Why is there a clunking noise when I accelerate?
The most likely causes would be low transmission fluid, a shift solenoid, transmission mounts, or a drive shaft. Your best bet may be to have a qualified professional, such as one from YourMechanic, take a look at the car in person in order to diagnose and repair your acceleration issue.
Why do I hear a clunk when I brake?
A clunking noise when the brakes are used typically suggests wear and damage to various parts. It can be caused by a number of things from a seized brake caliper or an extremely loose wheel bearing to worn out ball joints or steering components.
Why Does My car clunk when I press the gas?
If the clunk happens when you hit the gas pedal or shift gears, then you are most likely looking at a U-joint or CV joint that is on its way out. An engine mount may also be the culprit if the sound happens when shifting into forward or reverse.
Why does my front end clunk when braking?
When you brake, it’s not just the brakes getting some action. The whole suspension gets weighted toward the front. If something suspension-wise is going bad, you can get clunking noises when you brake or when you first brake or first accelerate.
Can brake pads cause clunking noise?
Clunking Sound While Braking: Although rather rare, pads that are worn unevenly can cause a clunking noise while braking. The high and low spots of the pad surface bouncing up and down on the rotor cause this sound.
What is brake knock?
Brake knock off is when the piston has retracted further than needed (in my experience no more than 1mm on a road car – probably a lot less on a F1 car) and considering when you press the brakes they normally have to move less than 1mm to grip the disc, you have double the pedal travel to get the bite on the discs.
What does suspension clunking mean?
Something’s loose in your suspension. If you hear a clunk when the suspension works over bumps, you may have excessive clearance in a joint due to wear. It might be as simple as a loose nut on the strut, or something more subtle such as a shrunken, dried-out rubber bushing.
What does a leaking exhaust sound like?
If you have a faulty exhaust manifold gasket, it will cause an exhaust leak that sounds like a hissing or tapping sound. The sound is especially loud during a cold start or when you accelerate the vehicle.
What does bad muffler sound like?
The biggest and most noticeable sign of a bad muffler is the noise. When your muffler fails, the car will suddenly seem a lot louder than it did before. Be especially vigilant for any strange or sudden rattling noise, which could be the sound of a muffler that’s become loose or broken.
