Hello and good evening. Yes the differential must be removed, but you may be able to unbolt it and let it drop, without totally removing it. Try that first. Once you get that out of the way, the job will go as expected.
Your JA Expert,
No, it doesn't appear so. If you unbolt the axles at the differential, you will be able to completely remove it and get it out of your way completely. Once you unbolt the driveshaft, and disconnect the elect. connectors, removal of the mounting bolts will be all that is left and down it will come.
