To be sure, consult a repair manual specific to your 1998 Oldsmobile Intrigue. These manuals will provide detailed instructions and diagrams showing exactly which socket sizes are needed for each step. A Haynes or Chilton manual are readily available.
Without that manual, I can only offer general possibilities, and using the wrong size could damage your vehicle. Expect to need sockets for things like:
* The axle nut: This is often a large size, possibly 30mm or 32mm (metric) but could be something else.
* Various bolts securing the CV joint to the transmission or wheel hub: These will likely be smaller than the axle nut, ranging from 10mm to 19mm (metric) but could be different again.
In short: Get a repair manual before attempting this repair. Trying to guess the socket sizes is risky and could lead to stripped bolts or other damage.
