摘要:
A telescoping steering column assembly includes upper and lower jackets having inner and outer surfaces and telescoping ends, respectively, and two sleeves disposed therebetween and having an annular cavity defined within each of the sleeves to hold bearings therewithin. One bearing is connected to the outer jacket and the other bearing is connected to the inner jacket. A method of making the assembly includes the steps of disposing the inner jacket within the outer jacket followed by disposing the sleeves therebetween and injecting a plastic material therethrough to form bearings. The plastic material is extracted from one of the apertures in each of the jackets to provide a sliding engagement between one of the bearing and the inner jacket and another bearing and the outer jacket.
