Drive Axle Repair Causes and Processes

Drive Axle Repair: Reasons for Need and What is it Comprised Of

Drive axles run from the differential into the wheels and are essential for any automobile to be able to move. Several other systems interface and interconnect with drive axles to power them and control their movement.

A Complex Piece Of Equipment

To many, drive axles seem like a simple, solid object. In actuality, it's a complex piece of equipment made up of two half axles connected to the differential and universal joints.

Drive axles have several important parts. Those parts include:

• Axle
• Constant Velocity (CV) Joints
• Drive Shaft
• Differential
• Universal Joint
• Axle Housing

What These Drive Axle Parts Do

1. Axle
The axle bears the weight of the vehicle, its cargo and its passengers. It has to withstand the strong forces generated by driving and braking. The axle also facilitates steering and absorbs some of the shock when driving on rough roads.

2. Constant Velocity (CV) Joints
The CV joints help keep a vehicle's body balanced and allow the wheels to move freely.

3. Drive Shaft
Drive shafts in automobiles allow torque and energy produced by the drivetrain to be transferred to the wheels and other parts of the automobile. In rear-wheel drive and four-wheel drive vehicles they enable the engine to power the rear axle.

4. Differential
The differential aims power coming from the engine at the wheels, slows the transmission's rotational speed before it's transferred to the wheels, and enables the wheels to rotate at different rates of speed.

5. Universal Joint
The universal joint helps the driveshaft transfer power flowing from the transmission and move it to the differential.

6. Axle Housing
The axle housing helps protect the axle and enables it to operate as efficiently as possible.

Drive Axle Problem

If the drive axle breaks or is not functioning properly, the vehicle can't move properly. Driving a vehicle that has drive axle problems is extremely dangerous.

If the drive axle breaks while someone is driving, it can cause serious injuries and major damage to the automobile that is difficult and expensive to repair.

Common Drive Axle Problems

Poor Lubrication
The axle joint in the CV axle assembly needs proper lubrication. Without it, friction and stress increase, raising the chances of breakage.

Worn Out Boots
CV joints have rubber boots to keep them lubricated and clean. These boots can split due to wear and need regular inspection and replacement.

Weight Overload
Most axles are designed for a specific load capacity. Exceeding the vehicle's weight rating can lead to axle breakage.

Symptoms Of Drive Axle Trouble

• Clicking Sounds
  Often heard when turning, indicating worn CV joints.
• Grease On The Tire
  Suggests damaged or leaking CV joint boots.
• Vibration While Driving
  Especially during acceleration, indicates joint failure or imbalance.

Consequences Of Driving With Drive Axle Problems

Accidents, Injuries, and Death
Driving with a known drive axle issue can result in serious consequences.

More Expensive Repairs
Delaying repairs increases cost. A $150 boot repair can turn into a $900+ axle replacement.

See An Auto Mechanic Immediately

If you realize your vehicle needs drive axle repair, immediately take it to an auto repair shop. Choose one that has a well-trained, licensed, experienced mechanic and the appropriate tools and equipment to do the job right.
