Elantra MD (2010-15) :: Metal On Metal Noise When First Accelerating

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.

Touareg :: Noise (metal-on-metal Rubbing) When Turning Steering Wheel

I have a base v6. When I turn the steering wheel (for example, to make a left turn), it sounds like there is metal-on-metal rubbing. The wheel is not extended (turned all the way til it stops)...

Ford 6.0L Power Stroke Diesel :: A/C Leak Found - Rubbing Metal To Metal Caused The Pinhole

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?

Prius (2010-12) :: Metal On Metal Grinding Noise At High Speed Above 75mph?

I commute 180 miles a day, 6 days a week. I noticed metal on metal grinding noise(more noticeable) at high speed above 75mph especially on asphalt road. I'm sure noise is there at low speed but not enough to notice. My car has 50,000 miles. Tires? Electric motor?

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.

Camry :: 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.

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.

Ford Super Duty (1999-2016) :: Metal On Metal Noise From Front End

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?

Prius (Gen 2) :: 2006 Metal To Metal Noise While ICE Charge The Hybrid Battery

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 - 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.

2004 F150 FX4 ....

Ford 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.

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.

Honda - Accord :: 2009 - Metal On Metal Noise When Driving

My 2009 Accord is making a metal on metal noise when I drive. It's not all the time, probably about 1/3 of the time or so, and only when I'm accelerating/cruising, not braking. It's very loud, and when I took it to a mechanic they just took it for a ride, didn't hear anything, and told me to come back when it's more consistent. What it could be? I'm nervous even taking it out now.

Ford 7.3L Power Stroke (1999-2003) :: Light Metal Rubbing Noise Coming From Front Left Wheel

I have developed a sounds that sounds like metal on metal. Not a grinding but more of a "swish swish swish" light metal rubbing when the truck has been running a mile or two. I can barely hear it over the radio but its very noticeable when the window is down. It is not affected by the pressing the brakes and it gets louder and faster in direct portion to speed. It will occasionally leave and start right back up. I touched the front rim around the hub and it was hotter than I wanted to hold onto. It didn't burn but it was hot. It was 105 degrees that day. Here is what I have done.

I replaced that front hub in 2010 and probably have 50K miles on it. I did the 3-9 test and there was no noticeable play. I spun the hub and while it seems to spin ok it does seem a little dry.... I will pull it tomorrow and see what it looks like.

I pulled the calipers off and the brakes pads are at half way and there is no burnt smell. I spun the rotor and it seemed flat and straight. I do have a small tiny lip all the way around them on both sides but I figured that's normal with 265K. I pulled the pins and they were dry but they didn't seem to be sticking. I cleaned them up with the boots and am going to replace them when I get some brake grease tomorrow. I have not looked real hard at the caliper but I plan on pressing that with a C-Clamp tomorrow to check it. Since the rotors and pads looked OK, I assumed there was not a stuck caliper although haven't ruled it out. The axle behind the hub seem to spin freely before I removed all this stuff and the hubs are not locked.

I think I covered it all .. I also thought it could be a rock or stick but nothing came out of my caliper or rotor when I took them off ..

Elantra MD (2010-15) :: Front Wheel Metal Squeak During Acceleration

My parents own a 2013 Elantra 4-door (sedan) and for the last few months it's been making a metal grind/squeak. Here are the following characteristics:

-It occurs only during acceleration from a full stop or low speed. It would then disappear if we drive it longer or get to 60km/h.
-We've diagnosed it to the front right wheel.
-It sounds like the squeak at you get when your break pads are almost used up - metal on metal grinding squeak
-It seems to be temperature related as the squeaking occurs less during cooler temperatures - it comes back once (I assume) the wheel / brake / rotors are sufficiently warm.

We have brought it to a mechanic and he did hear the squeak. He took of the pads and re-lubed (not on the braking side obviously). No change. BTW the pads are still very beefy and is the original pads that came with the car.

Searching online it seems this issue is fairly common and it seems to be the brake pads. Is this what's happening to my parents' car? If so is it as simple as replacing the brake pads with a different brand?
