A trailer jack 10 having two configurations for raising either a single axle trailer or a multi (dual) axle trailer (or other vehicle) comprising: axle engagement means 22; wheel transit surface 18; and peripheral ground engaging surface 20. Jack 10 is configurable between a first and second configuration. In the first (figure.5), the jack 10 is arranged to engage with the sole axle 62 of a single axle trailer. The jack 10 raises the axle 62 directly such that a wheel 60,61 can be removed and replaced. The elevating of the trailer jack 10 to the raised position is achieved through the movement of the trailer. In the second configuration (figure.3), the jack 10 is arranged to directly raise and support a wheel 60 mounted on one axle of a multi-axle trailer. The jack 10 effectively provides a small ramp 18 up which a wheel of the trailer can be moved / driven. There may be a stabilising means, which may be detachable 30 or articulated (130, fig.7) from the main body of the jack.
