Does this transfer case come with the electric shift motor?
Yes, this complete transfer case assembly includes the electric shift motor and all internal components. The unit has been tested to ensure the electric shift mechanism operates properly for seamless 2WD to 4WD transitions.
How much does it cost to ship a transfer case?

Can I install this transfer case myself?
Transfer case installation requires lifting the vehicle, supporting the transmission, and working with driveshafts and electrical connections. While experienced DIY mechanics can handle this job, professional installation is recommended due to the complexity and weight of the component.
What maintenance does a BW44-45 transfer case require?
Regular transfer case fluid changes every 30,000-50,000 miles are essential for longevity. Use only the manufacturer-specified fluid type, and inspect for leaks periodically. Avoid extended highway driving in 4WD mode on dry pavement to prevent premature wear.
