Years ago I built a willys truck with a sm420 trans and a.dana18 t case with a warn overdrive. Its a plow truck used.at my grandfathers property. When it was cold l mean really cold the trans and case were hard to use. After a few years the 18 case got loud and I tore it down and put new bearings in. At the same time I put castrol syntec 15-50 motor oil in the gear boxes. Since then it has worked great even at 25 below and nothing weird is going on even with the trouble some dana 18 intermediate shaft bearings. Just thought i would share. Thanks for sharing, as I said I am looking for advice to help decide what to use. Novak also mentions the use of 50 motor oil. Mark | | |
