i just discovered that after a recent crash that i bent both of my shock shafts on one side. (they were bent bad enough where they wouldn't slide in our out. so i took the shaft out and bent them back and now the they seem to be working fine. what i need to know though is what kind of oil i need to replace the shocks with. they are not leaking so they are still good, it just dumped out when i took the shaft out. they are stock shocks.
