I just replaced the swing arm bearings.

You need to loosen the linkage that goes from the frame to the rocker arm and then to the motor swing arm bolt. Use lots of penetrating oil and have patience. Also, leave the nut on the end of the swing arm bolt. Thread it to the end and just pass the bolt end. This protects the threads and gives you a surface to use a dead blow hammer on. You don't want to damage the threads on the bolt.
