Inspection of the Pivot Bushing Visual

To perform a visual inspection of the pivot bushing, it is not necessary to disassemble the pivot bushing connection. If the pivot bushing rubber flange(s) are intact and there are no signs of metal-to-metal contact, the bushing does not require replacement.

• The U-beam assembly is designed with the pivot bushings centered in each U-beam end hub. If the pivot bushing is not centered in each hub, it is an indication that the pivot bushing could be worn and a pivot bushing physical inspection is required.

• If the pivot bushing shows signs of torn, separated, or disconnected rubber, as shown in Fig., it could be the result of axle misalignment. If this condition is evident, a pivot bushing physical inspection is required.

• If the outer rubber flange(s) is missing, or there are shards of rubber visible, as shown in Fig., it could be the result of axle misalignment. If this condition is evident, the pivot bushing must be replaced.
