said they couldn't make it make the sound, which is crazy because it does it EVERY time we drive it.

I recently worked on a 2006 with 140K miles that presented with the following symptoms:
The hybrid battery was at 1 bar; the ICE would not start; the car was in Ready, but there were no codes. As I let it roll off the flatbed wrecker in Neutral, it felt lumpy. If you have ever pushed a car (or run out of gas in one) with a manual transmission that was in a high gear, engine off, it felt just like that.
I popped the hood and could see that the engine crank was turning while the car was being pushed in Neutral. What else turns with the wheels? MG2, or more specifically, the MG2 ring gear. What is the only way that the wheels could turn the ICE crank? The planetary carrier pinions were locked to the ring gear.
Surprisingly, while I was looking at things, it did manage to start the ICE pushing it around must have freed the carrier pinions, so I let it charge the hybrid battery. It was basically the worst metal-to-metal noise that I have ever heard! I pulled the drain plug and saw about a teaspoonful of large metal chips on the magnet. The fluid condition itself was very good, not the black factory fill that I am used to seeing come out.
Ford F-150 (2009-2014) :: 2011 - Grinding And Metal-on-metal Contact In Front
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?
View 2 RepliesGolf V R32 :: Clunking / Metal On Metal Grinding Sound
This morning on my way to work, pulling into the parking lot around 20mph. I hear a metal on metal grinding noise. (almost to the sound of a muffler dragging on the ground type noise). Then that disappears for a bit, hear a loud metal clunk then some high pitched sound. All within say 30 seconds. Definitely coming from the back, but can not tell from which side.
Things I've checked in the parking lot:
Nothing hanging low, exhaust seems in-tact
It doesn't look like the brake shields behind the rotors are bent or touching
Sounds still happening if on or off brakes , on or off throttle.
It seemed to happen only at lower speeds. Disappeared once I got up to 50mph
Just took it out for a drive, that loud metal clunk happened when I put it into reverse, drove around, no other sounds. I just don't have a warm fuzzy feeling that this will just disappear.
Subaru - Outback :: 2002 - Metal On Metal Rattle With A Very Slight High Pitched Whistle
Yesterday, I noticed a rattling sound coming from the entire car a 2002 subaru outback 2.5l 4 cylander (it seems a bit louder on the passenger side but it literally can be heard throughout the car). I was on the expressway and got off and stopped at a red light when the check engine light came on and started to flash and the rpm's dropped rapidly and the needle began to bounce up and down. I pulled into a gas station to check it out more and popped the hood to find that when the car is rattling it is also shaking and rocking the engine of the car from side to side slightly.
When I'm idling the rpm's drop and the car feels like it is going to stall out. Then, as I accelerate, the rpm's barely go above 2000 and jump up quickly between 3000 & 4000. It sounds like a metal on metal rattle with a very slight high pitched whistle and you can hear a fan kick on and the engine try to keep the rpm's up every couple of seconds when the car is stopped. I had the timing belts replaced 2 years ago and it sounds very similar to how it did when they needed to be changed, however, the engine never felt like it was going to stall until yesterday.
When idling the noise gets louder and when accelerating it can still be heard but barely. Also, the rattling has caused the entire car to vibrate all of the time. I noticed yesterday that the oil was low and topped it off, but I don't think that would cause such a hige issue so quickly. When I go uphill, i have a good amount of power but every 30 second or so the car shifts and the rpm's jump lurching the car forward because of the surge of power. Also, when I hit the brakes, my rpm's jump slightly to about halfway above the 1 but the engine does not accelerate.
Prius (Gen 3) :: Metal Grinding Noise When Braking
I've read a few posts about the Prius braking system. Just wondering what other owners have done when they experience the metal grinding noise and when brakes need to be replaced. My car has around 67,000 miles. I was planning to take it to a Toyota dealer, although prefer to find a certified Prius or hybrid mechanic at an independent shop.
View 3 RepliesCamry :: 2010 - Passenger Side Rear Brakes Making Metal On Metal Sound
At 75K my passenger side rear brakes were making metal on metal sound. I was really surprised as I have always learned that the front brakes take 80% of load and they always go out before the backs. So I took the wheel off and sure enough the pads were metal on metal. Changed everything out. (new rotors). I then went over to the driver side rear brake. Looks brand new. The pistons were barely out. I figured this caliper is bad. (I haven't change yet)
When I drive I can hear a very faint metal on metal sound when I brake. VERY FAINT. So with 75K miles on I figure the front brakes are due. Today I took the wheels off and inspected them. Tons of pad left on both of them. If I didn't know better I would say a brake job had been done very recently. (I've owned the car new so I know they have not had a brake job) However after reading many articles on this site I found a thread where one user said he was changing his front brakes for the first time with 110K on them and the pads still had 10K left in them. So the fact that my front pads are still pristine at 75K may not be a big deal (or not as big as I thought. Also I am not hard on brakes.)
However I'm not sure what is going on. Why would the passenger rear brake be metal on metal at 75K and the three other pads are like new. Is the passenger rear the only one working (or working much harder than the others) meaning the other three are bad? Or is the rear passenger bad and the other three are good? I have a working knowledge of cars but I am by no means a mechanic.

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?

View 2 RepliesFord F-150 - 1997-2003 :: Metal On Metal Noise Coming From Rear After About 25 To 35 Mph
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.
Lexus IS 2014+ :: Metal On Metal Noise Coming From The Rear?
When driving in my parking garage, I can hear a slight metal on metal noise. An extreme example would be sharpening a knife on a sharpener, its not as loud or predominate.
-I've checked the lugs, they are secure.
Car has springs and spacers.
Golf/GTI VI :: Screeching / Metal On Metal Noise When Engaging Clutch?
For the past few months, pretty consistently, whenever I engage the clutch from full stop into first gear (it does it when starting in second gear too; and reverse) there is a pretty obnoxious and loud screeching noise that I would liken to a subway/train braking or just metal on metal grinding situation. When I took the car in to Douglas for an oil change and APR Stg 1 flash, they told me it's just the brakes being cold, etc. After driving the car some more, I really doubt that it's the brakes and I can reproduce this regularly by slowly releasing the clutch and get the noise usually just before the gear engages.
That car has just over 16K on the clock and has never been abused. The clutch pedal feels fine and there is no issue shifting into any of the gears other than the noise. No mods other than the APR Stage 1.
Honda - Cr-v :: 1998 - Making Metal On Metal Ticking Noise
My 98 CR-V is now making a metal on metal ticking noise. The noise only occurs when the car is in motion. The noise seems to occur about every two revolutions of the wheels when moving slowly; I can't determine if the ratio holds true at higher speeds. The noise seems more prevalent when standing on the car's passenger side, but not significantly. The car has 225K miles.
