# Service bulletin 001\-26

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 TSB establishes the correct sequence for \(a\) setting and verifying the front axle knuckle stop screws to achieve the specified 45° wheel cut on the Hendrickson 10K front axle, and \(b\) setting the internal unloading \(poppet\) valves on the TRW THP60 steering gear so that hydraulic pressure is relieved just before axle stop contact in both directions.
