Overview
The G2 Dana 30 JK 27 spline front chromoly axle kit, part number 98-2050-001, is a front axle kit for non Rubicon 2007-2009 Jeep Wrangler JK models.
G2 forges these shafts from 4340 chrome nickel alloy, also called chromoly, and adds material in the yoke area around the u-joint cap to prevent distortion that can damage bearings. The shafts are machined for full circle snap rings and use a 5-760X joint.
Key features
- Forged 4340 chromoly alloy shafts
- Extra yoke material around the u-joint cap
- Machined for full circle snap rings
- 27 spline shafts
- Uses 5-760X joint
Dana 30 shaft considerations
Front axle shafts carry torque from the differential to the hubs, and they take hard loads on rocky trails, during hard braking and on uneven pavement. A shaft that uses full circle snap rings depends on those rings and their grooves to stay in position, so the retention hardware deserves a look every time the axle is opened. Shaft wear often shows up as clunking on turns, vibration that climbs with speed, or grease leaking from the seal area.
Because a 27 spline shaft only works with a matching differential, buyers should check spline count and differential type before purchase. Bearings, seals and the axle housing are usually inspected during the same job, since removing the shafts exposes them. Replacing worn seals while the axle is apart prevents a second teardown later, and cleaning the housing helps the new parts seat correctly.
- Count the splines on the differential side
- Inspect snap ring grooves for wear
- Replace leaking seals while the axle is out
