(Whose Fault Is It When Your Transfer Case Blows Up?)
A well-lubricated gear box means smooth driving for you and your vehicle! But if it goes out for lack of lubrication, or the wrong lubricant, it’s not the vehicles fault!
Gear lubricant is a special oil formulated for the extra lubrication needs of gear boxes such as the manual transmission, differentials, steering gear boxes and the transfer cases in four-wheel drive vehicles, especially those diesel pickups! These gears perform best when operating in a pool of oil … the right oil!
Normal use of your vehicle will subject these fluids to high temperatures which break down the fluid, causing it to become gummy. Once gummy, oil loses its ability to lubricate properly causing abnormal wear on gears and even leading to axle failure.
If gear box fluids get too low, bare metal contact and higher heat can occur causing premature wear on parts.
Differential fluid is one of the least checked fluids. Your vehicle differential is a gear box that allows your vehicle wheels to turn at different speeds. Properly lubricated differentials can help reduce tire wear, give you better road traction and steering stability.
Gear box lubricants should be serviced between 12 and 24 months or between 12,000 and 24,000 miles, depending on your vehicle and its individual driving conditions. Owners’ manuals give specific recommendations.
