I ease off the brake and i hear this rattle coming from my car, like metal on metal. But really high pitched like something got loose or something. Tick tick tick tick. So i give it gas and it goes away. Its only there if i brake and release the brake...So i get home and everything is normal. I go outside and move my car and there's the weird rattle again ...
View 21 RepliesYesterday, 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.
I've been hearing a metal on metal sound coming from the brakes. I checked the pads with the wheel on and they all looked good. The back were replaced before I bought the car back in October. Last night the brake warning light came on, so I brought to my local shop. Longer story short, the inner pad was completely worn out, but the outer's were good.
View 2 RepliesI picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.
View 5 RepliesFor 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.
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.
I have the eip street series catback- that is it for exhaust mods.
Every time (when car is cold) I start out in 1st, just after I release the clutch (1100 rpms or so) I hear a slight metal rattling noise for a second or two. It sounds as if it is coming from near the cats. And the noise disappears after the car warms up.
What it could be? Is there a heat shield above the cats that might rattle?
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?
View 7 RepliesI have a 2007 hyundai sonata, this car is my daily driver. I put 180 miles on it a day around trip. Currently has 180,200 miles on it. Last Friday on my trip home when i turned right I heard a metal on metal sound. I slowed down went straight and it went away. Talked to a few people and I think it may be the wheel bearing. Even if I hit a road reflector it starts up. It's the front left wheel. Get on the breaks it goes away.
So my question is... Wheel bearing??? And can I replace the whole hub and fix the problem or do I have to try and press the bearing out?
I got some coilovers installed last night, they are ksports. i have them on fairly low height as of now but i have noticed every time I hit bumps, I hear a kthunk (metal hitting metal noise) from my front driver side. is it from the coilover nuts itself or something wrong with my control arm? the sound ONLY comes from the front DRIVER side.
View 4 RepliesI have a 2003 Toyota Solara 4 cyl. auto. transmission. I recently had the head replaced. Now it is making a metal on metal sound near the drivers side of the engine. It makes the sound during idle, when I change gears, and the sound increases when I rev the engine. What could it be?
View 8 RepliesI 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.......
View 14 RepliesI 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 RepliesWhat 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 RepliesI 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.
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.
My 2011 2.4l Sonata made a metal on metal sound suddenly the other day. About 4 days ago, I drove about 2 hours away from where I live, Mostly highway, about 80mph to a go kart race. Got out of the car for a while and came back in and was pulling away to run the store and as i started to approach the first stop sign maybe 500-600 ft from where i was parked, i heard a bad metal on metal sound, came to a complete stop at the sign and it stopped. Went back to the race after driving to the store about 5 miles away.
Got in the car to leave and same thing, just to the stop sign 500-600ft away. Drove home like i said mostly highway, and didn't hear a thing. Today, about 4 days later, I drove to Chicago O'hare airport, about 30min away, and it was fine the whole way there. However on the way back, after about 20-25min, I heard it again. So I came to complete stop as I was forced to by a traffic light as I was taking my exit off the highway, and It started making that sound again. So i came to a complete stop at the light and started moving again when it turned green and couldn't heard a thing.
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)...
View 2 RepliesI 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?
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.
View 1 RepliesI 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.
