Wherefore, you must use additives or modified fluid to take care of those problems related to gears. If it spins in the same direction, you have a limited slip differential, or LSD. Instead of formulating multiple gear lubes of the same viscosity, but different frictional properties, to address occasional chatter in limited-slip differentials, gear-lube friction-modifier additives can be used to alter the fluids original frictional properties and eliminate chatter. How do I reset my garage code without the code? Its convenient squeeze-tube packaging provides quick and easy application to the gear housing. Is electronic limited slip differential worth it? Too little additive and it will lock up too hard and wear out too fast. Terms of Service - The MOPAR Limited Slip Additive should be added to the gear lubricant whenever a fluid change is made to an axle equipped with a Limited Slip Differential. Gear oil keeps components such as the ring and pinion gear set, spider and side gears, limited slip differentials, axles, bearings, and the like lubricated and running smooth. If both tires go forward when you turn one it's working or would at least appear to be with no load. No matter how much we praise Valvoline SynPower, it would be less. 3 Is posi traction the same as limited slip? If the other wheel spins in the opposite direction, you have an open differential. By design, it resists breakdown from high heat, preventing acid-caused viscosity changes and loss of gear protection. Since there is nothing in any differential that is not in a limited-slip differential, there should be no harm in using a friction modifier in a non-limited-slip differential, although there is no need for it. 5.Ok NOT to run friction modifier in limited slip? Highly effective for daily driving and works well in rain, mud, and snow. All differentials use gears, bearings and shims. Eventually it will destroy the clutches and render the limited slip useless.
