What does differential additive do?
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 fluid’s original frictional properties and eliminate chatter.
What is limited slip differential additive?
Kendall® Limited-Slip Axle Additive Concentrate is a special additive used to modify the frictional characteristics of axle lubricants for use in limited-slip differentials. It helps to eliminate chatter in limited-slip differentials when added to non-limited-slip API GL-5 gear lubricants.
What happens if your differential fluid is low?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
Does changing differential oil make a difference?
In most cases, you will need to change differential fluid every 30,000 to 50,000 miles. It’s important to stay on top of changing differential fluid because metal-on-metal contact creates heat from friction. It also weakens gears and wears down surfaces. That can lead to differential failure, which is a costly problem.
What happens if you dont use friction modifier?
The friction modifier increases the friction between the clutch plates. If you run a gear oil that has no friction modifier in it the diff will act more like an open differential. In short it will decrease the function of the lsd. It won’t cause any damage.
What lubricant does a differential use?
There are two types of differential fluid. One is mineral oil, which is a natural, crude oil-based fluid. The other is synthetic differential fluid, which is created in a lab. As with all synthetic oils, synthetic differential fluid oils can be fine-tuned for optimal performance.
Can you add too much limited slip additive?
If you add too much limited slip additive, you’ll notice your wheels will break loose super easy and you’ll get wheel-spin just making turns from a stop. If you make that mistake (like I did), just drain the oil and refill and you’ll be good.
How do you know if your rear differential needs fluid?
Here are the most common bad differential symptoms to look out for:
- Your vehicle is quickly going through oil.
- Difficulty steering.
- A loud front differential noise, such as the grinding of gears, clunking, or a “howling” sound.
- Rear differential noises.
- Extensive and inexplicable wear and tear on your tires.
How do you know if you need rear differential fluid?
What are the Symptoms of Bad Differential/Gear Oil?
- Burning Smell from the Differential. When you notice a bad smell coming from your gearbox, you should take it as a sign of bad differential oil which can be contaminated hence not operating as it should be.
- Weird Noises.
