Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
If you want to risk damage to tailshaft, damage to diff mount rubber,damage to overextended axle half shafts & universals, damage to diff casing, damage to diff rear cover & oil seal causing diff oil leaks, damage to pinion front oil seal; sure go ahead!!!! My advice is NEVER jack an IRS vehicle by the diff.
