How does a four wheel drive shaft attach to a transfer case?
Some drive shafts on four-wheel drive vehicles are made of two pieces with a front slip yoke and some are two pieces with a center slip yoke. The two-piece drive shaft with a center yoke attaches to a bolted on, built-in yoke sleeve into the transfer case. The yoke sleeve is put into the transfer case with a snap ring to hold it on.
Why is my transfer case output shaft leaking?
In many cases, these noises are caused by the reduction of lubricants inside the transfer case or metal-to-metal grinding. Step 1: Grab a flashlight and look under the four-wheel drive vehicle for any oil on the ground. Then shine the light onto the transfer case output shaft and look to see if the seal is leaking.
What causes the output shaft seal to bend?
This puts a lot of stress on the output shaft seal and makes the seal bend. When the seal is hard, bending the seal will allow fluid to escape the transfer case and allow dirt, debris, and water to enter into the transfer case. The most common sign of output shaft seal failure is the drip of gear oil leaking from the seal.
What is transfer case repair?
Transfer Case Repair. The transfer case is an essential part of your vehicle that is behind the transmission and directs power to the drivetrain. There are many variables that can cause a transfer case repair to be necessary from grinding sounds to low fluids, and our master mechanics will be able to make the diagnosis and repairs quickly for you.
What is a transmission case seal?
The seal that keeps fluid inside the transfer case and thus the transmission is vital for the smooth operation of the vehicle’s transmission. When fluid is leaking from a broken seal, it reduces the volume of fluid that is currently working inside the transmission.
What is a transfer case seal?
The purpose of the transfer case output seal is to prevent fluid from leaking out of transmission, where the transfer case is connected by way of the transmission’s input shaft. The seal also helps to keep fluid from leaking out of the front and rear output shaft to the differentials,…
What is the rear output shaft seal?
The rear output shaft is sealed to the driveshaft yoke by means of a rubber seal on the transmission. It is meant to contain the transmission fluid inside the transmission while the rotation of the driveshaft occurs.
