# Service bulletin SIL 780

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.

- Type: Service bulletin
- NHTSA id: 10187929
- Published by NHTSA: 2021\-03\-02

## NHTSA's summary

Altec has discovered that the EZ Trac hydraulic all\-wheel drive \(AWD\) system may have been improperly installed on some units. Incorrect steering adjustments can cause the front wheels to oversteer. This can damage the steering stop bolts, causing the tires to rub on chassis components. Incorrect hydraulic hose routing can subject the hoses to damage. This can cause fluid leakage, resulting in the loss of AWD assistance. Altec requires the following actions to be performed on the affected units no later than 30 days after receiving the SIL. \- Inspect the EZ Trac system using the Inspection Procedure provided in the notification. \- Have Altec make any required repairs.
