Overview
The Omix-ADA 16523.55 is a front driver-side Dana 30 axle shaft assembly with 27 splines for 2007–2018 Jeep Wrangler (JK) models.
It is a genuine Dana Spicer preassembled inner and outer axle shaft assembly. It sits in the front left position of the Dana 30 JK front axle and has 27 splines, the same count as the passenger side assembly.
Because it is a complete preassembled shaft, it replaces the inner shaft and outer joint end in one step. It is the driver side part for the front left position. Anyone replacing both sides needs the passenger side assembly as well. Make sure your Jeep has a Dana 30 front axle and matches the year, model and trim before ordering.

Before you replace an axle shaft
A front axle shaft carries torque from the differential to the wheel hub, and it is loaded every time the Jeep accelerates, brakes or crawls over uneven ground. With a preassembled shaft, the inner splines, the shaft body and the outer joint arrive as one unit, so the fit between the splines and the differential side gear is the first thing to check. Wear often shows as clicking on tight turns, vibration under power or grease seeping from the boot at the outer joint.
Replacing a shaft usually means removing the hub nut, the knuckle bolts and the carrier connection, so plan for a full front-end job. Many owners replace the matching axle seal and check the hub bearing during the same work. Keep the axle nut torque and bolt sequence from the service manual close at hand.
- Check the spline count on the old shaft before ordering
- Inspect the outer boot for cracks or grease loss
- Replace the axle seal while the shaft is out
