yeah i mean not jacked up!

they hold the top of the shock in place, but the weight of the car will keep them in place!

ok, today I installed the strut. it went in without any problems exactly on the 4 bolts, but, now I'm unsure, do I need to tighten the nut holding 2 sides or not. I tried and it doesn't budge a mm. I even tried with the long steel bar I sticked on the cutted wrench (yeah, I destroyed one of the wrenches just for this ).

I tried goggling a bit and there are many opinions. Some say that it just needs to fit the 4 bolts after which you just tighten them and that's it. Some say you need to tighten the strut, and some even say you need to installed it when the car is jacked-up on the front.
cheers.

I dont think u need to do much. As long as its not loose mate. Its it slack, i would, but if it all seems nice a tight, then leave alone
