-
- Inspect the load cushions for cuts and swelling. Cushions cut by the retaining lips of the saddles or frame hangers indicate the cushions may not be the correct hardness or configuration for the vehicle operation.
- Inspect the lower side of the vertical drive bushings for evidence of torn or shredded rubber. Check that the concave washers are installed with the lips pointing downward.
- Inspect the saddles and saddle cap fasteners for wear. The allowable thrust washer wear in aluminum saddles is up to 3/16 inch (4.8 mm) into the saddles as measured at the top of the thrust washer diameter. Check that the locknuts are torqued to specification to prevent wear of the beam center bushings into the legs of the saddles. See of this manual for torque specifications.
Warning: Be sure that fasteners are torqued correctly. Fasteners that do not provide a tightly clamped joint between the frame and the hanger can cause premature fracture of the frame hanger, separation of components, loss of vehicle control, and possible personal injury or property damage.
