Yes, hopefully you can get the dust cover back on. The amount of pressure needed to pull that off is not much. Really next time you should get an axle puller that threads into the hub wheel stud holes and pushes the axle through the hub. Hammering it through is not the answer either because that can be hard on the bearing. A puller tool to pull the axle back through is nice to have as well.
