I had the same problem with my 2wd steering rack a few years ago, it was the original one fitted in 1990 and was leaking fluid from various seals etc. There is really only one solution get a re-conditioned one. There were other things worn as well on mine and when the new one was fitted it made a big difference to how my car steers. Not sure if you have somewhere in Malta where you can get a re-con one but there are a couple of places here in the UK.
