Addressing Problems with Limited-Slip Differentials

Addressing Problems with Limited-Slip Differentials

If the frictional properties aren't correct, abnormal clutch engagement and disengagement called chatter will occur.

Clutch-based limited-slip differentials are common on many automotive applications such as trucks and SUVs, but they present a unique problem.

These differentials often use different clutch configurations, either cone or flat type, made with various materials and frictional requirements. When both wheels have ample traction, the clutch plates bind together tightly, sending consistent power to each wheel. When one wheel slips, additional power is sent to the other wheel based on the frictional properties of the clutch packs. This is where the gear lubricant’s frictional properties play an important role in functionality and performance.

If the frictional properties aren’t correct, abnormal clutch engagement and disengagement (“chatter”) will occur. Chatter happens when turning a corner and the differential clutches are experiencing stick-slip instead of smoothly slipping. Not only does it cause annoying noise, popping, vibration and chatter, but it also causes premature wear and differential failure.

This is where an additive such as Lubegard Limited Slip Supplement can be used to modify the fluid’s frictional properties to correct the problem.

What Are Direct Ignition Coils?

The stick coil eliminates ignition wires and utilizes wasted space by fitting neatly into the spark plug bore.

Ignition coils transform battery voltage into the higher voltage needed to jump the spark plug gap and efficiently ignite the air-fuel mixture in an engine.

Direct ignition coils are by far the most common type of ignition coil found in modern direct ignition systems, and they’ve been adopted by most of the major automakers. In this design, the coil mounts directly on top of the spark plug, eliminating the need for an ignition wire.
