That Franklin tool I rented pulled the sub-frame mounts out easily and replacing with very little 'lube' was easy from an effort standpoint as well. Just took some time and cranking a wrench. I also R&R's the rear shock mounts at the same time. Even though most of the old sub-frame mounts looked good, the rear end felt better. The old shock mounts that I had not replaced with new shocks were noticeably compacted. Net net the ride is better after 500 miles.
