Rebuilding/Refilling the Shocks
Step 1
After removing the shock,
push up on the lower spring
cup and remove it from the
shaft. Remove the spring and
preload spacers.
Step 2
Turn the shock upside down
and remove the black shock
cartridge/shaft assembly
from the shock body by
turning it counterclockwise.
Note
: If you only wish to
change or fill the shock fluid,
skip to step 5.
Step 3
Remove the top E-clip from the
shock shaft. Remove the shock
piston. Remove second E-clip.
Remove the old cartridge.
Put a drop of oil on the shock
shaft before installing a new shock
cartridge.
Step 4
Reinstall the lower E-clip.
Slide the shock piston onto
the shock shaft against the
E-clip. Reinstall the top E-clip.
Step 5
If you plan on completely
changing the shock fluid
(suggested), dump out the
old fluid from the shock bod
y.
Carefully fill the shock body
with fluid to the bottom of the
threads inside the shock bod
y.
Step 6
Pull the shaft out so the
piston is next to the
cartridge and reinstall the
assembly into the shock
body. Turn in a clockwise
direction until snug—DO NOT
TIGHTEN yet!
Step 7
Turn the shock over and use a #0 Phillips
screwdriver to remove the small bleed
screw at the top of the shock. Slowly push
the shock shaft up until it stops. Excess fluid
should flow out of the bleed hole. Slowly pull
the shock shaft halfway back and replace
the bleed screw. Use pliers to tighten the
cartridge, being careful not to strip the
plastic lobes on the cartridge.
Step 8
Replace the spring and
spring cup and test the shock
action for smoothness and
leaks. Retighten the bleed
screw or cartridge if either
leaks. Remount the shock on
your truck.
Note: Production shocks may differ slightly from those shown
in the drawings.
