Hello I will help you with your question,
You listed this as a 2006 Civic with a 1.4L Is this correct? Hybrid? 2 Door?
Let me know if you have questions
You will have to remove the wiper arms, you can use a battery terminal puller or a tie rod puller to get them off, the bushing does snap onto the motor link but you will have to remove the assembly to get the motor out. Use the puller to get the arms off, you can get either one at most parts stores.
The studs for the arms are slightly tapered and splined so they will be tight. If you are very careful you can put the nuts on a couple of threads and tap the nut as you pull the arm straight up but this is dangerous, I suggest the puller
