Product Details

TrakMotive FD-8378 is part of the AAR CV Axle Shaft line, built for front left service on select Ford Fusion and Lincoln MKZ models. This axle uses spline connections at both ends, a male inboard joint, and a conventional outboard joint to match the listed applications. The included axle nut features a 1.25 in. hex size and M22 x 1.5 thread specification, supporting a straightforward replacement during axle service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Restores driveline transfer when a worn axle shaft causes vibration or clicking
• Replaces a damaged CV boot or contaminated joint assembly
• Addresses axle noise during turns or acceleration
• Corrects driveline play from worn splines or joint wear
• Supports repair after axle seal or joint-related grease loss

Installation Notes

Verify vehicle year, model, and front left position before installation. Confirm spline count, axle nut thread size, and compressed length against the original part. ABS axles fit non-ABS applications unless otherwise noted, and this axle does not include an ABS tone ring. Inspect related components such as hub, seals, and suspension hardware during replacement to help prevent repeat driveline issues.
