Not real clear that the new mounts are torn? Those ripples on the sides of the rubber are common. What would be a real concern is a tear through the soft black material.
The shaking side to side is either (1) a bit of crap got into an injector, or (2) you over adjusted the rack damber bolt. If the latter was the case, you will notice the engine will shake or will act up after running it up and letting off the throttle. If it is seriously over adjusted it will die with the same run up.
Maybe just follow up the work with a diesel purge session.
