Assemblies and Inspection of the Freightliner Spring Front and Rear Suspension Spring
Inspect the front and rear suspension spring assemblies for pitted, cracked, broken, or abnormally bent leaves, and extreme rust. If any of these conditions exist, replace the spring assembly. See of the Business Class® M2 Plus Workshop Manual for instructions.
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.
Important: On multi-leaf suspensions, closely inspect each component of the leaf spring assemblies, including the brackets, U-bolts, and related parts.
