Re: Changing front axle
Is there a difference between the 4.0 and 4.7 front end? Are they both D30s?
If I've changed axles on WJ's with 4.0 and it's easy. You remove the center axle nut, brakes, and rotors. Then remove the 3 bolts holding the wheel bearing assembly and gently remove the wheel bearing if you're reusing it. Once that's out the whole axle slides out. There might be something else minor, but that's basically it.
If you want to change out the whole front end (axle tube and all) that's a bit more involved and I haven't done that.
