2002 Ford Expedition Air Suspension Compressor Parts Q&A

• Q: How to Safely Service and Repair the Air Suspension Compressor on 2002 Ford Expedition?

  A: An essential requirement prior to executing compressor/pump maintenance involves verifying an absence of pressure within the air spring for protection against vehicle harm along with personal injury risks. High-pressure air discharge without control occurs when disconnecting air lines from an air compressor thus endangering personnel. The vehicle repair process requires the New Generation STAR (NGS) Tester to perform thorough venting of the compressor/drier assembly. The service begins with disconnecting the battery ground cable followed by windshield washer pump and reservoir separation and quick connect locking ring compression on the air compressor lines while the operator pulls back the air lines. Unplug the air compressor electricity and disconnect its bracket bolts before taking out the drier unit and compressor system assembly. Proper reinstallation of the air lines requires that you insert the white air line completely into its fitting. The adaptive strategy learning process of the vehicle requires a drive distance of at least 16 kilometers (10 miles) following the battery connection and disconnection unless the vehicle develops abnormal drive symptoms. Install the air compressor followed by inflating the air suspension system before renewing the removal procedure.
