FRONT FRAME RAIL TIP REPLACEMENT
| CAUTION | This procedure is designed to replace the front frame rail tips that have been damaged in the crush initiator zones. Prior to any cutting, the vehicle must be mounted on the appropriate frame repair equipment ("frame rack"), checked with three dimensional measuring equipment, and the necessary pull corrections made without the use of heat. See Frame and Bumpers/Frame - Specifications If damage remains in the frame beyond the area covered by this service part after the pull, the frame must be replaced in its entirety. If damage to the front body structure is evident, repair the Front End Sheet Metal (FESM) fender rails as necessary. Inspect all body mount bolts for damage and repair if necessary. Refer to Body/Exterior/ISOLATOR, Body - Removal |
| CAUTION | Inspect the tire winch assembly 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 housing in any way. |

- Disconnect and isolate the battery negative cable (4).
- Remove the front fender liner of the side being serviced. Refer to «Body/Exterior/SHIELD, Splash - Removal»(ref-352624-S15760575692010010600000) .
- Remove the front fascia support (4). See «Frame and Bumpers/Bumpers/BRACKET, Fascia Support - Removal»(ref-352663-S16178330142010010600000)
- Remove the washer bottle and coolant recover bottles, if required.
- Remove the radiator and lower radiator hose. Refer to «Cooling/Engine/RADIATOR, Engine Cooling - Removal»(ref-352638-S08636206802010010600000)
- Remove the sway bar mounting bracket bolts (1) and position the sway bar (2) out of the way.
- For left side frame rail tips, position the power steering hoses (2) and axle vent hose (1), out of the way.
- Remove the front structure mount bolt (3) to the Front End Sheet Metal (FESM) bracket and the lower bumper support nuts (1) attaching the tow hook (5), if equipped. CAUTION: Do not use any flame or plasma cutting equipment to cut the frame in the next step. This is due to the inaccurate nature of the cut-line and the fact that the high temperatures achieved during the flame or plasma cutting will change the metal characteristics and may weaken the frame and/or repair location. NOTE: Durango shown in illustration, Dakota similar.
- Using a reciprocating saw (2) or equivalent, carefully cut and remove the damaged frame rail tip behind the stop bracket (1).
- Remove the three puddle welds attaching the remaining frame tip section (2) to the frame (1) at the locations indicated. (Right side shown in illustration, left side similar.) NOTE: Durango shown in illustration, Dakota similar.
- Remove the welds (4) by cutting along the outside edge of the weld (1) approximately 1/8 in. (2) using a plasma cutter or drilling out and then using a grinder to remove the welds. CAUTION: Oxyacetylene cutting torches or equivalent flame sources should never be used for cutting or welding. Only non-flame cutting methods should be used unless specified otherwise. NOTE: Durango shown in illustration, Dakota similar.
- With the puddle welds (1) removed, remove the remaining piece of the frame tip (2) from within the frame rail and discard.
- Smooth and square the cut edges of the original frame.
- Remove any burrs at the holes (1) and frame edges. NOTE: Durango shown in illustration, Dakota similar.
- Dry fit the new rail (2) to verify alignment, fit and make any adjustments as necessary.
- Remove all internal and external OEM e-coat within 25 mm (1.0 in.) of the weld joint on the replacement tip and the existing frame rail. NOTE: Any burned surface coatings will need to be removed prior to application of corrosion preventative coatings. CAUTION: Shield the surrounding area and components from exposure to the welding spatter and heat.
- Loosely install the lower FESM insulator and front structure mounting bolt (3). NOTE: Durango shown in illustration, Dakota similar.
- Position the stop bracket (2) against the frame rail (1).
- Using the appropriate measuring equipment, verify the front end sheet metal bracket's location in all three (X,Y, and Z) planes of space, and adjust if required. See «Frame and Bumpers/Frame - Specifications»(ref-352663-S10509370902010010600000) CAUTION: Shield the surrounding area and components from exposure to the welding spatter and heat. NOTE: Durango shown in illustration, Dakota similar.
- When correctly fitted, tack the three upper ring fillet welds (1) to hold the tip (3) in position, then complete the ring fillet welds (1). NOTE: Ring-fillet welds may be filled in with weld material if an improved cosmetic appearance is desired.
- Confirm alignment of the replacement frame rail tip.
- Final welding should be performed in a skip (stitch) type method to minimize the heat buildup and frame distortion, utilizing the Weld Process Specifications at the end of this Service Information . The preferred method is GMAW (MIG). See «Frame and Bumpers/Frame - Specifications»(ref-352663-S10509370902010010600000) Apply root pass welds to the root joint (5) behind the stop bracket (2), one quadrant at a time, switching to the opposite side of the frame for each quadrant. Apply root pass welds to the root joint in front (4) of the stop bracket (2), one quadrant at a time, switching to the opposite side of the frame for each quadrant. Clean the welds of any flux and other impurities before proceeding with the cover pass welds. Apply the cover pass welds in the same manner as described above.
- Confirm alignment of the replacement frame rail tip. NOTE: Any burned surface coatings will need to be removed prior to application of corrosion preventative coatings.
- Dress the welded area and apply corrosion resistant coatings inside and out. Apply etch-primer to the inside of the frame rail repair area. Inside the rail, inject a creeping wax based rust inhibitor compound through the existing holes in the frame ensuring 100% coverage including the space between the original frame rail and the reinforcing sleeve. Apply a durable top coat to the outside of the repair area.
