4. Steer Axle Wheel End Cleaning Inspection Repair and Replacement As the wheel end is disassembled set all parts aside for thorough cleaning and inspection Careful inspection will help determine whether parts should be reused In many cases the causes of premature wear or failure will also be revealed Cleaning Assembles may be steam cleaned while mounted to the housing as long as all openings are tightly plugged Once removed do not steam clean any components Steam cleaning at this time could allow water to be trapped in passages leading to rust lubricant contamination and premature component wear The only proper way to clean the assembly is to disassemble it completely Other methods will not be effective except as preparatory steps in the process Wash steel parts with ground or polished surtaces in solvent There are many suitable commercial solvents available Kerosene and diesel fuel are acceptable WARNING GASOLINE IS NOT AN ACCEPTABLE A SOLVENT BECAUSE OF ITS EXTREME COMBUSTIBILITY IT IS UNSAFE IN THE WORK SHOP ENVIRONMENT Wash castings or other rough parts in solvent or clean in hot solution tanks using mild alkali solutions If a hot solution tank is used make sure parts are heated thoroughly before rinsing Rinse thoroughly to remove all traces of the cleaning solution Dry parts immediately with clean rags Lightly oil parts if they are to be reused immediately Otherwise coat with oil and wrap in corrosion res
