1. Assess the Damage:
* How bad is it? Is it just slightly marred, or is the fitting completely rounded off? A small amount of damage might be fixable, while significant damage will require more drastic measures.
* Type of fitting: Is it a flare fitting, a banjo fitting, or something else? This dictates the repair approach.
2. Attempt Minor Repairs (Only if minimally stripped):
* Clean thoroughly: Remove any dirt or debris. Use a wire brush and compressed air if needed.
* High-strength thread locker: Apply a generous amount of a high-strength thread locker (like Loctite 648 or similar) to the fitting. This *might* provide enough grip to re-tighten the hose, but only if the damage is minimal.
* Vice grips (use with extreme caution): As a last resort for minor stripping, very carefully use vice grips to get a grip on the fitting. Be incredibly careful not to damage the fitting further or the gear itself. This is risky and often makes things worse.
3. More Involved Repairs (if significantly stripped):
* New fitting: This is often the best solution. You'll need to find a replacement fitting that matches your existing one. This might involve:
* Removing the old fitting: This may require special tools depending on the type of fitting. Often, a flare nut wrench is needed, but sometimes a specialized tool is required to remove stubborn or damaged fittings. Heat can help, but be cautious not to damage the power steering gear.
* Replacing the fitting: Once the old fitting is removed, carefully install the new fitting. Use thread sealant (specifically designed for power steering systems) to ensure a proper seal. Torque to the manufacturer's specifications.
* Helical insert (thread repair kit): If the threads in the power steering gear itself are stripped, a helical insert (also known as a Time-Sert or similar) can be installed. This requires a specialized tool kit and some mechanical aptitude. This is a more permanent repair than simply replacing the fitting.
* Replace the power steering gear: If the damage is too extensive or if you're uncomfortable attempting the other repairs, replacing the entire power steering gear is the most reliable solution, but it is the most expensive and time-consuming option.
Important Considerations:
* Safety: Power steering systems operate under high pressure. If you're not comfortable working with this system, it's best to take your vehicle to a qualified mechanic.
* Fluid: Power steering fluid is messy and harmful to the environment. Have appropriate containers ready to catch any spillage.
* Torque specifications: Always refer to your vehicle's repair manual for the correct torque specifications when tightening fittings. Over-tightening can easily damage the power steering gear.
Recommendation: If the fitting is significantly stripped, replacing the fitting is the best option. If the threads in the power steering gear itself are damaged, a helical insert is a good next step. Replacing the entire power steering gear is a last resort, though often the most reliable solution in the long run. If you're not comfortable with these repairs, take your vehicle to a qualified mechanic.
