Volvo Repair: 1996 850 Volvo removing front Axle Nut, volvo 850 turbo wagon, electric impact wrench

Question
I have a 1996 Volvo 850 turbo wagon and the passenger wheel bearing is making a low hum sound between 30 and 60 km. I've tried removing the front 36mm axle nut with a small breaker bar unsuccessfully. Can you suggest how I can get this off and then how to back the splin out as I presume it will also be stuck.. For the nut would renting an electric impact wrench work. I've been putting liquid wrench on the nut hoping it would help. Also what is the torque setting when replacing the nut?
Thanks


Answer
Definitely not a small breaker bar, need long bar or impact wrench. I'm not sure an electric one will work, I usually use an 1/2 inch air impact which will need an air compressor.
If doing by hand, have someone sit inside and step on the brakes and using a long breaker bar, step on it to loosen nut. Good luck.
Also will need hub bearing kit, not just bearing
