CTA Manufacturing Transfer Case Mount Tool Kits: Precision for BMW AWD Drivetrains

When it comes to servicing the transfer case mount bushings on BMW all-wheel-drive vehicles, having the right tool is not just a convenience — it is a necessity. CTA Manufacturing has built a well-earned reputation since 1978 as a specialist in professional automotive specialty tools, and their transfer case mount tool kits are a prime example of that engineering focus applied to one of the more demanding jobs in European drivetrain service.

Why Transfer Case Mount Bushing Service Matters

The transfer case mount bushing is a critical rubber isolator that absorbs drivetrain vibration and maintains proper alignment of the transfer case within the chassis. On BMW xDrive and AWD platforms in particular, worn or failed mount bushings cause increased noise, vibration, and harshness (NVH) during acceleration, and can accelerate wear on surrounding drivetrain components. Replacing these bushings without the right tooling typically requires removing the entire transfer case — a labor-intensive process. CTA's kits are specifically designed to allow bushing removal and installation with the transfer case still in the vehicle, dramatically reducing service time.

CTA's Transfer Case Mount Tool Kit Lineup

CTA Manufacturing offers purpose-built kits covering multiple generations of BMW AWD hardware:

• CTA 8814 – BMW Transfer Case Bushing R&I Kit (3, 5, 7 Series): This comprehensive kit services BMW 1, 3, 5, 6, and 7 Series sedans as well as X1, X3, X5, and X6 SUVs from 2003–2015. It is compatible with BMW's ATC300/350/450 transfer cases found in E-Series and early F-Series AWD platforms. The kit includes a versatile set of press plates and adapters designed for various chassis and bushing configurations, and notably also covers select Rolls-Royce applications. It compares directly to BMW factory tools 221050, 221052/3, and 334465/6.
• CTA 8816 – BMW Transfer Case Bushing R&I Kit (X1, X3, X5 SUV): Specifically engineered for the X-Series — including the X1 (E84), X3 (E83), X5 (E53/E70), and X6 (E71) — this kit features a thrust-bearing press screw and alignment block for smoother operation and improved stability in tight spaces. It also fits shared AWD 3 Series and 5 Series configurations from 2006–2014, and compares to BMW factory tools 221051 and 221046.
• CTA 6544 – BMW B58 Transmission Bushing R/I Tool Kit: Designed for the modern G-Series platform, this kit targets BMW vehicles equipped with B58 engines and ATC13 transfer cases (2017–present). Applications include the G20 330i/M340i xDrive, G01 X3 M40i, G02 X4 M40i, G05 X5 xDrive40i/M50i, and more — making it an essential tool for shops servicing the latest generation of BMW xDrive SUVs and sedans.

What Sets CTA Apart in This Category

CTA Manufacturing draws on decades of OEM-level tooling knowledge to design these kits as direct alternatives to expensive BMW factory tools. Each kit in their transfer case mount tool kit lineup includes all necessary adapters for the target platform, is packaged in a durable blow-molded carrying case for organized storage, and is engineered to allow in-vehicle service — minimizing teardown time in a professional shop environment. The result is a factory-comparable solution at an independent shop price point, covering everything from early E-Series xDrive models all the way through the current G-Series lineup.
