Do you mean the one nut on the top of the shock? There should be a sheet in the box that gives the torque settings. In my case, I didn't have to touch that nut at all. If you had to loosen this for some reason, just get it back to the torque specified on the sheet.
So where are you at with this? Do you have both sides installed now?
What apenland01 was suggesting is that you tighten everything things reasonably and then put the tire back on and put the truck back on the ground. Then use your torque wrench to tighten to the final torque settings. You can access the top nuts through the hood, but those can just be tightened as hand tight as you can reasonable get with your wrench. The rear top nuts are difficult to tighten after the tire is on. I think the swaybar links are tightened to 24lb, but most just compress the bushings to about the same diameter as the washers on either side.

You can also use your jack under the LCA and jack the assembly up until the top of the strut is flush and you start actually lifting the truck. Then you can tighten everything up. Make sure you don't accidentally lift your truck off of the jack stands if you do that. I like that method because you have better access with the tire off, though it wouldn't hurt to recheck your torque settings after the tire is on and the truck back on the ground.

No I was talking about the UCA bushings, there's two bolts on each side that allow the unit to "rotate' up and down slightly, from the videos I've seen, you keep these loose, install the UCA, put weight on the tire, and then torque them. They were too tight to loosen off the car, so I installed, loosened, put weight on and retorqued, which seemed to have no effect on anything. I haven't done anything with the top strut bolt, no death wish for me.
I understand torquing everything with full vehicle weight on.
I gave up last night with only the driver side installed. I'm in the process of emailing KYB o figure out the problem, they wanted pictures of everything and said it may have been assembled wrong at factory :thumbdwn:
I would be happy to post some pictures if I figure out how. But I'll try and describe it the best I can.
Picture the top 3 nuts on the strut, two of these are close together and one is a "loner", now picture the bottom of the strut that the big bolt goes through, one side is "extended" and longer than the other side, this long side should be lined up with the two bolts on top which are close together. Instead it is reverse, the long part of the bottom is facing the single lone bolt on top.
I can't get the bottom to fit the LCA, and because of this, I can't even get the top 3 bolts in
Thanks
EDIT: in other words, if the top strut mount was turned 180 degrees I think it would fit. Still waiting on a response from KYB but would this involve is of a spring compressed, disassembling the whole shock/strut, turning the mount and reassembling? I really don't want to this, nor do I want to wait for an exchange if that's what it comes to.
I assume I'd have to reinstall the stock strut on the drivers side to match the passenger
