For 1990-2009 cars

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:

- | The height pointer

- | The vertical pointer

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:

• | A tape measure

• | 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
