LR UCA grease upper bushings?

Received LRs, is it necessary to install zert fittings for upper bushings?
If so how to get the bushings out? And will I need new bushings?

The boot on lower bearing is sealed has it been lubed? SPC tech help is off on sat.

Will set caster at +2 and camber all the way out in slot.

Install the lca first then the ball joint to arm?

Have watched SPCs video.

Will be cutting upper bolts and install new.

Have watched video of truck on lift and LCA removed bolts at bottom of spindle LCA swung down to remove struts. Is this acceptable if can get truck high enough from garage floor and also remove UCA at same time with the swaybar removed?

OME kit still not here.

Have done a lot of research on this on TW. It is an amazing forum.

Thank you for all the hard work found here and the many excellent answers.
