I will utilize my other Instructable on how to do maintenance on your cars shocks so some of the steps will be the same.
You can find my other Instructable on shock maintenance HERE
The Stuff You Will Need:
-Shock oil ( I used 30wt)
-R/C Shocks (No duhhh =) )
Step 1: Taking apart your shock
Attach a peace of tissue paper to your pliers(see pic 3).
After grabbing the piston with the pliers remove the bottom connector.
When you have removed that remove the dampener.
Look at the fourth photo for more detail on what to remove.
Step 3: The messy part
Then remove the piston and wipe it clean.
Step 4: The hard part is done
Slide the fuel tubing on to the shaft of the piston then re insert the piston.
