How long do 4 wheel drive transfer cases last?

The lifespan of a four-wheel drive transfer case can vary widely depending on factors such as driving conditions, maintenance, and the vehicle's make and model. Generally, a well-maintained transfer case can last anywhere from 100,000 to 200,000 miles. However, off-road driving, towing, or neglecting regular maintenance can significantly shorten its lifespan. Regular fluid changes and addressing any issues promptly can help extend its longevity.
