Next I replaced my rear wheel seals. The rears are more difficult than the fronts since the rears have a retaining ring and the seals are much heavier than the front so they require different pulling tools the the fronts. The front seals come out and go in like any car seals.
The first step on the rears is to thoroughly wipe them clean so you can see the retainer and the notch:
Secondly use a heavy duty pick to pick out the leading edge. A thin pick will bend:
Here's the ring out:
This shows 2 types of pullers - the smaller one you'll recognize as a typical seal puller for a car wheel. This will work for the front seals since they are thin and easily removed with this tool. The rear seals are much heavier construction and will not pry and bend out. You will need to use a slide hammer with an L-lip attachment. This puller is a universal body shop puller with a 5lb slide hammer and a fixed heavy butt end and the other end is threaded to allow a dozen different kind of fittings:
First though you will have to pull the inside guts out of the seal so that the slide hammers L-tool can fit into the seal. You can use the standard car seal puller to pull the insides out. Here's a photo of the inside bits you'll be pulling out:
