How does Chevy locking differential work?

Understanding Chevy Locking Differential
A locking differential, specifically the Eaton G80 automatic locking differential, is a seamless function that automatically locks the rear axle if one wheel starts to slip, enabling both rear tires to find purchase. This system enhances the capability of Chevrolet trucks equipped with 2WD and 4WD, allowing them to navigate through challenging terrains such as snow, ice, mud, and slush. The G80 locking rear differential has been a staple in Chevrolet trucks for over 40 years, providing enhanced traction and control in various driving conditions.
The locking differential consists of numerous gears, clutches, and often pneumatic and electronic assistance to engage and disengage the differential. When engaged, it ties both axle shafts of a single axle together, applying even power to both wheels to maintain traction. This feature is particularly useful during off-road driving, as it helps maintain traction during times of limited traction, extreme articulation, or uneven traction, allowing the vehicle to climb over tricky obstacles.
The Eaton G80 automatic locking differential allows rear-wheel-drive trucks to go places traditionally reserved for pickups that benefit from four-wheel drive. When one of the rear wheels starts to spin looking for traction, the rear axle locks automatically, enabling both rear wheels to propel the truck out of challenging situations.
In 2015, the G80 locking differential system became standard for all Chevrolet trucks, including those labeled as Z71s. Before 2015, the system was only used in custom vehicles. The Z71 off-road package, available for Chevrolet Trucks, includes the rear differential locking system, with the standard model being the G80 system made by Eaton.
The lockup and disengagement processes of the G80 locking differential happen instantly and are practically imperceptible to the driver. The ride is smoother because the G80 operates mostly as an open-type differential in normal driving conditions. There are no buttons to push or electronic settings to engage, as the G80 does its job instantly and quietly, allowing drivers to go about their job with confidence.
Overall, the Chevy locking differential, particularly the Eaton G80 automatic locking differential, plays a crucial role in enhancing the traction and control of Chevrolet trucks, enabling them to navigate through various challenging terrains and driving conditions with confidence and ease.

What are the disadvantages of diff lock?

Disadvantages. Because they do not operate as smoothly as standard differentials, automatic locking differentials are often responsible for increased tire wear. Some older automatic locking differentials are known for making a clicking or banging noise when locking and unlocking as the vehicle negotiates turns.

What happens when you drive with differential lock?

By engaging the diff-lock, whether it be factory standard or fitted after-market, the diff is “locked” and begins to drive both wheels evenly. This allows not only the wheel without traction to continue to spin in the hope of gaining traction, but more importantly, begins to drive the well-grounded wheel.

Is it better to lock the front or rear differential?

If you can only choose one locker for your 4WD, you should put it in the rear because when climbing hills, it will transfer more weight, traction and drive to the rear, and the rear diff lock will push you up where you want to go.

Can you turn on diff lock while moving?

To Engage (Lock)
Some vehicle manufacturers will allow the differential locks to be engaged while moving but only if the vehicle does not exceed 40kph and there is no wheel spin. Let up momentarily on the accelerator pedal to relieve torque on the gearing and allow the sliding clutch to fully engage.

Which is better limited slip or locking differential?

Lockers are tougher. Limited slips direct torque to both tires and when slippage occurs the unit directs torque to the tire with the best traction. LSDs do not generate 100% lock-up.

How do I know if my diff lock is working?

Forward. So I’m going to turn it in the opposite. Direction that. My other person is holding the tire on the other side. When. I turn it forward the tire should unlock the rear end should unlock.

Is locking differential worth it?

For the avid offroader, locking differentials are essential. No matter how extensive your ride’s modification sheet is, you can’t conquer obstacles without putting adequate traction to the ground. A factory limited-slip differential will likely be sufficient for the daily driver that performs occasional mild wheeling.

Why would you want to lock the rear differential?

A locking rear differential, once engaged, does not allow both wheels to spin freely. By ensuring that both wheels spin at the same rate, and applying unequal torque to each tire on the axle, the risk of losing traction or spinning out decreases dramatically.

How do you engage rear locking differential?

Control do not work when diff lock is activated. The rear differential lock automatically disengages when speed reaches 19 miles.

How fast can you drive with locking differential?

25 mph
This is a function that many adventurers consider necessary to equip a vehicle. How fast can you drive when the differential lock is engaged on the vehicle? When using the differential lock, your speed should not exceed 25 mph.
