Product Details

TrakMotive CV Axle Shaft BM-8727 is engineered for rear left BMW driveline replacement where the original axle has worn joints, damaged splines, or boot failure. The axle uses a bolt-on inboard shaft connection and a spline-style outboard connection, matching the listed BMW X1, 325xi, 330i, and 330xi applications. TrakMotive identifies this part as a new unit and notes that ABS axles fit non-ABS applications unless otherwise noted. This part cross-references BMW 33207605485 for the same application.

Common Repair Applications

• Clicking or popping from the rear axle area during turns
• Vibration or shudder under acceleration
• Grease leakage from a torn or cracked CV boot
• Excessive play in the rear left axle assembly
• Noise caused by worn CV joints or damaged splines

Installation Notes

Verify rear left fitment by year, model, and drivetrain before installation. Confirm axle nut thread size, hex size, and locking style against the original hardware, and inspect the hub, differential flange, and mating surfaces for wear before assembly. Because this axle includes an axle nut, compare the supplied nut to the vehicle’s original specification during service. For BMW X1 and 2006 BMW 325xi, 330i, and 330xi applications, follow factory torque procedures and alignment checks after installation.
