A Guide to Fixing the Power Steering Hose O-Ring
Are you suffering from fluid leakage from the cap of your power steering reservoir? That might be an issue related to O-ring problems. In short, your power steering hose O-ring might be cracked, loose, or otherwise damaged. Having no leakage is important in ensuring that your power steering remains operation. This special feature allows you to remove the need to apply more force into your steering in order to execute hairpin turns while you're driving on the road, giving you the comfort of easy torque even when traveling at slow speeds. With that said, here's what you need to do to repair your hose O-ring and other related components for your power steering assembly.
Difficulty Level: Moderate
What You'll Need
- Shop rags
- Ratchet and socket
- Phillips screwdriver
- Floor jack and two jack stands
Step 1: Park your car somewhere safe. Open the hood of your car. Find the power steering system on your car (that is, part of your steering column assembly) by following parts of it through the firewall on your car's windshield side.
Step 2: Follow the indicators of your steering column's presence inside your car (like its components and their respective mounts) all the way to the wheel hoses and assemblies connected to the reservoir and pump of your power steering system.
Step 3: Clean the dirty and moist components of your steering system. Use shop rags to check if the leak source is something other than your O-ring. Start your engine, rotate your steering wheel from left to right to increase pressure in the system.
Step 4: Turn the engine off and check the system from the engine compartment with a flashlight. There are times when you need to way a couple of days for the leak to show itself.
Step 5: Look for possible cracks on your power steering pump. If the pump case is leaking fluid, then the case might be replaced. Some pumps have internal seals that should be replaced as required. Search the reservoir to ensure it's in good condition.
Step 6: Go to the O-rings sealing the connection between the hoses and the assembly (for the control valve and reservoir) and check the extent of their damage. If they're considerably damaged, lubricate the O-rings for good measure.
Step 7: Position the new O-ring in the groove without it covering the pressure bypass hole. Use a special tool in order to ensure proper pulley mounting on the new pump's driveshaft. Fix the pulley alignment to its exact placement with a laser alignment tool.
Step 8: Make sure the fittings on the hoses are tight by tightening the clamps with a ratchet and socket or Phillips screwdriver, depending on the type of clamp or fitting in your car. If there's a cut close at the end of your hose, you should cut that damaged part and reconnect the hose to your component.
Step 9: Inspect the metal lines that connect various components to the steering gear assembly for damage. Replace the lines if necessary. Check the rubber boots between the arms linking the assembly to the wheels and the steering gear assembly.
Step 10: If fluid is leaking on the other end, you might need to change your seals as well. Finally, raise your vehicle's front end with a floor jack then support it with jack stands. Check closely the steering gear assembly from this position.
