A plug-in constant velocity joint has an outer race (12) and an inner race (14). The inner race has a plurality of splines and inner tracks. A cage (16) is located between the outer race and the inner race. A boot sleeve (20) is disposed against the inner race and has a first end portion, a middle portion, and a second end portion. The first end portion defines a race seat (58) and is in contact with an end of the inner race (14). The second end portion defines an inner ridge (66), an annular sleeve channel (68) and an outer ridge (70). A boot assembly (22) is coupled to the outer race (12) and comprises a boot retainer and a boot (76). The boot (76) comprises at least one inner axial groove ((96) and one outer axial groove (98). A plug-in stub shaft (24) is engaged with the boot sleeve (20) and both are drivingly engaged into the inner race (14). Air passes between the boot (76) and the boot sleeve (20) to equalize with the ambient environment by passing over the inner ridge (66), through the inner axial groove (96), the annular sleeve channel (68) and the outer axial groove (98) and over the outer ridge (70). |
