Measuring rear track width, specifically the width of the rearend housing itself as described in the reference, involves using straight edges and measuring the distance between them.
The method described in the reference focuses on measuring the total width of the rearend housing, which is critical for determining compatibility with a vehicle chassis or understanding axle length requirements. This measurement differs from the distance between the outer edges of the tires or wheel hub faces, which are other ways "track width" is sometimes defined.
Here's how to perform the measurement based on the provided information:
- Position Straight Edges: Place a straight edge (like a long ruler, level, or metal bar) along the outermost edge of the rearend's flange on one side.
- Align Straight Edges: Place a second straight edge along the outermost edge of the flange on the other side. Ensure both straight edges are parallel to each other and perpendicular to the rearend housing.
- Measure the Distance: "Cross as straight as possible to the other side inside of straight edge." Using a tape measure or other suitable measuring tool, measure the distance between the inside edges of the two straight edges.
This distance represents the total width of the rearend housing, typically measured from the mounting surface of one axle flange to the mounting surface of the other.
Key Points for Accuracy:
- Ensure the straight edges are truly straight.
- Place the straight edges flush against the rearend flanges.
- Measure precisely between the inside faces of the straight edges.
- Measure multiple times to confirm accuracy.
Understanding this specific measurement helps ensure the rearend housing width is correct for your application, affecting wheel fitment and overall vehicle stance.
