Has anyone replaced the steering cables can you provide any guidance? The hoses that attached need to be replaced.
I'm not familiar with Symbol, a picture or more information would be helpful. If you mean hose then yes they are replaceable. Will likely have to have them made at a hydraulic hose shop to match the ones you remove. The systems that I'm familiar with are under pressure, the pressure must be released and either drain the oil or be prepared to catch it in a container to avoid a mess. Avoid getting any dirt in the system and the refill of the system can be tricky. It might be best to leave this job to an experienced mechanic. In my experience the pump ( steering wheel) is the problem child.
