29. Working on the driver side and using the new extended
radius arm bracket as a guide, carefully drill (4) 1/2” hole into
the frame rail. Special note: there will be (2) holes on the
side of the frame rail and (2) on the bottom of the frame
rail. Also, take special care not to drill into any wires or
hoses that could be running down the inside of the stock
frame rail. Repeat procedure on the passenger side. This
photo is showing the driver side extended radius arm
relocation bracket.
30. Locate (8) 1/2” x 1 1/2” bolts, (16) 7/16” USS flat wash-
ers and (8) 1/2” unitorque nuts from hardware bag
F4XRBNB. Also, locate the stock transfer case cross mem-
ber nuts that were removed. Working on the driver side,
secure the new driver side extended radius arm relocation
bracket to the stock frame rail using the new 1/2” x 1 1/2”
bolts and hardware. Make sure to use thread locker or loctite
and torque to 75 ft lbs. Now install the stock transfer case
cross member nut into the stock location. Make sure to use
thread locker or loctite and torque to 55 ft lbs. These pho-
tos are showing the driver side extended radius arm
relocation bracket. Repeat procedure on the passenger
side.
31. Locate the new driver and passenger side extended
radius arms. Locate (2) sert fittings from hardware bag
F4XRB-NB1. Install the new sert fittings into the eyelet ends
of the new extended radius arms. Take special care not to
damage the sert fitting during installation.
32. Locate (4) PB2408 poly bushings, (2) S10081 sleeves
from hardware bag F4XRB-NB1. Install the bushings and
sleeves into the eyelet ends of the new extended radius
arms. Special note: Make sure to use a lithium or moly
base grease prior to inserting the bushings and sleeves
into the new extended radius arms. This will help
increase the life of the bushings as well as prevent
squeaking.
33. Locate the stock lower shock bracket and hardware.
Also, locate the top stock bolt that connected the stock
radius arm to the stock front twin eye beam axle. Working on
the driver side, install the new driver side radius arm to the
stock front twin eye beam using the lower shock bracket and
the stock hardware. Make sure to use some thread locker or
loctite. Torque the top stock bolt to 145 ft lbs. and the shock
bracket hardware to 45 ft lbs. Special note: A good way to
tell the difference between the new driver and passen-
ger side extended radius arms is when they are
installed, they will angle towards the center of the vehi-
cle then out to the new extended radius arm relocation
