Rear Shocks!!

Hey guys ... and gals

My rear shocks are awfully soft. I'v egot them set on the highest dampening level. One leaks oil. How can I rebuild them or squeeze more air in w/o leaking?

I don't believe that the stock shocks are rebuildable, at least not in the normal sense. If you are really determined you can probably find a way to do it, but I'd just get another pair of shocks
