Axles


From left to right is an '82 solid front axle, '85 solid front axle, and typical IFS axle and suspension.

Type	Year	Gearing	Width	Ring Gear Size	Shaft Size	Spline Count	Notes
Solid Front	1979-1985	3.90, 4.10, 4.30, 4.38	55 1/2"	8"	1 5/16"	30	Axle housings received more gusseting over the years.
Solid Rear	1979-1985	3.90, 4.10, 4.30, 4.38	55"	8"	1 5/16"	30	4.38s only available in 1980, 3.90s only available in 1981, 8" drums.
IFS Front	1986-1995	4.10, 4.30, 4.56, 4.88	58 1/2"	7.5"	1 1/8"	27	4.10s standard for manual transmissions, 4.30s standard for automatic transmissions.
Solid Rear	1986-1995	4.10, 4.30, 4.56, 4.88	58"-58 1/2"	8"	1 5/16"	30	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.
Solid Rear	1995-???	???	58 1/2"-60"	8"	1 5/16"	30	Tacoma axle uses the same brakes and third member as previous pickup axle, somewhere during Tacoma production the rear axle changed from 58 1/2" to 60".


From left to right is a leaf sprung solid rear axle, 4 cylinder (foreground) and V6 third members (background), and a 4Runner coil sprung solid rear axle.

Steering Boxes

Type	Year	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.


The push-pull box that comes stock on solid axle trucks is on the left. On the right is the more desirable IFS steering box.

Brakes

Year	Master Cylinder	Calipers	Rotors	Notes
1979-1985	13/16" Bore	Two Large Pistons, Two Small Pistons	Solid	8" rear drums.
1986-1995	13/16" Bore	Two Large Pistons, Two Small Pistons	12" Vented	15/16" and 7/8" master cylinders also reported to have been used, 10" rear drums.
1988-1995	1" Bore	Four Large Pistons	12" Vented	Larger brakes found on V6 trucks, 10" rear drums.


On the left is a rotor and caliper from a solid axle truck. in the middle is a rotor and caliper from a V6 powered IFS truck, and on the right is a solid axle equipped with IFS calipers and FJ-40 rotors.
