Front Subframe: Service and Repair

Trustmark Authoring Standards (TAS) Repair Procedures

NOTE: TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.

A TAS removal and installation procedure uses a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.

Specification data
Specification procedures will only contain technical data that is not already part of a repair procedure.

Sequence of tasks
If components must be removed or installed in a specific sequence, the sequence will be identified numerically in a graphic and the corresponding text will be numbered accordingly.

Special Tools, Equipment, Materials and Torque Figures

Special tools will be shown with the tool numbers in the illustration. The special tool numbers, general equipment, materials and torque figures used for the procedure step will be shown in the text column.

TAS Graphics

Colors used in the graphic are as follows:
Blue - Component to be removed/installed or disassembled/assembled.
Green and Brown - Additional components that need to be removed/installed or disassembled/assembled prior to the target component.
Yellow - Component that is touched or affected in a way but remains in the vehicle. It may be detached, attached, moved, modified, checked, adjusted etc.
Magenta - Electrical connectors and fasteners such as nuts, bolts, clamps and clips.
Pale Blue - Special tool(s) and general equipment.










One illustration may have multiple steps assigned to it.

Numbered pointers are used to indicate the number of electrical connectors and fasteners such as nuts, bolts, clamps and clips.

Items in the illustration can be transparent or use cutouts to show hidden details.
