How do i know if i have compressed the spring enough?
And will the top bolt be eaqsier to un screw once the spring is compressed enough?

 

assuming you are taking the spring and shock appart, compress the spring enough that the spring will move up and down. then loosen the top nut. this way the shock top wont come blowing off at you with the spring behind it. will it be easier? maybe, maybe not.

ok i got thwe spring compressed enough but now the dame allen screw at the top wont ffing work the bolt and allen key keep moving what will happen if the allen key part is stripped.

 

if you can, put an alen wrench to hold the piston from turning and remove the nut

 

i stripped it a few minutes ago what should i do now

 

If you DO NOT need the shock again then just put some locking pliars onto the shaft and squeeze the **** out of it until you can turn the nut.

If you DO need the shock again then get some liquid wrench on it, wait 15 minutes and then take an impact wrench to it. Make sure you have a buddy hold the other end of the shock housing tightly. Note: DO NOT use the impact wrench to put the nut back on!

 

what if i dont have an impact wrench

cant i just cut a lil sli in it so i can udo it with a screw driver

 

yeah it'll work, but just be careful and if that nut's stuck on you may not be able to hold onto the screwdriver.

 

so is this the reason why they say lossen it a little when it's already on the car

 

Partially, the shaft will always rotate on its own whether on the car or not, but on the car it's at least stable. Just remember that if you do loosen it on the car JUST break the nut loose, don't unscrew it or you could do some real damage.

I've taken nuts off by having some of my buddies actually grab the shock shaft and hang on while I got it loose.

 

but how would they grab it if the spring is compressed and it covers the shock shaft
