ABS Light Illuminated and Rear Axle Leaking on Toyota 4Runner

Problem overview

Owners frequently complain of leaking rear axle seals, which leaves gear oil on the inside of the rear tires and on the ground near the wheels.

The leaky seals allow gear oil to drip onto the rear brakes, and anti-lock brake (ABS) speed sensors causing poor braking and illumination of the ABS and Traction Control lights.

The correction is to replace the axle shaft seals, and clean all brake components in the rear of the vehicle. Replacement of wheel speed sensors has been necessary if the issue was unresolved for extended periods of time.
