SERVICE SLEEVE ASSEMBLY
NOTE: Two sleeve halves are included with each
kit. Modifications as follow, are necessary to create
the correct sleeve assembly for each application.
(1) On 4X2 models, the9lower9sleeve is made by
cutting off the tab and cutting out a notch in the bot-
tom sleeve portion. Round the corners of the cut out
to keep stress cracks from forming. On 4X4 models
the9lower9sleeve is used as provided. (Fig. 15)
(2) On both 4X2 and 4X4 models cut off the front
tab on the upper sleeve portion. (Fig. 16)(3) The sleeve halves are shipped slightly over-
sized to allow custom fitting to each replacement
frame rail tip. It is necessary to grind the mating
surfaces to achieve the desired snug fit into the
replacement tip (rail tube has increasing height rear-
ward of the cut line). Once the two sleeve halves are
fitted, bevel the edges 25É - 30É.
NOTE: Scribing a line 2 mm from the cut edge and
then grinding back to the mark will simplify the
bevel creation process and accuracy.
(4) Remove any burrs at the beveled edges.
(5) Using the Weld Process Specifications table
(Refer to 13 - FRAME & BUMPERS/FRAME - SPEC-
IFICATIONS - WELDING), weld the two halves of
the repair sleeve together. (Fig. 17)
(6) Clean the welds of any flux and other impuri-
ties and grind smooth before proceeding with the
installation of the sleeve.
(7) Find the centerline of the sleeve and scribe a
centerline mark. Mark two additional lines 2 mm
(0.08 in.) on either side of the centerline mark to help
ensure the required 4 mm-6mm(0.16 in. - 0.24 in.)
weld root gap. (Fig. 17)

FENDER RAIL REPAIR
CAUTION: This repair procedure assumes damage
to the right or left hydroform fender rail (Fig. 18).
Prior to any repairs, the vehicle must be mounted

STANDARD PROCEDURE - HYDROFORM
FENDER RAIL REPAIR
CAUTION: This repair procedure assumes damage
to the right or left hydroform fender rail (Fig. 18).
Prior to any repairs, the vehicle must be mounted
on the appropriate frame repair equipment (ªframe
rackº), checked with three dimensional measuring
equipment, and necessary pull corrections made. If
damage exists in the hydroform fender rail, or cab
beyond the area covered by this service procedure
after dimensional corrections are made, the hydro-
form must be replaced in its entirety. Refer to 23 -
BODY/BODY STRUCTURE/WELD LOCATIONS -
SPECIFICATIONS, when replacing the entire hydro-
form.
(1) Before proceding with this repair procedure
review the required service warnings and precau-
tions. (Refer to 13 - FRAME & BUMPERS/FRAME -
WARNING)
(2) Disconnect and isolate the battery negative
cable.
(3) Remove the front wheelhouse splash shield.
(Refer to 23 - BODY/EXTERIOR/FRONT WHEEL-
HOUSE SPLASH SHIELD - REMOVAL)(4) Remove the fender. (Refer to 23 - BODY/EXTE-
RIOR/FRONT FENDER - REMOVAL)
(5) Remove the A/C condenser, if required. (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMB-
ING/A/C CONDENSER - REMOVAL)
(6) Remove the A/C lines, if required. Refer to the
Heating and Air Conditioning section of the manual
for recommended procedures.
(7) Remove the radiator assembly. (Refer to 7 -
COOLING/ENGINE/RADIATOR - REMOVAL)
(8) Remove the air cleaner and support bracket, if
required. (Refer to 9 - ENGINE/AIR INTAKE SYS-
TEM/AIR CLEANER ELEMENT - REMOVAL)
(9) Remove the integrated power module. (Refer to
8 - ELECTRICAL/POWER DISTRIBUTION/INTE-
GRATED POWER MODULE - REMOVAL)
(10) Remove the bolts and position aside the wire
harness and grounds, if required.
(11) Remove the upper radiator crossmember.
(Refer to 23 - BODY/EXTERIOR/UPPER RADIATOR
CROSSMEMBER - REMOVAL)

(14) Remove the bolts attaching the lower radiator
crossmember to the hydroform fender rail. (Fig. 18)
CAUTION: Do not use any flame or plasma cutting
equipment to cut the frame in this procedure. The
inaccurate and high temperatures achieved during
flame or plasma cutting will change the metal char-
acteristics and may weaken the frame and/or repair
location.
(15) Using a reciprocating saw or equivalent, cut
the fender rail and shotgun at a straight and square
section of the hydroform and remove.
(16) Smooth and square the cut edges.
(17) Using the damaged structure as a reference
cut the service part at the same location as the first
cut. Smooth and square the cut edges.
NOTE: The repair structure should butt up to the
remaining structure and provide the same overall
vehicle geometry.
(18) Fabricate 51 mm (2.0 in.) long repair inserts
using scrap from the old structure or the replacement
part. It will be necessary to split the inserts on each
of their four sides to fit into the hydroform.
(19) Remove any paint or e-coat from the inserts
and also to the interior and exterior of the hydro-
forms.
(20) Cut plug weld holes as described below.
²On the upper rail, cut one 13 mm (0.5 in.) hole
on each side of the rail, 25 mm (1.0 in.) from the butt
joint of the tubes.
²On the lower rail, cut one 13 mm (0.5 in.) hole
on the top and bottom sides of the rail 25 mm (1.0
in.) from the butt joint of the tube.
²On the lower rail, cut two 13 mm (0.5 in.) holes
on the inner and outer sides of the rail 25 mm (1.0
in.) from the butt joint of the tube.
CAUTION: Shield the surrounding area and compo-
nents from exposure to the welding spatter and
heat.
(21) Install the insert 1º into the replacement part
and tack into place with a weld. (Refer to 13 -
FRAME & BUMPERS/FRAME - SPECIFICATIONS -
WELDING)
(22) Insert the service part into place and using
the appropriate measuring equipment, verify the
front end sheet metal bracket's location in all three
(X,Y, and Z) planes of space. (Fig. 19)
(23) Complete all 360É plug welds.
NOTE: Before the final welding, use three dimen-
sional measuring equipment to ensure the part is in
the correct location. Verify that tap plate extrusion
at the bottom of the vertical post lines up with theisolator and hole in the frame perch mount. Also
ensure the lower radiator closure tube is bolted into
the forward shotgun ends.
(24) Complete welding by making a 360É butt weld
around the fender rails.
(25) Metal finish the exposed welds on the hydro-
forms.
(26) Dress the welded area and apply corrosion
resistant coatings inside and out.
(a) Inside the rail, inject a creeping wax based
rust inhibitor compound to the inside of the hydro-
forms ensuring 100% coverage including the mat-
ing face between the fender rail sections and insert
such that corrosion protection is restored in the
internal cavity.
(b) Apply a durable top coat to the outside of the
repair area.
(27) Install the front cab mount bolt if previously
removed and tighten to 81 N´m (60 ft. lbs.).
