Axle Checker

The Axle Checker by WEHRS MACHINE is a precision diagnostic tool built for mechanics and automotive enthusiasts who demand accuracy when inspecting axle runout, wear, and alignment. Whether you're diagnosing suspension issues, verifying axle straightness after a collision, or validating custom axle installations on performance builds, this tool eliminates guesswork and delivers repeatable measurements. If you're serious about vehicle diagnostics—from street performance cars to race-prepped machines—the Axle Checker ensures you catch problems before they become expensive failures.

This specialized checker is engineered to mount directly onto an axle shaft and measure radial runout with the precision required for high-performance applications where lateral play or bending can cause vibration, bearing wear, or catastrophic drivetrain failure. The compact, lightweight design—weighing just under 2 pounds—makes it portable enough for roadside diagnostics or shop floor use without sacrificing rigidity. Its extended reach (25.2 inches in overall length) accommodates full-length axle shafts typical of rear-end housings, while the narrow profile (1.9 inches) allows access in tight underbody spaces where conventional measuring devices won't fit.

Mechanics, restoration specialists, and drag racing teams rely on the Axle Checker to validate axle integrity before final assembly or after detecting driveline vibration during test drives. It's equally valuable when upgrading to performance axles, verifying aftermarket components meet OEM runout tolerances, or inspecting salvage yard cores before installation. This is not a luxury item—it's a time-saving diagnostic that pays for itself in labor costs saved by identifying bad axles before they're installed, and it's compatible with most rear-end housings and aftermarket axle designs found in street, strip, and off-road applications.
