I need to add lube to my BJ8 steering box. In the archives, there were several references to Penrite. Anyone have a comment? Where do I get it? How easy is it to put in? Do I have to drain the old stuff first (I hope not)? Something else besides Penrite? TIA. -- Mike MGTD (long gone) BN1 (long gone) BN2-100M (gone but in good hands) BJ8
