This is the tool I use remove and install rear wheel bearings:

it's a coil spring compressor available from Amazon for 25 to 40 bucks, and possibly rentable from some autoparts stores like Autozone and Checker.
I use it with a circular piece of scrap steel cut into a big steel washer, a 30 mm Harbor Freight impact socket, an extra bearing (used is ok), and a couple of other impact sockets of no particular size that are used lengthwise to space the tool from the trailing arm housing:

for removing, the beveled edge of spring compressor fits nicely against the bearing on the backside as the bolt is routed through the bearing. On the front side, the steel washer installed on the bolt pushes against the smaller impact sockets which rest against the trailing arm bearing housing. It's a little tricky to setup the impact sockets so that the bearing doesn't hit against them as it comes out, but with three hands it's easily done.
For installation, the 30 mm socket is just the right size to be a guide so that the used bearing is perfectly aligned to push on the new bearing. On the back side, the washer lines up against the back of the trailing arm housing, and the power of the bolt easily pushes the bearing uniformly into the trailing arm housing.
