View 2 RepliesI have an 06 grand Prix, about a month ago I started hearing a knock on the front driver side n it has gotten worst. At first I thought it could be a hub bearing or tire rod ends but I noticed service abs and traction system lights are on.
View 4 RepliesIt only seems to happen every few days. I have noticed it when I come to a stop, then I hear a repetitive knock coming from under the front passenger side of the car. knock, knock... 7 times, in rhythm, not decreasing in volume, then it stops. Kind of like a gnome trying to get in from under the car... It does not sound like something is flapping or swinging as the knocks are consistent, it sounds mechanical in nature. The car is at the dealer right now for that and other things but they cannot get it to make that noise.
View 8 RepliesSo I took my 15 Passat sport into the dealer this morning because of an odd shuddering sound I was getting from the front suspension. Of course the car didn't make a single sound while we were there.
Then tonight when I went to back into a parking spot I heard what I first thought was the typical groaning of pads and rotors slowly moving except that I wasn't.
Check this out .....
This is simply me going from reverse to drive. No change in brake pressure and no movement at all. Shuddering type noise when hitting drive way or steep speed bump at an angle? I can feel it through the steering wheel.
Every time I am pressing the brake pedal, I hear a distinct clicking sound coming from passenger front Brake Caliper Area.
I have applied brake grease (green) to the pad shim.
I have replaced the spring sets on each front caliper.

After my coilover install there is a small knock coming from both sides in the front that wasn't there before..sounds and acts like a swaybar link but they don't have play and I replaced them and the noise is still there. I also reused the the shock tops?

I have an 03 Elantra and before joining this I have never paid much attention to the sound coming from the engine but now that ive seen a few videos and looked at some threads I think the engine in my Elantra knocks a bit.
Here is the video i was referring to in comparison - YouTube
It sort of sounds like this but a little less intense. Its definitely knocking but not as loud as the video. It does it all the time, not only when its cold but when its warm too... Its always sounded like that but I haven't ever paid any attention to it.
Anyways... after a whole day of reading about gas and octane and all that fun stuff I am not sure whether to try midgrade or primium gas...
I just picked up my car after having a shop install ball joints, tie rod ends, and end links and there is a thumping sound coming from I'm guessing the right front tire that is consistent with speed. I had an alignment done today as well. Is it possible that my newish tires are already worn unevenly and the alignment is showing that now?
Either that or the wheel is not seated completely. I'll call the guy back tomorrow when they open and let him know what I hear.
Only reason I didn't so it myself is because its cold out now and he did everything including alignment.
I have a 2003 passat. I have noticed, and its getting gradually worse, a knock that comes from the dash. I get one knock when I go round a corner and then a similar knock when I go round an opposite corner. Its as if something is rocking from side to side.
It sounds like its coming from behind the dash just off center to the left. Perhaps behind the passenger airbag? Its difficult to tell exactly.
I recently bought a 2007 Passat 3.6 and am now noticing an odd sound from the motor. When I am at parking lot speed, just barely giving it gas (1000 RPM or so) I can hear a dull, almost rhythmic knock coming from the motor. It's similar to an exhaust "lub-dub" sound, but not. I brought it to the dealer under it's bumper to bumper warranty and they told me that it is a normal sound for the vehicle "in this configuration". Is this really normal?? I'm worried that it isn't, and just about the time I'm out of warranty it'll be a big deal. The car has 32K on it and the engine has 20K. Yep...it blew and was completely replaced at 11K.
View 2 Repliesthe other day i was driving with no music on my GS and i noticed every time i came to a complete stop, the brakes would produce a weird loud knock sound. it was rainning so i thought it would be from that... but then after driving it roughly 5-7miles the sound stopped... then since i noticed it, i hoped on my corolla to see if it had the same thing but no... only on my GS.. is this normal?
View 5 RepliesThe tweeter and the speaker in my passenger side front door have this awful hissing sound coming from them. The sound gets louder and quieter with driving. Could it be a lose connection at the headunit or would it be to each speaker? The speakers are stock by the way.
View 3 RepliesI bought a 2002 W8 92k Miles from a dealer for a very cheap price, KBB 9k, i paid 2k because there was a engine knock *gasp* i know. The body/interior is in good shape. From what I was told the noise was coming from the 'upper' part of the engine..I was hoping it was probably a bad lifter, not a big problem. So the car was trucked to me yesterday, it drives fine still but the engine noise was more severe than i thought. I'm 95% sure it's a spun rod bearing. I'm stressing .
I own a 2 ton gray monument. I cant spend that much money right now on just an engine and a rebuild might be just as expensive. I'm hoping (I need to stop that) that maybe i can drop the oil pan, inspect/remove the rod caps and maybe replace the bearings or push the pistons out the top. In my mind I know the crankshaft was probably scared too but im keeping my hopes high that it wasnt. If thats the case then the whole engine will need to be removed.
I know it not a good idea to buy a car with a knock but that was the condition or the purchase. I want to atleast try to get an idea of the work needed before considering parting it out.
I have a 2003 Volvo C70 that I've owned since 2004. In February, I ordered struts for the front with all the trimmings, (spring seat, strut mount, bump stop, etc) from FCP Euro. The struts were Sachs 553-058, which are supposed to be as good if not better than the original struts. I installed them myself, meticulously following the instructional video FCP publishes on YouTube. Installation went very smoothly. Afterwards, I noticed a rattle/knock coming from the right front when I drove over a bump or rough area.
I took it to a local tire/brake place that I have a good bit of confidence. After driving the car, the guy says, "You gotta bad strut!" Called FCP. They sent me a new strut. I installed it and sent the other back. Sounded a LOT better—for about two weeks. Now I am hearing the sound on both sides. I took it to a very reputable Volvo mechanic, I have used since the warranty expired. He drove it, confirmed the sound was not normal. We put it on the lift and he checked everything on the front suspension and was stumped. He said there was nothing wrong with my installation, no problem with the suspension.
Okay, FCP has an unconditional satisfaction guarantee, so I could replace these with a more expensive strut for say $50 more, but is the problem with the struts? I would hate to have to do this installation again and still have the same problem.

I have a knock on the passenger side front of my 2001 passat 2.8L 5speed. It knocks whenever i give it gas, whether its while im letting the clutch out or not. It has been getting worse. At first i thought it could be a tranny mount but the one underneath the car on the passenger side looks perfectly fine.
View 4 RepliesLast night, I replaced both front struts with Monroe complete sets (new springs, mounts, boots, struts, etc) and I had my front rotors smoothed out. That cleared up about 75% of the noises coming from the front of my car Except for one.
Whenever I'm braking, there is a noise coming from my front left wheel. It's not a brake squeal, but more like a creaking sounds that comes around with each rotation of the wheel. It slows down with the car, and I can make it last longer by doing a slow roll with the brakes one. So when I'm fast it sounds like "Crk! Crk! Crk!" When I'm going slow it's "Creeeeeak... Creeeeeeak... Creeeeeak..."
Last night, I also replaced the sway bar link on that side. The brakes are smooth and the tires were balanced a couple months ago (no steering wobbles at any speed)
2006 x3 with 88k on it. I've read that this is a common problem, with the 4 x 4, brake light, and ABS light all coming on and a tap tap tap sound when you turn off the car. Sounds like it's the gear but I am not handy and I don't really feel like going down there and doing this.
The dealer will charge to replace the entire transfer case. Is this a big issue? Sometimes when I drive it feels like I can hear a sound coming from the bottom of the car that sounds like it's about to stall but it never does.
At 60mph and above there is an odd sound coming from the front of my wife's 2004 expo. Now I think its the half shaft bearing but I can't be certain. I took the tire off and nothing was obvious?
View 2 RepliesOver the past few weeks, I have noticed a clicking sound coming from the right rear brake when they are moderately applied when stopping. Doesnt seem to happen under light braking. I figured something in there must have gotten loose so I got to taking the drum off to inspect and clean the insides, or see if anything was broken. Everything seemed to be in order, inside of the drum looks fine as do the shoes, Nothing is really jumping out at me as a cause to this noise. I hit the brakes with the shop vac to suck out any brake dust I could get.
Then, with the drum off, I had my fiance apply the brakes a few times, and the parking brake, just so I could see if something in there was not operating as it should. Heh. I dont think you are supposed to do that with the drum off. The shoe adjuster fell off the shoes (#2 below) So I had to get that back in place and I am pretty sure I have it in right. I go to put the drum back on, and the pads are now too far apart and it wont go back on.
So, I decide to try opening the bleeder valve on the brake cylinder to see if I can get the pads to move in at all. it drips but I cant get the pads to budge. Then I shortened up the shoe adjuster all the way so I could get the drum back on.
Now my parking brake lever, I have to pull it waaay up to even get the parking brake to engage. I figure I have to go back and crank that adjuster out some so the shoes engage sooner. Also, I probably got air in the brake line when I opened the bleeder, so I have to bleed the brakes for real.
Over the past month or two, I've noticed a clunking sound coming from the front brakes when you apply the brakes. It seems to only happen when you're backing up and after the car has sat a while.
