Will a 1997 Chevy truck transfer case fit 1999 Tahoe?

It's unlikely a 1997 Chevy truck transfer case will fit a 1999 Tahoe directly. While both are GM vehicles, the specific transfer case used depends on the truck's configuration (engine size, drivetrain options, etc.) and the Tahoe's as well. Even if they appear similar, the bolt patterns, output shaft lengths, and input shaft dimensions might differ, preventing a simple swap.

To be certain, you need to:

1. Identify the exact transfer case model: Find the casting numbers on the transfer case of *both* the truck and the Tahoe. These numbers will allow you to cross-reference with parts databases or a GM parts specialist.

2. Compare specifications: Once you have the model numbers, compare the specifications of the two transfer cases to ensure compatibility. This includes input and output shaft dimensions, bolt patterns, and overall dimensions.

Simply having the same year or even the same GM platform isn't sufficient to guarantee compatibility. You need to verify the specific transfer case models.
