A bushing is suspended by a pair of wavy washers so that binding between the bushing and a shaft mounted within the bushing is avoided when the axis of the shaft is not exactly perpendicular to its mounting bracket having a hole within which the bushing is disposed. The wavy washers also are preloaded against each other during assembly to produce the necessary drag for proper operation. A shaft 1 (Fig. 2) is inserted into a bushing 2 until a shoulder 3 on the shaft 1 engages an end face 4 of the bushing 2. After a first wavy washer 5 is installed over the bushing 2, the shaft 1 and the bushing 2 are inserted through a hole 6 in a mounting bracket 7. Then, a second wavy washer 8 and a thrust washer 9 are installed over the portion of the bushing 2 protruding beyond the mounting bracket 7.
