How Does a Driveshaft Work?
One of the simplest and most important parts of a vehicle is the driveshaft. Responsible for transferring the output of the transmission to the axles, it is essentially a shaft that drives the vehicle. Though it has a basic function, it plays an incredibly crucial role in vehicle operation and is the link between a revving engine and a moving car.
First, it’s important to know that front-wheel drive vehicles do not use driveshafts. Instead, the transmission and axle are combined into one unit called a transaxle. However, on rear-wheel and four-wheel drive vehicles, the transmission and axle are separate. This means that the turning motion of the transmission needs to be transferred to the axle in some form.
Symptoms of Driveshaft Problems
Vibrations/Shuddering
Vibrations from the driveline are a good sign that the driveshaft is failing. This is usually caused by the driveshaft not being bolted down well or the unit being out of balance. Of course, if it has been smacked by a rock while wheeling or is rusted and rotted, issues will be evident. But in all reality, the likelihood of this being a cause for failure in a daily driver is very far off.
Loud Noises
U-joints allow a drive shaft to pivot. They can also be a common culprit of drive shaft problems.The most common point of failure with a driveshaft assembly is the U-joints. The U-joints use bearings inside to keep the joint moving freely. Over time, these bearings will wear out and the u-joints will need to be replaced.
Difficulty Turning
Driveshaft problems can make it difficult to control the vehicle’s ability to turn. If you feel hesitation or resistance when turning, or difficulty maneuvering in and out of parking spaces, it could be a sign that your driveshaft is on its way out.
How to Remove a Drive Shaft?
Something you should know that may not be thought of is when a driveshaft is removed the car will no longer be in park. The car will roll because the link between the drive wheels and transmission is removed. You will need to raise the car or truck up using a floor jack and jackstays. Wear protective eyewear and gloves before you begin.
1. Mark the Driveshaft
Mark the driveshaft orientation before beginning. This will help return the driveshaft to its original position on the differential which can help avoid driveline vibrations once the driveshaft is reinstalled.
2. Remove Driveshaft Bolts
Remove the shaft differential flange mounting bolts. These bolts will be very tight so use good quality tools to avoid stripping. Some bolts can head 12 point heads as in this example which used a 13mm 12 point socket to remove. These bolts also use lock tight to avoid coming loose while in operation and can be reapplied when reinstalling.
3. Remove Driveshaft Flange
Using a plastic hammer gently shock the driveshaft loose from the differential flange by striking the rear yoke (U joint mount). At this point the back half of the shaft will be free so hang onto it. On some cars there will be a center support which must be undone by removing the two center support mounting bolts. When removing an older vehicle drive shaft use electrical tape to wrap around the u joint cups so they don't fall off and release the cup needle bearings.
4. Remove Driveshaft
Using both hands gently slide the driveshaft from the transmission or transfer case. A small amount of fluid might leak out so have a fluid catch basin ready. This would be a good time to replace leaking transmission tail housing seal, universal joints or if removing the transmission or differential repairs are needed.
5. Check U joints
At this point the U joint at either end of the shaft should be checked. Grasp the yoke and move it in all directions. It should be a smooth motion with no rough spots or play in any direction. If play or rough spots occur then the U joint needs to be replaced.
6. Reinstall Driveshaft
Before re-installing the driveshaft apply a small amount of grease to the yoke. This will help lubricate the output shaft seal in the transmission or transfer case.
There is a dust boot along with the rear seal which is incorporated within the transmission or transfer case tail housing seal. This transmission or transfer case output shaft is where the driveshaft connects.
Care must be taken when reinserting the driveshaft yoke as not to damage the seal. Gently guide the yoke into place over and onto the output shaft.
7. Reinstall Flange Bolts
Once the front yoke is installed pull the driveshaft back into place while inserting a mounting bolts by hand to avoid cross threading.Finish installing the mounting bolts while making sure the alignment marks are together.Tighten the bolts evenly and in a cross pattern to factory specs which is usually 55-65 foot pounds of torque. If any fluid was lost during the job check and refill the transmission or transfer case after the shaft has been reinstalled and you are all set.
