How to Repair a Driveline

An automobile driveline connects the engine to the axles, giving them the power to turn and move the vehicle. It connects the engine to these parts via a number of joints and clamps. When these parts are faulty, the car might shudder when you give it gas, or it might clunk loudly when the transmission is downshifted. The noise, as well as leakage at the joints, are signs that you need a repair. Most home mechanics can handle minor repairs, which involve replacing rubber boots and adding grease. But for major repairs, its best to take the vehicle to a licensed automotive mechanic. If you are doing the work yourself you will need access to a hydraulic car lift.

Instructions

1

Drive the car into a workspace with a hydraulic lift. Attach the lifts wheel or frame locks onto the car. Initiate the lift so that the car is suspended. Place the lift safety blocks into position to secure the lift arms in place. This will ensure the the car wont crush you if the hydraulic pressure begins to fail.

2

Locate the CV joint boots at the end of the driveline. Examine them for tears or leakage of grease and oil. If you find tears or leaks, pull the old rubber boot off the linkage because it needs to be replaced. Examine the CV link of the driveline to the axle and the opposite end at the transmission. Use a flashlight if visibility is poor. Look for corrosion or rust if the CV boot was torn, opened or exposed.

3

Regrease the CV joint and insert a new CV boot onto the driveline axle and transmission connections if the joints are in good working condition and the rubber boot was bad. If the boot is still good and shows no signs of tears or leaks, slip it back onto the joint.

4

Lower the car and bring it to a licensed mechanic if you can see clear signs of corrosion to the CV and transmission joints of the driveline. Have the mechanic lift the car with his equipment. Show him what youve observed and where the corrosion is. Have the mechanic replace the driveline and joint couplings as necessary.
