    How many quarts of rear oil should it take to fill a 14 blt ff, with a stock rear cover? I now how to check it, but I was just wondering how much should it take. I put in 4 quarts and it has not reached the axle bearings yet.
    Thanks Ed

    Put in as much as it will take. Put in the fill plug.

    Then jack up one side of the axle really high for 20 minutes. Switch, and do the same to the other side.

    Now top it up.

    You don't want to risk a dry bearing. Either you need to use an assembly lube - preferably one that will dissolve into the gear oil (i.e. not white grease). Or do the tippy-tippy action I described above. ;)

    Alright, looks like after I get back from turkey hunting tomorrow I'm jacking up the axle and adding more gear lube.

    I did what you said, instead I left it like that for about 5 hours each side. I'm up to 5 1/2 quarts already, I'll top it off tommorow morning.
    Thanks again. Ed

    According to ALLDATA, an '82 K20 14bff holds 5.4 pints of gear oil. With that said, mine took 3 quarts to reach the fill hole AFTER I tipped it both directions.

    Is this really true, that it can take 5+ quarts to fill a 14bff? My CUCV manual says 2.1 liters. Now I don't know how much to buy, and I was thinking of buying Mobil 1, which is $8 vs. $2.50 for Valvoline. :doah:
