Check for runout in your wheel bearing hubs. You can also hit your e brake lightly and see if it shakes then. If it does, it is in the rear rotors which will also warp.

Ck your exhaust pipe at rear of car noting any obnoxious smell like rottrn eggs. Hold a piece of paper, I use a dollar bill ,in in front of the exhaust. If it blows the paper gently, you have a catalyctic converter going or is bad. Will need replace if so.

you are apply torque to the engine upon pushing on the gas pedal so the law of nature states the engine mount maybe broken

You may want to check the water pump if it's overheating, have the motor mounts checked if the vehicle is shaking and the alignment and tire pressure are fine, first check the fuses for the interior lights. As for the clicking sound in front tires - please provide further explanation as to the sound, speed of vehicle when it happens, and mileage on the vehicle - could be the CV's but not enough information to assess.

Sounds like you have a broken belt in one of your rear tires, or a bent wheel. This would feel like the car is rocking a little bit like a boat on small waves. You can check this out by lifting the rear tires off the ground a slowly rotate them while looking at the tread, if you see the tire really wobble or have a bump in one spot that's it.
