Getting them off the vehicle is easy, just pull them off. But you will destroy them in the process though. Getting them off a vehicle once installed without damaging them, even with a putty knife....dont really think its possible. Definately would take some patience! I would be impressed if you did!
Putting the new ones on you have to be careful and apply even pressure to avoid bending the pot metal under the rubber.
