How does a limited slip differential LSD work?

Model: (Various brands) Various
Part: Differential

Video tutorial

In this video we see how a limited slip differential LSD works and why it would be important to have it installed on our car: in a standard differential, the driving torque is distributed equally to the two wheels of an axle. This means that if one wheel encounters a low traction surface and starts to slip, the other wheel, even if it has traction, will receive little or no torque, compromising traction.

The LSD (limited slip differential) is designed to limit this problem. When one wheel starts to rotate faster than the other due to a loss of traction, the LSD intervenes, transferring some of the torque to the wheel with greater traction.

This improves traction and vehicle stability. There are various types of this mechanism, each with its own operation: friction, bevel gear and Torsen where a system of planetary gears is used to distribute torque more precisely and continuously.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
