CAUTION: Do not use any flame or plasma cutting equipment to cut the frame inthis procedure. The inac-
curate and high temperatures achieved during flame or plasma cutting willchange the metal characteristics
and may weaken the frame and/or repair location.
12. Carefully remove the H-section welds using a grinder or equivalent tool.
13. Remove the H-section and clean any remaining welds from the frame.
14. Trial fit the replacement part.
15. Remove all e-coat from within 25 mm (1.0 in.) of the weld area.
16. Using the appropriate measuring equipment, position the replacementpart and verify correct positioning in all
three (X,Y, and Z) planes of space. (Refer to 13 - FRAME & BUMPERS/FRAME - SPECIFICATIONS - FRAME
DIMENSIONS)
CAUTION: Shield the surrounding area and components from exposure to the welding spatter and heat.
17. Weld the replacement H-section into position. The welding should be performedinaskip(stitch)typemethod
to minimize the heat buildup followingI-CAR or the American Welding Society welding procedures and utilizing
the process specifications at the end of this section. (Refer to 13 - FRAME &BUMPERS/FRAME - SPECIFI-
CATIONS - WELDING)
18. Dress the welded area and apply corrosion resistant coatings inside and out.
a. Inside the rail, inject a creeping wax based rust inhibitor compound through the existing holes in the frame
ensuring 100% coverage including the mating face between the frame and replacement H-section.
b. Apply a durable top coat to the outside of the repair area.
19. Position the wiring harness back.
CAUTION: Inspect the tire winch assembly (1) for
damage. If any one or more of the following are
evident, replace the winch assembly.
Indications of cracked or bulging plastic.
Housing flanges are bent or cracked.
If winch was loose before repair.
If the rivet heads are separated from the hous-
inginanyway.
20. Install the spare tire winch (1) and install the bolts
(2).
21. Tightentheboltsto41Nꞏm(30ft.lbs.).
22. Install the spare tire winch tube (3) and install the
clip (2).
23. Install the spare tire.
CAUTION: Check operation of the spare tire winch
by manipulating it up and down. If the winch binds
or jambs, replace the winch assembly.

24. Lift the axle into position and install the rear
shackle bolts (6).
25. Tighten the bolts to 163 Nꞏm (120 ft. lbs.).
26. Install the lower shock absorber bolts (Refer to 2 -
SUSPENSION/REAR/SHOCK - INSTALLATION).
27. Install the trailer hitch (1) (Refer to 13 - FRAME &
BUMPERS/FRAME/TRAILER HITCH -
INSTALLATION).

28. Install the cargo box (1) (Refer to 23 - BODY/EX-
TERIOR/CARGO BOX - INSTALLATION).
29. Reconnect the battery negative cable.

*First choice - Gas Metal Arc Welding Process:Butt joints - apply two layers (passes) of weld metal. First pass
should only fill approximately1⁄2the thickness. Vertical position welds - maintain electrode wire at leading edge of
weld puddle while traveling down hill to produce maximum penetration intothe sleeve. These techniques work for
FCAW as well.
**E7018new electrodes may be exposed to the atmosphere for up to ten hours with no harmful effect.
Reconditioning schedules should come from the manufacturer.
FRAME DIMENSIONS
NOTE: Frame dimensions are listed in metric scale. All dimensions are fromcenter to center of Principal
Locating Point (PLP), or from center to center of PLP and fastener location.
VEHICLE PREPARATION
Position the vehicle on a level work surface. Using screw or bottle jacks, adjust the vehicle PLP heights to the
specified dimension above a level work surface. Vertical dimensions can be taken from the work surface to the
locations indicated were applicable.
