by Contributing Writer; Updated June 12, 2017

Your Vehicles is equipped with state-of-the-art power steering control to make controlling your Vehicles nearly hands free. (nearly). The power steering pump provides pressurized fluid that drives the steering mechanism, giving you the feel of control without the work of turning the gears yourself. Your Vehicles has a pump line that connects the power steering pump to the steering gears and provides pressure to move the wheels back and forth. Occasionally this line can become damaged by road debris or by rubbing against other components and will need to be replaced.

 How to Replace a Power Steering Hose in a Dodge Dakota

Locate the power steering hoses on the front driver's side of your Dakota. The hoses run from the power steering pump to the steering rack below the engine.

Position an oil drain pan under the truck to catch any fluid that seeps out of the system when you remove the hoses. Locate the damaged hose and determine if it is a high-pressure or low-pressure hose. The high-pressure hose will have fittings on both ends and the low-pressure hose will have a fitting on one end with an open or bare end on the other. Select a flare nut wrench to fit the nut on the hose at the one end.

Remove the nut by turning the wrench counterclockwise until it is loose. Move to the opposite end of the hose and remove the nut there as well. If you are working on a low-pressure hose, the end at the steering pump may have a hose clamp and the hose will just slide onto a fitting on the pump. If this is the case, remove the clamp with a screwdriver and slide the hose off the pump.

Install the new hose, routing it the same way the original hose was, and insert the nut into the fitting on the steering rack. Tighten the nut with a flare nut wrench. Attach the nut at the pump end and tighten with a flare nut wrench. If this hose is the low-pressure or fluid return from the steering rack to the pump, you will just need to slide the pump end of the hose on to the fitting and install a hose clamp. Tighten the clamp with a screwdriver.

Add power steering fluid to the reservoir to bring the level to full. Start the truck and cycle the steering to remove the air from the system. Check the fluid level in the reservoir during this step and add fluid as needed to keep it full. Continue cycling the steering until it operates normally and does not make any noise.

Allow the fluid to drain until it is barely dripping.

Use your large crescent wrench by turning counterclockwise to loosen the top line nut until free of the threads. The line will not come loose yet.

Use your large crescent wrench to loose the bottom line nut by turning it counterclockwise until it is free of the threads. Push up slightly on the line and it will come free of the seat. Remove the old line.

Use your small crescent wrench turning clockwise to reinstall the drain plug. Use the shop towel to clean up any residual fluid.

Install the new line top first by placing the opening over the internal seat. Perform the same procedure with the bottom of the line at the same time. Be careful to line up the threads of both ends before tightening.

Use your large crescent wrench to tighten each line nut by turning clockwise a few threads at a time until they are both secure and snug. Do not over-tighten as this will damage the threads and cause leaks.
