The invention provides a method that can be applied, for example, to seal a constant velocity joint. The invention includes a method comprising the steps of substantially sealing the constant velocity joint with the primary boot which includes first and second ends, fixedly associating the first end of the primary boot with the constant velocity joint, and slidably associating the second end of the primary boot with the shaft which extends from the constant velocity joint. In one aspect, the invention includes a primary boot having a body defining a substantially smooth interior surface and a secondary boot associated with the primary boot and spaced from the interior surface. In another aspect, the invention includes a constant velocity joint having an outer joint member, an inner joint member positioned in the outer joint member, a plurality of ball members positioned between said outer and inner joint members, and a shaft engaged with and extending from the inner joint member. The primary boot is fixedly associated with respect to the outer joint member and slidably associated with said shaft.
