You'd need to replace several major components:
* Front Differential: This needs to be completely removed. You can't just disconnect the driveshafts; the front differential is a major part of the 4x4 system.
* Driveshafts: Both front driveshafts need to be removed.
* Transfer Case: The transfer case, which splits power between the front and rear axles, needs to be removed or replaced with a 2WD unit (finding a suitable replacement might be difficult).
* Front Axle Components: Beyond the differential, various related components like axle shafts, hubs, brakes, etc. would need to be dealt with – either removed entirely or replaced with 2WD-specific parts.
* Control System: The 4x4 system’s control linkages and possibly the vacuum or electronic system would need to be removed.
* Wiring and Vacuum Lines: Wiring harnesses and vacuum lines related to the 4x4 system would need to be disconnected and potentially modified.
Why it's impractical:
* Cost: Sourcing replacement parts (especially a 2WD transfer case) and paying for labor to do the extensive disassembly, modification, and reassembly would be very expensive. It's likely to surpass the value of the vehicle.
* Complexity: This is a serious mechanical project requiring significant automotive expertise. Unless you have extensive mechanical experience and the proper tools, attempting this would be extremely challenging.
* Availability of Parts: Finding 2WD-specific parts for a 1995 Suburban might be challenging, especially if you don't have access to a junkyard with a good selection of older vehicles.
In short: Selling your 4x4 Suburban and buying a 2WD model would be a far more sensible and economical solution. The conversion is far too complex and expensive to be worthwhile.
