Q: Is there a way to to fix a pin hole size leak in the power steering pressure hose without replacing the hose

The pinhole leak means that the internal lining of the hose is weak and/or deteriorating. As it deteriorates, rubber particles are liberated which run through the rest of the steering system causing other damage. Even if there were a technique to fix the hole (there isn’t), you wouldn’t want to employ it because the rest of the hose is not serviceable. Depending on the age of the vehicle, when the pressure hose is replaced, the return hose should be replaced as well and the system should be carefully examined for contamination (particulate matter in the fluid). If you desire that the hose(s) be replaced by a certified mechanic, please refer to YourMechanic’s power steering hose service page for a quote and scheduling. If you request that service, the responding certified mechanic will get this resolved, right at your location.
