226 MAINTAINING YOUR VEHICLE Rear Axle Axle Lubricant Level Check Check the exterior of the axle for evidence of gear oil leakage every 12 months or 6,000 miles (10 000 km). This check should be made with the vehicle level and supported by the suspension, with the vehicle on the ground or raised on an axle and wheel type hoist. The axle lubricant level should be between the bottom of the filler plug and a point approximately 3/8 in (9.5 mm) below the filler plug. If adding axle lubricant, use only the manufacturer's recommended axle lubricant. Refer to the "Fluids, Lubricants, and Genuine Parts" in this section for the correct fluid type. NOTE: The Limited Slip Differential requires that a friction control additive be added when draining and refilling the axle lubricant. Change Axle Lubricant Drain and fill the axle at the intervals specified in "Maintenance Schedules" in Section 8 of this manual. Change the lubricant immediately if contaminated with water. See your authorized dealer for service. Appearance Care And Protection From Corrosion Protection of Body and Paint from Corrosion Vehicle body care requirements vary according to geographic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. The following maintenance recommendations will enable you to obtain maximum benefit from the corrosion resistance built into your vehicle.
