    I bought a 14blt ff with 4.56 gears and a detroit locker about 2 months ago from a local military truck yard. It was obviously not used and in its original crate. The only dating I could find was on what used to be paper in the crate and I could make out a typed line ending in 198?. So my question is if this axle hasn't been used and has just been sitting in a crate for the last 20 to 25 years (assuming nothing crazy like at one time it was submerged in water or something) do I need to do anything to the internals (other than add gear oil)? I mean the bearings and everything, should I need to put new greese in them and if so is there a way to do it with out takeing everything apart? And I am sure this has been talked about before but what is a good oil for the diff? I have some Lucas gear lube left from something else I was working on would that be okay? Any help would be great. THANKS

    The bearings are prolly covered in cosmoline. Do a visual check for rust and fill it and weld some new perches on and run it!

    Pull the cover and make sure the bearings aren't rusted. If the bearings aren't rusted then just add some oil. I would install the rearend and then fill it with gear oil. Then I would rotate the diff by hand for a little while to get the oil coating on the gears, bearings, and down to the wheel bearings.

    It probably wouldn't be a bad idea to put a little grease or gear oil in the wheel bearings.
