What is the carrier on a rear differential?
Carrier – Sometimes referred to as a Differential Case or Ring Gear Carrier. This unit transfers the motion from the ring gear to the axle shafts. Carrier Bearing – These are the bearings that ring gear carriers ride on. May also refer to the driveshaft support bearing used in multiple-piece driveshafts.
Does the rear differential affect the transmission?
The differential has one primary function: to provide the right amount of power to your tires so your vehicle can move at varying speeds. The differential ensures the right amount of speed is transmitted to your tires via the engine and transmission and allows your wheels to rotate as acceleration and power changes.
How much does rear differential service cost?
Combined with the few hours of labor required for their replacement, the typical rear differential cost of repair is between $200 and $400. If gears are required, that number jumps a bunch. Rear differential repairs that include a new gear set may be $1,500 or even higher between parts and the labor to replace them.
Are front and rear ring and pinion the same?
These sets are exactly the same. But when the rig is driven forward the pinion is putting pressure on the drive side of the ring gear in the rear and on the coast side of the ring gear in front.
Are all Dana 60 carriers the same?
All Dana 60 housings use the exact same carriers whether high pinion or low pinion. The high pinions have the same gear break as low pinions. The thick gears are available so that you do not have to change carriers.
Can you drive with a bad rear diff?
Technically, you can drive with a bad differential, but it is not wise. The problem may get worse, to the point where it leaves you stranded somewhere. It can also cause damage to other surrounding components. It is smartest and safest not to drive with a bad differential.
What does a bad rear end sound like?
In the case of a rear end, the noise can be a humming sound, a growl, or even a knock. Although any noise is bad, the noise does help in diagnosis. Ring and pinion gear-noise changes with vehicle speed and is usually unaffected by loads and turns.
When do you need a different carrier for a differential?
The point at which a different carrier is needed is referred to as a “Carrier Break”. The Gear Ratio at which Carrier Breaks occur varies, depending on the type of differential. For example, if you have a Dana 44 axle with a gear ratio of 3.73 and want to install a 3.92 or numerically higher gear set, you will need a different carrier.
How is power transmitted from the rear differential?
The power is transmitted from the rear differential along axle shafts that connect to the wheels and rotate to propel the vehicle forward. The gears inside the rear differential are bathed in gear oil, which lubricates the gears and bearings and cools them to prevent overheating.
Why do rear differentials need to be serviced?
One important aspect of servicing rear differentials is their lubrication. The gears within the differential need to be covered in gear oil, a substance that lubricates not only the gears but also the bearings. The oil also helps keep the components cool, so they do not overheat.
How big is the rear differential on a Chevy?
However, the 8.5- and 8.6-inch 10-bolts are extremely stout and effective rear differentials that can transmit up to 1,000 hp to the rear wheels. This Tech Tip is From the Full Book, CHEVY DIFFERENTIALS: HOW TO REBUILD THE 10- AND 12-BOLT. For a comprehensive guide on this entire subject you can visit this link:
