I just did this on my 2.2D.

On the 84 you do not need to take out the wiper frame (although, if you did it would be easier).

Loosen the second firewall (there are some 8mm screws and you can move it out of the way a little bit. You can then remove the motor without much trouble.

I would also suggest that you spend a little more and get the one with the cages already mounted. I purchased just the motor and had a hard time making sure that the cages are in the right position. Also, the cages are hard to take off from the old motor and install on teh new motor. I finally got it to work, but it was not worth the money that I saved.
