Is this coming from the engine? If it is it sounds like you might have some lifter problems. Or the worse part is if you have a rod knocking. Intrepids did have some egine problems.
It is sometimes referred to as Hand Tapping.
the first lifter facing on the letf makes a tapping sound sometimes
wheel bearing
because you suck at driving it
It does not necesarily mean you are insane. Sometimes, noises around your house can resemble the sound of the door being knocked. At other times, immature children - or even immature adults - may knock on the door, and simply run off, just for a laugh. Sometimes, if you have a habit of tapping without realizing it, you may end up tapping on a wood surface, and think it was the door, not realizing it was you.
It might be the CV joints. Go to a front suspension specialist and have it checked out.
Sometimes putting a jug of transmission fluid in your oil will clean the junk out of your lifters and stop your noise - if it is an older vehicle with adjustable rockers you can adjust and get rid of the knock.
The Bendix is stuck, need new starter. Sometimes tapping on the housing with a small hammer will release it, but temporary only. <><><><><> Is it possible that the jump starting fried the computer???
A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".
If the bolts have been removed and the wires disconnected, try tapping the starter with a wooden block to loosen it, Sometimes the starter will stick in place due to sludge and grime.
It means your sulinoid is bad. Is part is sometimes built in the starter or separate under the hood. Likely under the hood, mounted to the passenger side wheel well somewhere. Sometimes it will do this because of corrosion on the battery. Or a bad starter. You can try tapping the sulinoid or starter temporarily but it won't work for long.
Possibly a failed door actuator in the ac system. There are three actuators in the dash, could be either.
