I-CAR Just In Time: Axle Housing 2-Point, 3-Position Check
I-CAR · July 8, 2026
Summary
This I-CAR Just In Time article and video demonstrate how to perform a 2-point, 3-position check to diagnose damage in solid axle housings. Because solid axle housing damage can be difficult to detect visually, this specific diagnostic test helps technicians identify hidden structural issues in the suspension system.
What to do on the job
Perform a 2-point, 3-position diagnostic check on solid axle housings to identify hidden damage following a collision.
How to use it
Use this document and the referenced I-CAR 2-point, 3-position check procedure to justify the labor time required for diagnostic measuring of the rear axle housing on vehicles with solid axles. This is especially useful when defending a supplement for suspension/drivetrain diagnostic time where physical damage is suspected but not visually obvious.
