many many things, Loose lug nuts which lets wheel make knocking noise. Engine will make a knocking noise if it is really low on oil. Some timing belts make a knocking, slapping noise just before they break.These are just a few examples . Have someone ride in car with you as you duplcate the noise and see if they can determine which part of the vehicle it is coming from.

It's really hard to understand what you're asking here."What causes a knocking sound when your car drops into a hole while driving?"If that's your question, I imagine that it would be the sound of your car dropping into a hole.

Bad CV joint, loose rim, Loose caliper

The combination of fuel still being pumped into the engine and air

If it only happens when backing up, you may have the parking brake engaged.

Driving at 50mph or above what causes a loud knocking clicking sound during acceleration?

Check the drive axle for a broken and leaking boot or bad CV joint.

Mine did the same, mine was a motor mount.

Possible cam chain tensioner has broke.these tensioners are none adjustable and sometimes brake causing a knocking sound in the motor

Sounds like a piston hitting the cylinder head. A lifter will usually tick, but a piston will sound more like this knocking noise.

it could be your valves or your engine

If the brakes are too loose that could be a result.

Your rear tire could be making a knocking sound for a number of reasons. You could have a damaged strut or axle that needs replacing.?æ

A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.

Could be a rod knock. Your bearings slipping in the engine.

It's the spirit of the car knocking on the side saying "HELLO??? TAKE ME TO A MECHANIC!"

Probably you have a bad tie rod (maybe both). You can find it on eBay (around $50.00 L&R). Knocking when turning on front wheel drive is most likely the knuckle on the axle. Look at the rubber boot on the end and I will bet it is split.
