Installing thrust arms not at ride height

I accidentally forgot to load my suspension when installing my thrust arms over the weekend. They're turner arms with upgraded bushings. Should I go back and un-torque everything, load the hub/rotor, then re-torque? I made sure not to tighten the bolt that goes through the bushing until the ball joint nut was tightened. Thanks.

Basically just using my low profile jack to lift up the rotor on one side at a time to ride height

Better to get on ramps, because it makes it simple BUT....

What upgraded bushing do you have? If it's the monoball upgraded ones, it doesn't matter (assuming that you did torque it to spec at some point). But generally speaking, if they are any sort of rubber/composite/etc, then you should probably retorque it loaded to prolong its life.

Yes they are the monoball bushings with the blue ring. Good to hear. I'll call turner to confirm, but thanks!
