Full Frame and Body Mounting: Other Ford Ranger II

Welding Precautions

1. If welding must be done on a frame, make sure the following requirements are met: If the frame is attached to the vehicle, the battery ground cable must be disconnected before using any electrical welding equipment. For additional information, refer to «BATTERY, MOUNTING AND CABLES»(ref-268774) . Do not use gas welding equipment. Use a temperature-indicating crayon to make sure that the temperature does not exceed 750°C (1,400°F). Install new spot-welded components by spot welding where possible. If spot welding is not possible, use puddle welding.

Frame Straightening

1. When straightening the frame, make sure the following requirements are met: CAUTION: Reposition and/or shield any fuel lines, brake lines or wiring harness or component in the heated area. If heat is needed to straighten a frame member, keep the temperature below 650° C (1,200° F) (a dull red glow). A temperature sensitive thermal melt crayon should be used to monitor heat buildup. Heat should be kept to a minimum area so that the hardness of the metal will not be affected. Straightening should only be attempted on frames that fail to meet specifications of the diagonal checking method or where damage is apparent. Straightening should be limited to parts which are not severely bent. Reposition and/or shield any fuel lines, brake lines, or wiring harnesses or components in heated area.

Frame Reinforcement

Note. The frame must be straightened before any reinforcing can be started.

Scheme 20

1. After a bent frame member has been straightened, inspect the frame member closely for cracks. If any cracks show, the frame member should be reinforced or replaced. Reinforcements should be made from angle or flat stock of the same material and thickness as the frame member being reinforced, and should extend to either side of the crack. Ideally, the reinforcement should be cut from the corresponding area of a similar frame.

Body Misalignment Check

1. To align or square a body, take 2 opposite diagonal measurements between pillars. Take measurements between reference points such as crease lines or weld joints that are diagonally opposite each other on the 2 pillars being measured.
2. When repairing a vehicle with damage on both sides, take horizontal and vertical measurements from a vehicle of the same body style and transfer the dimensions to the damaged vehicle. Alignment can be made by diagonal measurements taken from points on the 2 pillars.

Scheme 32

1. The dimensions of the underbody must be restored if repairing major body damage to provide correct front and rear wheel geometry. Once the frame and suspension members are aligned, other operations can be carried out.

Scheme 33

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to «JACKING AND LIFTING»(ref-268709) .
2. Remove the 2 transmission mount nuts from the transmission support crossmember. To install, tighten to 90 N.m (66 lb-ft).
3. Support the transmission with a suitable jack.
4. Remove the transmission support crossmember. Remove the 2 horizontal transmission support crossmember bolts and nuts (1 each side). To install, tighten to 127 Nm (94 lb-ft). Remove the 4 vertical transmission support crossmember bolts and nuts (2 each side). To install, tighten to 99 Nm (73 lb-ft). Remove the transmission support crossmember.
5. To install, reverse the removal procedure.
