Jeep WJ Dana 30 Re-Shaft

After busting the twigs inside the front axle of our 1999 Jeep Grand Cherokee, we decided to refit with some real lumber.

If you own a Jeep WJ Grand Cherokee with a Dana 30 up front and are running, or would eventually like to run, 33-inch or larger tires, you will definitely need to upgrade your factory axleshafts to accommodate the increased stress. On our ’99 WJ, we had been running 34-inch tires for a while and have already gone through two left side ’shafts. The left side seems to self-destruct more easily, primarily due to it’s shorter length (than the right side axleshaft), which means less flexibility.
