What kind of bearings do you need on a Jeep Wrangler?
If you happen to break something on a YJ or TJ Dana 30 or Dana 44 (Rubicon TJ only) front axle, we strongly recommended carrying an extra stub shaft and axle nut at the very least to get your broken rig off the trail safely. Speaking of things to carry, you’ll need a 36mm for the ’87-’06 front axle nut, and a 35mm for the ’07-current JK model.
