STEP 1
Open the bumper and loosen
the 4 bolts shown in the image
on the right. These 4 bolts are
located on the inside of the
bumper channel — 4 on each
side — and should be loosened
just until the washers spin freely.
STEP 2
Close the bumper to make the
next adjustment.
STEP 3
Standing in front of the bumper
tighten the 2 adjustment bolts
until rattling stops and the Slam
Latch Handle feels secure.
These two (2) bolts are located
on the back of the top fold of
the aluminum bumper channel.
(One is on the driver’s side and
one is on passenger’s side.)
STEP 4
Open the bumper and tighten
the 8 bolts (4 on each side). If
handle feels secure and latches
properly, the adjustment is
complete. If the Slam Latch
handle is too tight, loosen the
adjustment bolts and start
again at STEP 1.
