Pickup and 4Runner Transfer Cases
All V6 mini trucks use the chain drive tcase and have a 2.57 low range gear. Most
4 Cylinder mini trucks use a gear drive t/case with a 2.28 low range. However some 4 cyl trucks use
the V6 style chain drive case. The best way to find out what type you have is to look under your truck
and cound the bolts holding the rear cover in place.
If you have 7 bolts in the rear cover then you have the gear driven unit.
If you have 5 bolts holding the rear cover then you have the chain drive unit.
