AC compressor put load on engine causing engine shake vibrate.but check make sure AC compressor mounting bolts tight and drive belt correct tension.now if AC compressor very old most time bad compressor cause more load on engine causing shaking real bad.
If you have a vibration and you have eliminated the suspension and steering take a close look at the tyres. Look for bulges on the side walls , raised section of treads. Have the tyres rebalanced. Tyres are prone to belt seperation which causes vibrations
its possible it may be a bad inner cv joint as these can cause a shake when they start to seize and do not move freely.check to make sure that the wheel nuts are not loose and the front wheel bearings are not worn out and have excessive play in them,as if they do it can cause a vibration as well.
does the shake come and go at different speeds? check your tie rod ends by lifting the front wheels off the ground and grab the tire and shake from left to right. if they are tight you probbably need to replace the rotors
Could be a number of things from ball joints to your pitman arm(arm that steers the tires). It dont sound like tire are way out of balance because yu said it only starts when you hit a bump. If it was me, Id crawl under the front end and start shaking different parts until I figured out what was loose. if its shaking that bad you should definitly be able to tell when you shake it.
