Alignment Checking

Use a measuring tram gage in order to determine the alignment of the underbody. In order to perform the recommended measuring inspections, the tram gage set must include a vertical pointer capable of reaching 914 mm (36 in).

You may make the following measurements using a tram gage:

• 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-gage holes to the following areas:

• The leading edge or center of the holes
• The flush-to-adjacent surface metal

Refer to Dimensions - Body   in Collision Repair for the following information:

• The alphabetically identified points of measurement
• The metric-to-English dimensional conversion data
