Wheel bearing question. Rocky/Feroza/Sportrack/whatevver its called in your part of the world

Got a little play in the front hubs so Im trying to repack/inspect or replace the front wheel bearings. Not a problem for me, done plenty on different vehicles in the past. My problem is I don’t know what size the HUGE locknut is that holds them on. I have a wheel bearing socket set but it only goes up to 39mm or 1.5". That thing is huge! Service manual says use SST 1234567whatever. Tried to google it and got nothing. Sockets over 2" deep well get expensive so I wanted trusted info before I spend money on it. Any help is much appreciated!

I don’t no the size, but I would measure the Hexagon size and find the corresponding socket using that.
