How does a Chevrolet limited slip differential work?

How does a Chevrolet limited slip differential work?

The clutch packs on both sides are the limited slip side of the differential. As the drive shaft turns the pinion, it meshes with the ring gear and turns the entire differential. As the differential turns and the vehicle moves straight ahead, the spider gears do not turn or move from position. The gears just turn in an elliptical pattern.

Where are the spider gears on a limited slip differential?

Observe the spider gears in the upper and lower hemisphere of the center of the differential. The side gears on either side are meshed with the spider gears. The side gears have splines in the center where the axles slide into them, and are held in place by their splines. The clutch packs on both sides are the limited slip side of the differential.

How big is the center pin on a limited slip differential?

The pin is approximately ¾ of an inch in diameter and the same length of the differential case. Its purpose is to support the spider gears to give them a pivotal point and keep them at a 180-degree separation. It also keeps them in constant contact with the side gears. The center pin prevents the axles from moving inward.

What’s the first step in disassembling a Chevy?

The first step is to suspend the chassis and let the rear extend freely under the car. Use the properly rated floor jack to jack up the car and place the correct jackstands under the frame rails. Remove the lug nuts and take off the rear wheels. The shocks are fully extended and can be unbolted.

What’s the best way to disassemble a Chevy differential?

It depends on your preference and tools available. The first step is to use a socket and ratchet or a wrench to remove the cover bolts. Use a soft mallet to break the seal or use a pry bar, but be careful not to damage the mounting surface of the center section.
