don't quote me on it, but i think it is the same as a front seal just pull the drive shaft and use a flathead screwdriver to pull the seal out, then push the new one back in place, u might want to feel for wear on your drive shaft before putting the new seal in, if there is wear on the area the seal goes, then u should either get an oversized seal, or a sleeve to put over the spline shaft to compensate for that wear and build it up to create a good seal...
