can you have too much torque?

Ive been having many problems on both my Haro f3 and my DK General lee. My freewheels are breaking on both of them. I usually bike for 2 miles twice a day. i like going fast and for a long time ive been wondering if im using too much torque or just landing too hard off jumps. can ya help me? my freewheel brands are haro 16t and an integral 13t my gear ratios are 44/16 and 33/13 there are no hills around me
