# Service bulletin SIL 819

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Certain 2017\-2020 Ford F350/F450/F550 chassis with Timbren springs installed near the chassis front coil springs can loosen over time and could eventually become disconnected. Altec requires the Timbren springs to be inspected no later than the next preventive maintenance interval or 90 days from the receipt of this SIL, whichever comes first. This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer’s warranty provider. Altec will perform the work for free at an Altec facility.
