its really a doable job. i did it with limited tools when i was young ... never having done it before while lying on the driveway covered with ice. i had a frozen bearing that would not turn and that was my daily driver. it wasn't really that hard ... i needed an air impact wrench to get the stub axle nut off - pounded the stub axle through and got everything else apart ... new sealed bearings put back in and everything was fine.
