Insanely tight rear hub nut.. HELP! Options

[mrdezyne]

Trying to tear down my rear brakes and suspension to start a rebuild but I have hit a stone wall with the hub nuts on both sides. Are these things torqued with a 3ft cheater bar or something? I have already tried penetrating oil and heat cycles. The threads are not rusty nor are the nuts. Nothing is rounded off..... yet. Is there a secret here or what?

You can "drop the suspension" w/o undoing that nut, just unbolt the CV from the hub. You only need to remove that nut if you plan to remove the hubs, and you only need to do that if you plan to replace the rear wheel bearings.

If you ARE planning on replacing the rear wheel bearings, then you really MUST remove those nuts before you disassemble anything else, or you'll never get them loose.

If by rebuilding the rear suspension, however, you only intend to replace bushings and shocks/springs, then you can leave the hubs in the trailing arms. Note that removing the hubs often destroys the rear bearings, so if those bearings are in good shape, don't remove the hubs.
