To replace the hub on this vehicle many special tools are needed. Also at the same time the wheel bearing has to be replaced due to the hub cannot be removed without damage to the wheel bearing. The wheel bearing is then installed and then the hub is drawn into the wheel bearing.
The brakes and brake shoes need to be removed first.
Then you can remove the hub and wheel bearing.
One trick that you might be able to do is to have someone hold pressure on the axle and carefully tap the hub into place. Once in fare enough the hub bolt can be used to draw it in the rest of the way. The only bad thing is you risk damage to the wheel bearing if the inner race walks out by not using the special tools. It can be done but sometimes the race will walk out.
I hope this is helpful. Please accept this answer and Thank you.
