Ok,

I ordered 4 brand new end links from topdownsolutions.com and I am wanting to know beforehand if there is anything critical that I need to know.

I know that the suspension needs to be loaded (Ramps)

I also need to know how tight they need to be during re-assembly, I have heard different things and I DO NOT want to mess this up.

Anything else?

 

Doesn't make the slightest difference whether the suspension is "loaded" or not.

It's beyond simple, really.... you just pop em in and tighten em. Stop when the bushings squeeze out to the same OD as the washers. I'm guessing these are poly; if so, it won't take very much more tightening past the point that all the slack is taken up. They're hard and don't deform much, and they're already nearly that large anyway.
