Just got finished clocking my dana 300 and was wondering how much oil to run in it. I put 4 pints in it but was having trouble seeing what the level was. Will it take more. I tried puting a wire in the fill hole but the gears were in the way. Should I try to fill half way up the out put shaft. I want to flat tow the Jeep.
I assume TOM85CJ means the fill plug hole. If you do this you will end up spitting gear oil out the vent and cause excess drag in the t-case. 4 pints should be good, that's what I used. It puked out the vent for a short time and hasn't done it since.
72 CJ-5: 305 Chevy; SM420; D-300; 30/44 with 5.38's, Warn axles, and Detroits
