10" rear drums, V6 and turbo applications used stronger third member with larger bearings and bigger third member, coil sprung 4Runner axles are 1/2" wider than pickup axles, factory 4.88s available in vehicles equipped with automatic transmissions starting in 1992, but the pinion is moved closer to the ring gear than on all the other 3rds. This makes it so they can use a standard thickness ring gear instead of an extra thick one. This "thin" 4.88 gear is only made by Toyota.

Notes

Push-Pull
|
1979-1985

Used on solid axle trucks. Displays quirky steering characteristics when used in lifted applications. J-arm and drag link are prone to breakage in extreme applications.
|
|
Crossover
|
1986-1995
|
Used on IFS trucks but ideal for crossover steering on solid axle equipped trucks.
