Could be your brakes. If you have drum brakes not disk brakes that sound will happen when your shoes are worn down to the rivets. Some of the hardware such as springs, may have came off as well, which will make the loose metal sound.
Could be the brakes are metal to metal.
Check if muffler is loose, check if rear brakes are worn out & grinding
Your pads sound low-it's the wear indicators or you have metal-metal contact.
The grinding sound means that the brake pads are worn down to metal and that sound you hear is metal to metal. you need to have the pads changed, the problem is that you will more than likely have to change the rotors also. The way to avoid this in the future is when you notice your brakes are making a squealing sound that means that the pads will need to be changed soon.
The squealing sound you hear when your car brakes are wearing out is referred to as a "squealer." This indicator is a strip of metal that when the brake pad wears down makes contact with the rotor making a metal on metal noise.
Sounds like you need new brakes. When they get worn down they make a metal on metal sound.
The sound is most likely the brakes squealing. Check the pads to make sure that the metal part isn't cutting into the rotor.
You may need to check your brakes or the rollers on your brakes
Typical sound of Tin if a metal bar is bent. This screaming of Tin is coming from the friction/ shearing of the metal crystals.
A knocking sound while your car is moving is probably coming from the engine. A certified mechanic will be able to perform diagnostic testing.
Get your brakes tested. I do not know what a ticking sound means.
