Use a measuring tram gauge in order to determine
the alignment of the underbody. In order to perform the recommended measuring
inspections, the tram gauge set must include a vertical pointer capable
of reaching 914 mm (36 in).
You may make the following measurements using a tram gauge:
| • | Direct point-to-point measurements |
| • | Measurements you calculate on a horizontal plane (datum line)
parallel to the underbody |
| | For each point to be measured, set one of the following pointers as
specified: |
Take the point-to-point measurements from the following components:
| • | The front structure steering component |
| • | The suspension component |
Ensure that the vertical pointers are equally set.
In some cases, you may directly take point-to-point measurements using
one of the following tools:
| • | An appropriate measuring tool |
Measure the dimensions-to-gauge holes to the following areas:
| • | The leading edge or center of the holes |
| • | The flush-to-adjacent surface metal |
Refer to Underbody Dimensions for the following information:
| • | The alphabetically identified points of measurement |
| • | The metric-to-English dimensional conversion data |
