Drivetrain Kit for 2012-2018 BMW xDrive Models - 4 Piece Direct Fit

In this review of the TRQ drivetrain kit for select 2012-2018 BMW xDrive models, the bottom line is straightforward: this 4 piece OE replacement kit is aimed at owners who need a complete front-end drivetrain refresh with a focus on fitment and long-term value. The kit includes two front CV axle assemblies and two front wheel bearing and hub assemblies, and it delivers a direct fit solution that replaces worn components without custom work. For garage DIYers and independent shops who prioritize correct fit and straightforward installation, this kit deserves consideration.

Key Features

• Complete 4 Piece Kit: Includes two front CV axle assemblies and two front wheel bearing and hub assemblies so both sides are replaced at once for balanced performance.
• Direct Fit OE Replacement: Designed to match factory geometry so installation typically requires no modification and restores correct drivetrain alignment.
• 100% New Components: Every part in the kit is new and precision machined to provide consistent tolerances and predictable service life.
• Upgraded Seals and Grease: Premium elastomer seals and moly greased internals are included to reduce early leakage and wear under normal operating conditions.
• Vehicle Specific Fitment: Built for select 2012-2018 BMW 528i, 535i, 535d and 640i xDrive applications with fitment guidance to ensure compatibility.

Who It's For

This kit is best for BMW owners and independent mechanics replacing front drivetrain components on compatible xDrive models who want a matched set for both sides. The all-in-one nature suits those addressing axle or hub failures at the same time and who prefer a direct fit OE replacement to avoid custom modifications.

It is less suitable for drivers who only need a single component replaced and prefer an OEM dealer part or those who require a factory warranty specific to dealer-installed parts. Also, if boot longevity under extreme off-road conditions is the primary concern, consider inspecting boots regularly after installation.
