[SAVDOG]

And How Much Do Ya Fill It? Also What Is Good Grease To Use For The Outside Gears? Let Me Know Thanks.

Yeah I would make sure you check them for lube.Just be careful that the diff gasket doesn't split on disassembly. I use regular auto wheel bearing grease inside and a product called Transgel on the ring and pinion only because I get those for free!I have never had a lube related failure but I know most guys like to use silicon oil in theirs.Also make sure you use Loc-tight on the 4 ring gear screws and make sure they are tight.If you can replace those Phillips heads with hex type and while your there make sure the backlash is set correctly between the ring and pinion.

How Do Ya Set The Backlash Pine?

 

[SAVDOG]

Do Ya Pack The Diff Full Of The Auto Grease?

This should help you....and almost all the way with grease as the other half of diff needs some room in there,Dave

Cool diffs and great price as well.You want to check backlash anyways-this is the play between ring gear and pinion gear when assembled.You want to feel a little gap between the two while holding one still.Too much and pinion tooth will break,too little and both will wear fast.See that thread for more info or search diff here-lots of threads on it.

How Do Ya Get The Best Backlash In Your Experiences With Diffs?

 

[Pineapple]

It's just a matter of adding or removing shims between side bearing and diff case to move assembly closer to or away pinion gear.
