# Service bulletin SB32\-033

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

Freightliner Service Bulletin for Front Axle Spacer Replacement. This service bulletin replaces the version dated 05/01/2016. This bulletin is updated to include the parts list. Some vehicles may exhibit a lean \(right or left\) due to weight difference on the front suspension. While this does not affect the operation of the vehicle, it may be visually unpleasing to many customers. To correct this condition, replace the existing front axle spacer on the low side of the vehicle with a thicker one.
