Abstract
A telescoping joint assembly and a method for making a telescope joint assembly 10. The joint assembly 10 has a pair of members 12, 14 which are telescopically engaged. Assembly 10 further includes a resinous, plastic and/or polymer material 16 which shrinkably coats or lines the inner shaft 12 after the inner shaft 12 is heated and exposed to a substantially inert gas, thereby providing a relatively durable and substantially “low friction” bearing or surface 18 which is effective to promote and/or assist the telescopic sliding motion between the members 12, 14.
