AISIN Manual Locking Hub | 4WD (1984-95 4Runner / 1979-95 Pickup)

AISIN Manual Locking Hub

For 1984–1995 Toyota 4Runner 4WD and 1979–1995 Toyota Pickup 4WD

Overview

The AISIN Manual Locking Hub restores factory-style manual FREE / LOCK operation at the front wheels of classic Toyota 4WD trucks and SUVs. Locking the hubs mechanically connects the front wheels to the front axle shafts for four-wheel-drive operation; setting them to FREE disengages that connection for normal two-wheel-drive driving.

Two axle-specific fitments cover factory solid-front-axle and factory IFS vehicles. Choose the fitment that matches the vehicle's front axle configuration, then select a Single hub or a Pair (Complete Front Set).

Key Features

• Manual FREE / LOCK operation for direct front-hub engagement and disengagement
• Two axle-specific fitments covering factory solid-front-axle and IFS Toyota 4WD vehicles
• 30-spline solid-axle configuration for 1979–1985 applications listed below
• 26-spline IFS configuration for 1986–1995 applications listed below
• Front application for Toyota Pickup and 4Runner 4WD models
• Available as a Single hub or Pair (Complete Front Set)

Manual Hub Operation

Set both front hubs to LOCK before using four-wheel drive. Set both hubs to FREE when the front axle does not need to be mechanically coupled to the front wheels.
