Trucks/4Runner equipped with rear wheel ABS have 2 high pressure power steering hoses. The hose not affected by the 3.4L swap connects the rear wheel ABS actuator to the steering gear. In some cases this hose is in poor condition or leaking, and should be replaced during the swap. This hose was developed to be a reasonably priced replacement for that need, and includes clamps to fasten the hose to the existing brackets.
This replacement HP power steering hose is installed between the Rear Wheel ABS actuator and the steering gear. This hose is not necessary to complete the 3.4L engine swap.
