Transfer case bearing Kit (ATC450)

You will typically hear a humming, whining, or grinding noise coming from the center of the vehicle that changes pitch with your speed. Other symptoms include vibrations during acceleration or a subtle jerking sensation when the system tries to distribute torque.

This kit is specifically designed for the ATC450 transfer case, which is commonly found in BMW X5 (E70 LCI) and X6 (E71) models produced between 2010 and 2013. We recommend checking the tag on your transfer case to confirm it says ‘ATC450’ before ordering.

Replacing the bearings is a cost-effective way to restore your drivetrain. As long as the internal gears and housing aren’t damaged, a high-quality bearing kit fixes the source of most noise and play issues, saving you thousands compared to a complete unit replacement.

These bearings provide critical support for the internal shafts. They ensure that torque is balanced and transmitted smoothly to the wheels. When they wear out, the shafts can misalign, leading to poor power delivery and potential damage to the internal chain or gears.

Yes, rebuilding a transfer case requires professional tools like a bearing press and snap ring pliers. Because of the precision required to balance torque transmission, we recommend having this kit installed by a qualified mechanic or transmission specialist.
