I have been having increasing steering problems. The problems started out intermittent where I would spin the wheel a few times and then the steering would engage, to taking more spins, to finally hardly steering at all. This happened over a the course of months. All the hoses under the steering wheel look fine, so I am thinking its the seals in the steering cylinder. Do I try to replace the seals, buy a new cylinder, or what other advice might people have?
