Sound not loud enough to hear indicators - Cars & Trucks

If you are hearing a loud "Clicking" noise when you turn the key it usually means the battery has some power but not enough cranking amps to start the car. Get a battery charger on it or take it somewhere and have the battery tested.

Noise usually indicates worn part. Lubricating it can help, but it won't solve the problem. Once a bearing starts to wear, it develops a flat spot on the bearing. If the wear is significant, rotating the tires individually off the ground will sometimes be enough to indicate if it's the wheel bearing ( you can hear/feel it at only one tire ) or a differential bearing ( you can hear/feel it on both sides of the same axel )

A bearing in the transmission or the transfer case will sound central to the vehicle...much easier to identify if a passenger in the vehicle can try to pinpoint the sound while the vehicle is being driven by someone else.

When fuel level is very low, it can be noticeably heard. A full tank will dampen the sound. If anything you should hear a light hum. If its noticeably loud, then its an indication that it may fail soon.

Not much we can do without knowing where the noise is coming from. It could be something rubbing because the engine is shifting. It could be moving around when in drive such as a weak motor mount. Or the crankshaft could be moving under load.
You may need to have a friend watch the engine from the side to see if anything is changing when you go from park to drive. You can also use a section of hose as a hearing device to pinpoint where the sound is coming from.

your fan may be running all the time, or possibly a vacuum leak but if it were one loud enough to hear you car would be running rough.

Sounds like a battery problem. The clicking sound is usually the starter solenoid trying to engage the starter but not enough voltage or amps. There has to be enough power or you will not be able to move shifter assuming you pushed the brake pedal down while trying to shift out of park. And, it hasn't been noted whether it is a manual or auto trans.

how does the trans fluid look?at proper level?it sounds like the front pump in trans is starving for fluid..filter may be plugged..does it shift ok?any fault codes?i would check these things and probably drop trans pan to see if any debris/dirt/metal in pan indicating an internal problem..i hope this helps

It sounds like the power steering belt is too loose, tighten it up a bit but not too much just enough to make slipping belt stop.

you need to replace you brake pads. and probably your rotors if you let it get bad enough to be metal on metal.

sounds like a wheel bearing,ask a local mechanic to confirm
