My car started shaking and has gotten worse. It is not bad in the idle position, but when I put it in drive it starts a slow deep shake that gets faster and harder as I increase speed. Also, in reverse, my steering is very hard to turn, which began recently with this other problem. I was told my front motor mount is the problem?

1991 Nissan Maxima Question: How do I know if a motor mount is my only problem?
although anything is possible, motor mounts almost always cause vibration at idle(in drive or reverse) and are almost unnoticeable at a steady cruise. sounds a bit more like either a misfire or something out of balance or loose. i would highly doubt a motor mount will solve your problem. as for the hard steering in reverse they could be related but in the absence of any noise when in reverse i would think it would be a separate problem.
