Apparatus for aligning trailer axles without removing the wheels on the axles comprising a mounting that fits on the wheel hub cap and extends from the hub cap so that its outer end forms an unobstructed line with the trailer king pin. The outer end of each mounting has a rotatable tape mount for accommodating a measuring tape. The front trailer axle is aligned by measuring and equalizing the distance from the king pin to each outer end of the mountings on the front wheels. The aligned front axle comprises a reference line for aligning the rear axle.
