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.

What is claimed is: 1. A telescoping steering column assembly comprising: an outer jacket having inner and outer surfaces and a first aperture extending between said surfaces; an inner jacket having inner and outer surfaces and a second aperture extending between said surfaces and engaging in telescoping relationship with said outer jacket; and a bearing disposed annularly about said outer surface of said inner jacket and slidably engaging said inner surface of said outer jacket and having a third aperture wherein said first and second and third apertures are operable to be aligned for receiving liquid plastic with said bearing abutting an end of said inner jacket. 2. The telescoping steering column assembly of claim 1 further comprising: a second bearing disposed annularly about said inner surface of said outer jacket and slidably engaging said outer surface of said inner jacket and having a fourth aperture wherein said outer jacket includes a fifth aperture and wherein said fourth and fifth apertures are operable to be aligned for receiving liquid plastic. 3. The telescoping steering column assembly of claim 2 wherein said first and second and third apertures are aligned when said fourth and fifth apertures are aligned. 4. The telescoping steering column assembly of claim 3 wherein said bearing and said second bearing radially overlap one another. 5. The telescoping steering column assembly of claim 4 wherein said third aperture is larger than said first aperture. 6. The telescoping steering column assembly of claim 4 wherein said fourth aperture is larger than said fifth aperture. 7. The telescoping steering column assembly of claim 4 wherein said bearing includes a lip extending radially inwardly past said outer surface of said inner jacket. 8. The telescoping steering column assembly of claim 2 wherein said second bearing abuts an end of said outer jacket. 9. The telescoping steering column assembly of claim 8 wherein said end of said inner jacket is received in said end of said outer jacket. 10. The telescoping steering column assembly of claim 2 wherein said second bearing includes a lip extending radially outwardly past said inner surface of said outer jacket. 11. A telescoping steering column assembly comprising: an outer jacket having inner and outer surfaces and a first aperture extending between said surfaces; an inner jacket having inner and outer surfaces and a second aperture extending between said surfaces and engaging in telescoping relationship with said outer jacket; a bearing disposed annularly about said outer surface of said inner jacket and slidably engaging said inner surface of said outer jacket and having a third aperture wherein said first and second and third apertures are operable to be aligned for receiving liquid plastic; and a plastic projection extending in the second aperture and in the third aperture to fixedly engage the bearing and the inner jacket together, wherein said plastic projection is formed in situ with respect to the second aperture and the third aperture. 12. An assembly as set forth in claim 11 further including a second bearing disposed annularly about said inner surface of said outer jacket and slidably engaging said outer surface of said inner jacket. 13. An assembly as set forth in claim 12 wherein said second bearing defines a fourth aperture and wherein said outer jacket defines a fifth aperture with said fourth and fifth apertures operable to be aligned for receiving liquid plastic. 14. An assembly as set forth in claim 13 further including a plastic projection extending in said fourth and fifth apertures to fixedly engage said second bearing and said outer jacket together. 15. An assembly as set forth in claim 13 wherein said first and second and third apertures are aligned when said fourth and fifth apertures are aligned. 16. An assembly as set forth in claim 13 wherein said second bearing abuts an end of said outer jacket. 17. An assembly as set forth in claim 13 wherein said second bearing includes a lip extending radially outwardly past said inner surface of said outer jacket. 18. An assembly as set forth in claim 11 wherein said bearing abuts an end of said inner jacket. 19. An assembly as set forth in claim 11 wherein said bearing includes a lip extending radially inwardly past said outer surface of said inner jacket. 20. A telescoping steering column assembly comprising: an outer jacket having inner and outer surfaces and a first aperture extending between said surfaces; an inner jacket having inner and outer surfaces and a second aperture extending between said surfaces and engaging in telescoping relationship with said outer jacket; a bearing disposed annularly about said outer surface of said inner jacket and slidably engaging said inner surface of said outer jacket and having a third aperture wherein said first and second and third apertures are operable to be aligned for receiving liquid plastic; and a second bearing disposed annularly about said inner surface of said outer jacket and slidably engaging said outer surface of said inner jacket and having a fourth aperture wherein said outer jacket includes a fifth aperture and wherein said fourth and fifth apertures are operable to be aligned for receiving liquid plastic.
