Toyota Land Cruiser
Usage: Toyota Land Cruiser
Notes: Many variances in case design and internals. Low range ratios include 2.31:1 (pre '74), 1.99:1 (1974), 1.96:1 ('75-'80), 2.28:1 ('80 -'83/'84), 1.96:1 ('83 and up). Aluminum one-piece case version uses both 10-spline (early) and 16-spline input shafts. Strongest models are 1980 and up units with two-piece split aluminum case with 19-spline input shaft.
Weaknesses: Pre-1980 aluminum case is weak and prone to failure. Low gear range is lacking.
Strengths: Aftermarket cases of greater strength are available.
This Suzuki transfer case...
This Suzuki transfer case is shown with a Mighty Kong mount available from Trail Tough. A rear driveshaft disconnect is also in place. Numerous Low gear options are also available for Suzuki 'cases.
Suzuki Samurai
Usage: Suzuki Samurai
Notes: Minor changes to overall design through years. Low gear ratio of 2.268:1 for all U.S. models. Gear-driven unit uses cast-aluminum three-piece case with 26-spline input shaft. Outputs are passenger side at front and rear.
Weaknesses: Mounts are weak and prone to failure. Low gear range is lacking. Case strength is questionable when lower gears are installed.
Strengths: Parts availability. When outfit properly the Suzuki T-case performs rather well in Suzuki vehicles.
Nissan TX-10
Usage: 1986-2004 Nissan truck and Xterra, 1988-1995 Pathfinder.
Notes: Part-time, chain-driven two-speed transfer case, three-piece aluminum case, 30-spline input shaft (four-cylinder trucks use a 22-spline input shaft), 2.625:1 Low gear ratio, 32:1 crawl ratio. TX-10 mated to automatic transmission featured an oil sill around the input shaft to maintain lubrication. Differences in wiring harnesses and speedo sensors exist through years of use. Most 'cases are interchangeable but can only swap a T-case behind an auto transmission with another auto trans T-case due to oil sill.
Weaknesses: Low gear range is lacking, lower gears may weaken case assembly
Strengths: Versatility and parts availability
