When shifting a manual (or standard) transmission on a vehicle, if you hear excessive knocking noises immediately after shifting, you are probably:
1) Shifting into the next highest gear too soon, or
2) Shifting into the wrong gear - for example, going from 2nd to 4th gear, or
3) Not running the engine fast enough after shifting to the next highest gear, or
4) Your engine is out of tune if you know you're doing steps 1,2 and 3 correctly
Typically, a knocking noise when to use your brakes in the car is caused by your brakes wearing down. This means you need to get them checked out and repaired.
you may have a rod knocking and you need to take it to a shop asap
You probably need your bearings repacked
Depends on where the noise is originating from, a suspension component, engine (top or bottom?), steering knocking when turning, going over bumps, etc. You need to provide more details before I can point you in the right direction.
It may need oil? Or motor needs rebuilt.
== == I do believe if you hear a knocking noise that your crank shaft could be failing. Which means you will need a new engine. Have it checked out. Replace the harmonic balancer they will make a bad knocking noise. When you start it and the oil light goes out and it knocks, this is what is wrong with it.
your shocks or your brake pads are probly loose. You need to check them out. If that's not it then take it to a mechanic.
possible bottom ball joint £17 with delivery on eBay you do not need to change then whole wishbone as i was told
You need to check the u joints at the front wheels.
you need to replace your cv shafts, they are going out.
my grand am had an engine knocking noise. it was the intake manifold gasket was going bad. it was leaking coolant into my oil. look at your oil to see if it is a white milky color. if it is then you need a new manifold gasket which sucks. it takes a long time to do by yourself. or you can take it to a place that charges you $1000 to do. but if you can. do it yourself
It sounds like your CV (Constant Velocity) joints are worn and need to be replaced
