# Service bulletin FDM\-TSIB\-020

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

This bulletin provides instruction for drilling a drain hole near the base of the left and right superstructure supports to allow any water that enters the support to drain. Trapped water in the superstructure support can freeze in cold weather causing the support to rupture at the base. Current production superstructure supports now have a drain hole.
