Toyota upgrades the 4Runner's ride and responsiveness by replacing the solid front axle with an independent front suspension (IFS).
The rear springs remained leaves. From mid-'86 to the end of 1987, there was an SR5 Turbo model.
This included, a turbocharged, EFI 22R. Some of these SR5s came with a digital dash package, upgraded interior, and beefed-up rear axle.
