Overview
The G2 Dana 44 YJ/XJ/TJ 30 Spline Rear Chromoly Axle Kit Disc, part 96-2045-1-30, is a rear axle kit for the Dana 44 rear with disc brakes. The title and short text tie it to Jeep YJ, XJ and TJ Rubicon applications.
G2 says its rear axle kits are made from high tensile alloy steels and are forged and heat-treated for strength. The kit is meant so that the axle shafts are not the weak point of the driveline.
Key features
- Dana 44 Rubicon disc brake layout
- 30 spline
- 5-lug, dual drilled 5×4.5/5.5
- Forged and heat-treated high tensile alloy steel
- Includes wheel bearings, seals and screw-in wheel studs
Driveline and Rubicon fit
A Dana 44 rear is a heavy axle, and the Rubicon disc setup puts the axle shafts and hubs under higher loads when the vehicle crawls over rock or carries gear. Keeping the carrier, shafts and bearings matched helps the whole driveline work as one system, so inspect the pinion seal and carrier bearings whenever the axle is opened.
When choosing parts, match the spline count, flange pattern and carrier type before buying. Upgrades like a locker or larger gears are often installed at the same time as new shafts, and the new parts should suit the same spline end. Regular fluid changes help protect the gears and bearings. Check fluid levels after the first few runs, and look for leaks around the axle seals and cover gasket.
