That's the tool you need but there is a difference between the ones that are made for the 8.5" axle bearings and the 8.6" axle bearing like you have. It will destroy the bearing but you're replacing them anyway. It takes a different tool to install the new ones. MAC, Matco, Snap-on, Cornwell should all have what you need but I would try to borrow 'cause they're not cheap.
