While we're working on the detailed instructions,
here's some tips on installing your APEX truss. Refer to online pictures for
orientation of the truss.
Installing this product requires Welding and Fabrication skills, If you
are not confident in your abilities to complete this task please have this
installed at an qualified off-road shop .
Inventory all parts to ensure you have all of the correct
pieces. If you
are missing parts Contact Artec Industries Immediately at (855) 278-3299 M-F 8:30-5pm MST If outside of those hours

label on box as well as your invoice number
Per our Shipping service if box is damaged Keep all packaging if box is
damaged aswell as photograph the box to ensure any shipping claims can be
Unpack contents of shipment. Remove axle from vehicle for
best results and easiest installation. Prior to mockup make sure axle is clean
and uninstall any oem and aftermarket bolt-on accessories that may conflict
with truss installation. Remove axle breather hose and uninstall any electric
locker wires from casting. This area will be welded so care should be taken to
prevent these components for melting.
Using a marker or paint pen, indicate the areas on the axle
where the truss touches the axle to prepare for welding. Remove truss pieces
from axle. Using an angle grinder with either a flapper disc or wire wheel
brush, clean the surface of the axle tube, casting, upper control arm mount,
and coil perch until bare steel is exposed. Clean surfaces on drivers side
casting, tube, and coil perch in a similar fashion. Repeat step 2 and place all
truss pieces back on axle.
Prior to welding, ensure that the bottoms of all the truss
pieces are in a straight line all together. The long truss can sag a little
near the UCA mount so push down on the part over the casting and it'll
straighten out. Place tack weld on truss pieces to hold all in place. Double
check all truss pieces are straight.
Begin welding small strips of truss that touch the axle
tube. You want to move around to different parts of the axle as you weld so you
don't heat up areas too much. Place a welding blanket over welds so they do not
cool too quickly.
To weld truss to cast section with best results, preheat
casting evenly around where truss contacts to approximately 400 degrees. DO NOT
HEAT UNTIL GLOWING RED AS THIS MAY DAMAGE THE CASTING. Once preheated, weld
truss to casting before it cools. For best results, use a needle scaler or
peening hammer to relieve the weld directly after welding. Post heat the area
to approximately the same temp you used to preheat. Wrap axle in a welding
blanket to slow the cooling process, the cooling should be slow (18-24hrs.) and
uniform. (The idea behind this method is to relieve the stresses in the
materials prior to welding, and ensure that the plate steel does not cool
quicker than the cast resulting in stress cracks.)
When completely cooled, check for any cracks in weld
especially around the casting. If cracks are discovered repeat the necessary
steps above, grinding out any cracked welds and prepping the area.
Remove the hub/axle
shaft from Jeep as a unit With the hubs
and axle shafts removed stuff some rags in axle tubes.
Remove the knuckles
from the Vehicle . Now Remove your ball
joints from the axle the Heat caused by welding the C gussets can damage the ball
joints. Once the ball joints are removed
weld the C gussets into place (The JL4405-3 is Driver
Upper JL4501 is Passenger side
upper The JL4505-2 is driver side lower
and Jl4405-4 is passenger side lower)
Then wrap in a blanket to cool slowly
Once the C's are cool you can Install the ball joints we suggest
freezing them before you install and apply a thin layer of grease to help
install them Once the Ball joints are
installed install the knuckles onto the axle and Remove the rags from the axle
tubes . Place some grease on the
splines of the axle shafts an carefully
slip the axle shafts and unit bearings into place . all of the knuckle and hub
bolts to factory specs.
(Make sure you support the axle
shaft as it passes into the housing and do not force it into place this could
risk damaging the axle seals )
Use a grinder or wire wheel to clean the surface of the LCA
mounts to remove any paint, rust, or debris to ensure it is ready for welding .
Place the Control arm skids on the LCA bracket and weld them
into place .Weld the open seam on the
LCA skid and leave the little round holes open for Mud and water to drain from.
Once axle is ready, paint truss and axle where bare steel is
exposed to prevent rusting. After paint is dry, reinstall axle breather hose,
electric locker wire, and any other components. Install axle according to
