BMW E66 735Li 745Li N62 Automatic Gearbox Drive Prop Shaft Propshaft 7513531

The BMW E66 735Li / 745Li Automatic Transmission Driveshaft is an original drivetrain component designed for the 7 Series sedans with an N62 engine and automatic transmission. As part of the Cardan Joints group, it ensures a stable connection between the gearbox and the rear axle, contributing to smooth acceleration and comfortable drivetrain operation. A used OEM component is a sensible choice for professional repairs when you want to maintain the factory driving characteristics.

Application and Compatibility

The presented driveshaft is designed for the BMW 7 Series E66 735Li and 745Li models equipped with the N62 engine and automatic transmission. The design has been specifically developed for the long wheelbase (Li) body, taking into account the torque characteristics of the N62 unit and the specifics of the automatic transmission.

Thanks to its factory origin, the component retains the correct mounting points, geometry, and fit with standard supports and joints, which facilitates installation and reduces the risk of improper alignment with other drivetrain components.

Construction and Role in the Drivetrain

The driveshaft from the Cardan Joints group is responsible for transferring torque from the automatic transmission to the rear axle, while simultaneously compensating for suspension position changes and vibrations generated during driving. In practice, this means:

• a stable connection between the gearbox and the rear differential,
• reduction of vibrations and noise in the cabin at typical highway speeds,
• proper cooperation with supports and flexible joints,
• maintenance of proper drivetrain operation under load changes.

A well-chosen driveshaft is crucial for driving comfort, smooth acceleration, and the durability of other drivetrain components.

Designed for Automatic Transmission

The component has been designed to work with an automatic transmission, which means appropriately selected length, joint operating characteristics, and compatibility with the mounting flanges of the automatic transmission used in the E66. In practice:

• it ensures smooth torque transfer during gear changes,
• it is adapted to the operating characteristics of the torque converter,
• it reduces the risk of undesirable vibrations typical of incorrectly selected shafts.

This preserves the factory drivetrain operation, which is particularly important in a luxury sedan like the BMW 7 Series.

Condition, Origin, and Benefits of Installation

The offered driveshaft is an original BMW part from the aftermarket. A used OEM component allows you to maintain compliance with factory specifications while reducing repair costs compared to a new part. This is a good solution when:

• you want to eliminate vibrations and knocking coming from the center tunnel area,
• you plan to replace a worn shaft after a joint or support failure,
• you want to maintain the original driving characteristics and comfort.

Installing an original driveshaft contributes to the longer lifespan of other drivetrain components, such as flexible joints, supports, or the differential, as they operate under conditions intended by the manufacturer.

Drivetrain Extension and Additional Materials
