easiest way to remove a shock is to start with the top. By doing
it this way, with the shock still bolted at the bottom, you don't
have to worry about holding it with one hand while you are working
on it with the other.
first thing in removing the old shock is to get the top nut off.
on a shock absorber, when you turn the nut with a wrench, the piston
shaft will also rotate. So you have to wrench off the nut, but
also keep the shaft from rotating or spinning.
this instance, I have used a pair of Vice-grip pliers, clamped on
the very end of the shock's shaft, to hold it while I use a wrench
to get the nut off. This is a good time to use some WD40 on the
threads to help the nut come off.
not to damage the threads to much with the Vice-grips. There will
be some, but as long as the nut will work itself off, you are ok.
using your wrench.
goal is to work the nut up high enough so you can reset the vice-grip
pliers BELOW the nut. (This
is shown in our next step).
