The first bearing I did I used a friends press, for the second I got my self a 30 ton hydraulic ram with a hole down the center so it's kinda like the factory tool, still pricey but much less than $2500. If I remember correctly I used parts from the ATD 8625 kit and a big generic Chinese sleeve kit and a 3/4" grade 8 rod. I took the the knuckle off both times.
