I'd suggest getting the removal and installation tool. I did make my own tools for a single row bearing and they were barely adequate with the engine out of the car. I managed to damage the first replacement bearing shield installing it due to inadequate tooling and had to replace it. Not a big deal with the engine out, but if the engine was in the car it might have been a nightmare. The removal tool is the all thread / PVC / moulding blade combo (How's that for cheap!). The hook on the end is a threaded rod connector modified with an angle grinder and a torch to fit under the IMS nut.
This was barely adequate to pull a single row bearing, it is doubtful it would work for a double row bearing. The gray rings are what is left od a PVC fitting used for installation, and as stated earlier, I dinged the shield with it on the first bearing. Anybody guess what the bent screwdriver is for?
