Detailed Description

TrakMotive BM-86018 is a CV axle shaft engineered for the front left side of the BMW i8. The axle uses a long-male inboard joint, a flat spline outboard joint, and thermoplastic boots to support consistent driveline operation in the specified applications.

The BM-86018 part number is also the reference to use when matching this axle for service work on the BMW i8 front left position.

TrakMotive’s CV Axle Shaft line focuses on replacement driveline components for passenger vehicles, with this BM-86018 application built around the exact spline counts, compressed length, and joint configuration needed for the listed BMW i8 fitments. TrakMotive BM-86018 is the part number to verify when ordering for these vehicles.

What It Helps Address

• Clicking or popping from a worn front left CV joint
• Vibration during acceleration from axle wear
• Grease leakage from damaged CV boots
• Axle play caused by worn splines or joint components
• Driveline noise from a failing front axle assembly

Installation Notes and Tips

Confirm front left fitment by year, make, model, and axle configuration before installation. Verify the axle bolt uses a 17 mm hex size, M16x1.5 thread, and 83 mm length where applicable. This axle does not include an axle nut. ABS tone ring is not included, and the axle is listed with no ABS ring tooth count. Compare the original axle’s spline counts, compressed length, and joint style to BM-86018 before final assembly.
