How do you unfreeze an axle?

To unfreeze an axle, start by lifting the vehicle and securely supporting it on jack stands. Inspect the axle for visible damage or rust and apply penetrating oil to the affected joints. Gently tap the axle with a hammer or use a pry bar to help break the bond, taking care not to damage any components. If necessary, heat the area with a heat gun to expand the metal slightly, which can aid in loosening the frozen parts.
