check CV joints
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.
it might be a bent piton rod if you or water or somthing into the engine
get the person out pf your trunk...lol
you could have a wire broke in the tire
It depends on a few variables...#1 - If it's more of a hard clicking sound while the wheel is turned it will most likely be a bad half shaft (drive shaft with 2 CV joints going from transmission to wheel.)#2 - If it is a very hard knocking while driving on a flat, even surface it may actually be loose lug nuts. Tighten them up and check for the noise again.#3 - If it happens when you hit small bumps and a lighter knocking sound, it could be either a bad shock/strut or loose brake pads. If it's a hollow knocking it is a bad shock/strut, if it's more of a rattling knock, it's loose brakepads.#4 - Also check your front end bushings. If the rubber bushings are rotted/gone it can cause a metal on metal knocking sound.
A knocking sound in your Chrysler 300M engine while driving could indicate several issues, including worn engine bearings, a faulty timing chain, or problems with the valves. It's important to check the oil level and quality, as low or dirty oil can cause engine noise. If the problem persists, it's advisable to have a professional mechanic diagnose the issue to prevent further damage. Ignoring the knocking could lead to more serious engine problems down the line.
tie rods
The knocking noise could be one of several things. The wheel bearing, a worn steering or suspension part, or road debris could be causing the noise.
The failure to step on the brake pedal or if manual the failure to step on the clutch The transmission or gearbox is not working properly
A knocking sound while your car is moving is probably coming from the engine. A certified mechanic will be able to perform diagnostic testing.
check CV joints, if bad replace shafts and joints assembly
If when you turn a corner the knocking noise gets louder and more pronounced, then you have defective CV joints. The fact that the boots have holes in them, would indicate that water and dust has been able to contact the joints. This will cause them to self-destruct. This can be very dangerous, and if one breaks while you are driving you may have an accident. Replace th CV joints and replace the boots covering them.
