IT is your CV Joints which is making this noise.
Might be a cracked vacumn hose, there are plenty, and the age is about right for this to happen.
When you accelerate. you are putting presure on the main engine barrens. if they are going bad. You will hear this knocking sound. I don't know how many miles you have on this engine. But that's what it sounds like. But that's not all that can make this sound. You will have to tell more about it and when it started. Did it just start all at once? or did it start and then get louder?
could be your steering is messed up for the turning. but for the transmission you could have blown piston
when we accelerate vehicle the supply of fuel gets increased .. Then inside the combustion chamber all the charge can't burn in such case so phenomena of knocking takes place.. So the sound can be heared.
You need to get your car checked.
Either your mechanic does not speak English or does not know what is wrong.
probably a universal joint. Or a cv joint depending on what is applicable to your car
Woodpeckers are known for making a knocking sound, especially during the early morning or at night when they are more active. Their rhythmic tapping on trees or structures can be mistaken for repetitive knocking sounds.
Mine and everyone I have hears makes a knocking sound at idle, I wouldn't worry about it unless it does it through the whole rpm or is really lowed
more than likely a valve!
possibly a warped or cracked flywheel...i had a vehicle that was doing this once and i let it go until i went to accelerate to pass someone and that was all she wrote....flywheel broke into pieces...i would get this to a shop and looked at ASAP cause if the flywheel breaks you gonna be stuck
A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.
