Likely a loose or broken strut or shock. Could be the same for a load leveling bar, depending on the vehicle.
low gas, flat tire, broken gas
A leaking manifold seal on the intake will cause a popping noise on the 1996 Honda Accord. This can heard most clearly on days when the weather is cold because the seals tend to shrink.
If it pops when turning it is most likely the CV joints.
You may very likely have bent the thin metal backing plate behind the brake rotor. That will cause the backing plate to rub against the rotor and make an awful grinding noise. Its not too hard to reform the backing plate away from the rotor.
== == Could be the transmission, or a front brake is sticking on.
metal, right? Sounds like metal, yes.
Could be a bad CV joint. It would make a popping noise.
DID you check for a air leak,fuel,ok. Carburator?
I would like to know. I have had a popping noise in my throat for about a year now. My doctor says it's harmless and normal since there is cartilage and bone moving in that area of the throat.
check the U-joints in the drive line
When mine did that popping noise it was the fuel pump. But it could be a number of things. It depends on exactly what kind of popping. The Chevrolet Blazer wasn't the best of the bunch. They do really well as trucks. But the maintenance is that of a Toyota.
