WAKEFIELDS GEAR EASE NO.1 OIL FOR HYPOID GEAR REAR AXLES. Origin. An alternative lubricant (for hypoid gear rear axles) to Whitmores No.O Compound, cheaper and more easily obtainable. Experimental Test Report. 34 production axles have been passed through the standard dynamometer test using this lubricant. There have been no failures. This oil does not settle out so much as Whitmores and does not cling to the axle casing to such an extent. Road Test Report. The following mileage has been completed successfully on the road: 25-EX (in France) 17,000 19-EX - 7,600 20-EX - 9,200 22-EX - 7,200 27-EX - 1,500 Total - 42,500 Weight of Old Part.
