My 93 chevy cavalier sounds like metal is hitting when i start it it and when im driving

The speedometer cable should not have anything to do with changing the ball joint. it goes directly to the transmission on a 93. your grinding sounds like either someone didn't get the bearing back in the hub right or loose bolts on the wheel ..

CHECK STARTER AND FLYWHEEL ONE OR BOTH SOUND LOOSE

It sounds like you have a bad vaccum leak around your fuel system or intake. Could also be a weak fuel pump or clogged fuel filter.

well cavaliers are known for bad exhaust my guess would be the exhaust manifold gasket is bad.

For the 1993 Chevy Cavalier 2.2L:

Where exactly does it sound like it's comeing from?

1.The shims go between the starter body, and the engine block. These are installed to space the starter drive gear, away from the flywheel. They are only used if needed.

2.There is a gap that you need between the starter gear teeth, and the flywheel teeth. This gap should be about 3/32nd's of an inch, to 1/8th of an inch. With a flashlight, and a ruler, measure between the outside edge of the starter drive gear teeth, and the outside edge of the flywheel teeth.

Too close, when starting the vehicle it sounds very metallic, and like you're grinding corn.
Too far away, and the teeth don't engage properly, and you'll KNOW it! Sounds like a metallic 'zing', as the teeth skip. (Also it won't be long, and you'll be replacing the starter drive, and the flywheel!)

You need to pin down where the noise is coming from. It sounds like a pump, but cant be sure.

look at your trany and right below your air filter box is an 4 pin plug. unplug it and then see if the problem still there. I had the same problem with my 93 cav. and I posted today (2/8) and micheal helped me and it worked

sounds like you left something out. check to see if you plugged in all the sensors and plugs, then check for any vacuum lines that were not replaced or may have been broken
