Check The Front Suspension

Inspect the front spring assemblies for cracked, broken, or abnormally bent leaves. If any of these conditions exist, replace the spring assembly; for instructions on this and all following replacements see  of the Western Star 47X and 49X Workshop Manual.

Inspect the spring pin bushings. If there is any indication of the outer bushing casing moving within the spring eye, the complete spring assembly must be replaced.

For threaded and bronze bushings, ensure the center pin is free to rotate within the outer bushing. If the pin is seized, replace the complete spring assembly.

For maintenance free rubber bushings, inspect the bushings at the forward spring eye and shackle. If there is any indication of the rubber bushing being cracked or damaged, replace the bushing.
