Not adding limited slip additive to your differential fluid can result in decreased performance and a shorter lifespan of the differential system. Proper maintenance and care of your vehicle is essential in ensuring its optimal performance and longevity.

One crucial aspect of maintenance is ensuring the differential system is functioning correctly. To achieve this, adding limited slip additive to the differential fluid is necessary. This additive improves the performance of the limited-slip differential by providing better grip and reducing wear on the components within the system.

If the limited slip additive is not added, the differential system may experience reduced performance and a shorter lifespan. Therefore, adding the correct amount of limited slip additive during differential fluid replacement is imperative for the differential system’s optimal performance and longevity.

Limited Slip Differential System Explained

Differential system plays a crucial role in the smooth functioning of your vehicle. The differential system’s primary function is to transfer power evenly between the wheels that are rotating at different rates. However, if your vehicle has a limited-slip differential, it means that the differential mechanism has been modified to provide better traction control, especially on wet and slippery roads.

Let us dive deeper into how limited-slip differential works.

Working Mechanism Of Differential

The differential system comprises several gears and bearings that work together to transfer power between the wheels. It does this by allowing the wheels to rotate at different speeds without interfering with each other. The differential system is located in the middle of your vehicle’s front and rear axle.

The Inclusion Of Clutch Packs

When you add a limited-slip differential to the differential system, it consists of extra features like the clutch packs. The clutch packs work alongside the gears and bearings by applying resistance to the gear mechanism. This means that the wheels that are rotating faster are slowed down, transferring power to the slower-moving wheels for better traction.

Here are some advantages of having clutch packs in the limited-slip differential system:

  • The clutch packs maintain an equal distribution of power between the wheels during normal driving conditions.
  • It works effectively on slippery roads to prevent wheel slippage.
  • Provides additional control when making turns.

Purpose Of Limited-Slip Differential

Having a limited-slip differential in your vehicle comes with certain benefits. Here are some reasons why you might want to consider getting one:

  • Improved traction: Limited-slip differentials provide better traction control, especially in wet and slippery conditions. This keeps your vehicle from slipping and sliding while on the road, avoiding potential accidents.
  • Better performance: Limited-slip differentials help to improve your vehicle’s overall performance by giving it better acceleration, especially when exiting corners or bends.
  • Reduced wear and tear: With a limited-slip differential, your vehicle’s wheels rotate with less force, reducing wear and tear on the tires, gears, and bearings.

Having a limited-slip differential in your vehicle is highly recommended, especially if you drive in wet and slippery road conditions. It enhances your traction control, improves your vehicle’s performance, and reduces wear and tear on various parts of your vehicle.

Investing in a limited-slip differential system is a wise choice.

What Happens If You Don’T Add Limited Slip Additive

If you’re a vehicle owner, you know how important it is to take care of your car. One of the most critical components of your automobile is the differential system, and failing to add a limited slip additive can have dire consequences.

Let’s dive into the details and understand the potential risks of not using this additive.

Consequences To Differential System

The differential system comprises various components, such as gears, bearings, and clutches. Adding a limited-slip additive protects these parts from wear and tear, extending their lifespan. However, not using the additive can lead to a host of problems, including:

  • Reduced traction: A limited-slip differential system prevents loss of traction, which helps you stay in control while driving. Without the additive, your vehicle will struggle to maintain traction, leading to tire slippage.
  • Overheating: Differential gears create friction when they come in contact with each other, producing heat. The limited slip additive helps reduce friction and minimize overheating, which can cause significant damage if ignored.
  • Premature wear and tear: Since gears, bearings, and other components in the differential system aren’t protected from wear and tear without the limited slip additive, they can break down prematurely, leading to costly repairs.

Noticeable Noise, Vibration, And Harshness (Nvh)

Without the right amount of limited-slip additive, your differential system may exhibit noticeable noise, vibration, and harshness (nvh). These symptoms are usually noticeable under various driving conditions, including when you’re accelerating around a corner or making a turn.

  • Noise: When the gears and other components in the differential system are not protected, they can produce an excessive amount of noise. This noise can be anything from a hissing sound to a knocking noise, making it uncomfortable to drive your car.
  • Vibration: Again, due to excessive wear and tear, the differential system may start to vibrate. This can cause a tingling sensation in the steering wheel and significantly impact the driving experience.
  • Harshness: Harshness relates to how your vehicle feels when driving, and without the right amount of limited-slip additive, the driving experience can become rough and uncomfortable.

Damage To Clutch Pack Or Other Components

Finally, failing to add a limited slip additive can cause damage to the clutch pack or other components in the differential system. Clutch packs are responsible for transferring power between the wheels of the vehicle, so any damage can impact the vehicle’s performance.

  • Clutch pack damage: If the clutch pack is damaged, your vehicle’s traction will be severely impacted. The wheels may stop working altogether or slip too much, making it virtually impossible to drive your car.
  • Other damage: Besides the clutch pack, other components in the differential system can also suffer significant damage without the protection of the limited slip additive. For example, bearings can break down, seals can start to leak, and gears may become damaged, leading to a complete system failure.

The limited-slip additive is an important component that protects your vehicle’s differential system. The risks associated with not adding the protective additive are severe, and we hope this blog post will help you understand the importance of keeping your differential system well-maintained.
