# Service bulletin SIL 788

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

Altec has discovered that the cast aluminum bumper support brackets used by Freightliner on some affected units have cracked in the field. This can cause a lack of proper support for the front bumper and the cab guard on the vehicle. Altec requires the bumper support brackets on the chassis to be inspected no later than the next periodic maintenance interval or 30 days from the receipt of this SIL, whichever comes first. Affected units are certain LR7 aerial devices built on Freightliner M2\-106 chassis from April 2016 through November 2019.
