Front Suspension Check
Warning: Do not replace individual leaves of a damaged leaf spring assembly; replace the complete spring assembly. Visible damage (cracks or breaks) to one leaf causes hidden damage to other leaves. Replacement of only the visibly damaged part(s) is no assurance that the spring is safe. On front spring assemblies, if cracks or breaks exist in the two top leaves, a loss of vehicle control could occur. Failure to replace a damaged spring assembly could cause an accident resulting in property damage, serious personal injury, or death.
Inspect the front spring assemblies for cracked, broken, or abnormally bent leaves. If any of these conditions exist, replace the spring assembly. See your Western Star dealer for replacement.
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. Refer to of the Western Star Workshop Manual for instructions.
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. Refer to of the Western Star Workshop Manual for instructions.
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. Refer to of the Western Star Workshop Manual for instructions.
