The balancer is made of two pieces of still that are pressed together with a solid
piece of rubber between them. The most common problem is the rubber starts
coming apart. and the outside of balancer spins on the end side part,and wobbles.
Replace balancer
YES it can, but the engine would vibrate and shake if it did.
yes
warped rotor
I would contact the local parts store and replace the harmonic balancer if you think it is bad. a bad balancer can cause failure in the crankshaft bearings because of the shake.
Tires and wheels out of balance. Bad u-joint in the driveshaft.
Bad CV joint. Bent rim. Needs alignment. anything relating to your wheels could be the cause.
Yes, either can cause a shake while driving.
Hard to say. However, if the "rubber gasket" you're talking about is the center bushing on your harmonic balancer, that could throw your Harmonic balancer out of balance. This could easily make it shake to beat the band which in turn could be the knocking noise you're hearing. I suggest you get it looked at immediatly. If that is what happened, your engine won't survive long.
Wheel balance, bent rim, bad tire or worn steering components to name a few.
Fear can cause your poodle to shake intermittently. Even something as every day as taking a bath can cause a dog to shake if they are afraid of the water. Being happy could also cause a dog to shake, as could being sick or feeling pain.
a bad bearing will cause it to shake, also a rotar or shocks will do the same.
Most definitely. Any miss will cause the engine to shake. A vacuum leak will also cause this.
