Claim:
A method of installing a split boot at a device to-be-protected on axle, comprising the steps of: (a) enclosing the device to-be-protected on axle by a first boot layer, wherein said first boot layer has a longitudinal slit and defines an opening to receive said device-to-be protected on axle within said first boot layer; (b) wrapping a second boot layer around said first boot layer after the device to-be-protected on axle is enclosed within said first boot layer, wherein said second boot layer has a longitudinal slit and defines an opening to receive said first boot layer within said second boot layer; (c) sealing said opening of said first boot layer by said second boot layer, wherein said second boot layer wraps around and seals with said first boot layer at a position that said longitudinal slit of said first boot layer is off-set from said longitudinal slit of said second boot layer such that an outside surface area of said first boot layer is sealed with an inside surface area of said second boot layer to seal said opening of said first boot layer by said second boot layer for enclosing said device to-be-protected on axle within said first and second boot layers; and (d) when said second boot layer is worn, wrapping a third boot layer, having a longitudinal slit, to seal and enclose said first boot layer while said first boot layer is remained wrapping around the device to-be-protected on axle, wherein said first boot layer is wrapped by said third boot layer that said second boot layer is directly enclosed and sealed by said third boot layer at a position that said longitudinal slit of said second boot layer is off-set from said longitudinal slit of said third boot layer.
