On My 1968 the steering box had gone dry and resulted in some loose steering
I refilled the box with red line synthetic that leaked slowly. Every couple
of months I refilled. Currently the seals seemed to have expanded and there
is only the occasional droplet. While I am not of the opinion that
mechanical things heal themselves I do believe that seals can be
"re-hydrated". Worth a try. If you do keep checking the levels if it
maintains --saved a bunch of work.
