There is a seal at the top of the column. Below that is the sensor section with a valve arrangement. The valve directs fluid under pressure through steel lines to a cylinder that has a rack gear which rotates the steering arms to the drag links going forward. I believe the seal is the only device keeping fluid in the column. It is not under great pressure, as it is in the return (discharge) side of the valving. It will leak, I have replaced them with a seal from Motion Industries after removing the old seal (25 years ago, so memory and crisp imagery are lacking). (difficult) I used a small ice pic to make a hole in the metal og the seal and used metal screws to pull it out up the shaft. (#6 deck screws might be best) I put the new seal on a polished up section of the shaft that was just a little ways away from the original wear groove. I is still not leaking. Good luck getting the steering wheel off. Jim
