another gear oil type question...
ok..so before anyone flames me for asking..i HAVE googled/searched this til my eyes bled.. i just wanna be sure and ask the pros...it's the LAST fluid change left for me under the ol J10...1974 with dana 44's...i found the tags on both diffs..so i know my gearing/etc..just was not sure on the REAR...mainly IF or how to tell if i have anything "weird" or sumthin..trac loc/towing rear etc...tags say 3.54..so i assume stock..but do u guys run any LSD additives in these? or just plain ol gear oil and shut my face?! thanks again guys!! hit me...(gotta say..i am pretty proud that my tranny and quadratrac show NO leaks..yet! and oil pan...just a SMALL drip...the "before" was the puddle style in driveway..but NO more!!
If you Google the id number on the tag it should tell you if you are open diff or not somtime there is another tag on the diff that will tell you bit they can be lost fall off etc on the old rigs like ours
Well you have to pull the cover to change the fluid. See what ya have then. If you do need lsd additive, it won't hurt it to run to the parts store with just gear lube, or get it and return if not needed, or jack it up and turn one tire and see which way the opposing tire turns

However, if you're not sure, you can go ahead and add LSD FM to the oil - if it's not needed, it won't cause you any trouble (I'd mix it in with all my stock - I had two rigs with OEM LSD rear, and three without. Same gear oil in all axles.) Use GL-5 spec oil in the axles - if you have a manual, you're probably going to want GL-3 so you don't dissolve the synchroniser rings (unless you get a "performance synthetic" GL-5 that specifically sez it's "Safe for use with Yellow Metal." If you get performance synthetic gear oil, yellow metal safe, with LSD FM premixed? Go ahead and use it in everything, she'll be right, mate! (LSD FM won't cause any trouble in the transmission - it's the added sulphur-based EP lubes in the mineral-based GL-5 oils that's a problem.)
