What size is the axel shaft nut on a Pontiac Montana van?

There's no single answer to the size of the axle shaft nut on a Pontiac Montana van. The size varies depending on the year and model of the van (different axle configurations were used over the years).

To find the correct size, you must consult your vehicle's repair manual or a reliable online parts database (like AutoZone, Advance Auto Parts, or RockAuto) using your van's Year, Make, Model, and Engine. These resources will provide the precise specifications for your specific vehicle.

Attempting to guess the size could lead to using the wrong tool, causing damage to the nut or axle.
