Universal Joints and Driveshaft’s for Mazda Miata

The universal joints and driveshaft’s for Mazda Miata are part of the drivetrain system designed to maximize the touring capacity of the Mazda convertible. This is part of the overall powertrain that takes energy produced in the engine to the actual turning of the wheels on the road. Universal joints are functional for a number of years on the Miata, but regular service is required to keep them in good condition.

There are multiple components to the drivetrain system of a Mazda Miata and they are as follows.

• Driveshaft: Steel tube under the vehicle that connects the Miata engine to the wheels. The purpose of this component is to transfer the energy from the engine to move the wheels.
• Universal joint: Serves as a pivot point for the Mazda velocity being transmitted to the wheels at different angles and heights.
• Constant velocity joints (CV Joints): Joints that bend in all directions while turning the Miata wheels at a constant velocity.
• Differentials: Utilizing the converted power from the Miata engine, the differentials keep the wheels turning, but allow them to turn at different speeds.
• Axles shafts: Final stop for the energy coming from the transmission to the wheels.

The purpose of the universal joint is to connect rods that are fixed at different angles. There are three applications for a universal joint in the car:

• Connects the Miatas gearbox with the rear drive axle
• Connects the rear axle drive shaft with the rear wheel stub axle
• Connects the front axle drive shaft with the front wheel stub axle

As with all parts of the Miata, service according to the Mazda manufacturers schedule is an important part of the car ownership and upkeep. Following this schedule, the universal joints should be regularly lubricated to improve the life of these parts. If any of the following symptoms occur, there may be a problem with the joint.

• Vibrations can be felt throughout the car or it may feel like it is coming from under the roadsters seat.
• Strange noises are heard coming from under the Miata convertible.
• Red or pink transmission fluid is leaking.

Universal joints are part of the Mazda Miatas drive train system. When replacing a joint on the Mazda, it is recommended to replace them all. The following steps are needed to replace the Mazda universal joint:
