Overview
The Eaton Toyota 7.5 inch IFS ELocker4 Locking Differential, part number 14220-1, is an electronic selectable locker for a Toyota 7.5-inch independent front suspension axle with 27 splines. It is designed for traction on demand.
A switch takes the driver from open to fully locked and back again. The four pinion gear design adds strength and capability for more demanding vehicles. It engages in 0.14 seconds, and it is a front axle position.
Key features
- Electronic selectable locker, operated by a switch
- Four pinion gear design for added strength
- Fastest engagement listed by Eaton, at 0.14 seconds
- Open to fully locked and back again on demand
- 27 spline front axle
Fitting an IFS locker
On an independent front suspension axle, the locker sits between two drive shafts that also turn the steering knuckles. Because the front wheels steer, the driveline and CV joints work through a wider range of angles than on a solid axle. A locker adds torque at both front wheels, so the joints and steering parts should be in good condition before installation.
The switch and wiring run through the engine bay and underbody, where heat, water and debris can reach them. Route the harness with clear separation from moving parts and secure every connection. Recheck the gear oil level after the first drives.
- Inspect CV joints before installing
- Route the harness away from moving parts
- Check the switch after trail use
