    I would assume you could always put to little in but can you ever put to much oil in a differential? Would it just push out the breather tube?

    Re: Is it posible to put to much oil in a diff?

    I always fill mine up till it comes out the filler hole. Then hurry up and put the plug back in.

    Same way everyone I know does it.

    Actually since my rear dif is pointed up a little, I even jack up the rear to get a little more in.

    Yes , it is possible to put to much oil in a diff.
    No, it will not push out the breather tube enough to bring the oil to the proper level .

    In order to fill it up too much, you would have to be parked at a real extreme angle so that the tubes filled up. Just fill up to the filler hole and then squeese some more in and hurry up and put the plug in.

    Re: Is it posible to put to much oil in a diff?

    I have purposely overfilled the rear axle before, a 14bolt in a Blazer with the pinion angle set for a CV shaft really has some tip to it so I have put alittle extra it thru the vent tube with a rubber hose.If you look at the pinion bearing ht. and plug level you will feel better with having some extra oil in there.
    You may get alittle surprise when you go to check the diff. level a few months later after forgetting you put extra it![​IMG]

    Ok i just tried to get that plug out didnt work to well it was really stuck and didnt want to budge at all would it be possible for me to just put in 2-3 quarts in through the breather tube?

    Ok i know this may be getting old for you guys but I apreciate your patience. I tried pulling off that bolt and i finally got the ratchet to even turn but it didnt feel like i was making any progrees on the bolt like it was spinning in its place like it wasnt even coming out so i tried to drip the oil into the breather and i realized what you guys were saying it takes forever. Any ideas on what might be going on with that bolt or how i can get it out?

    Spray some PB Blaster or Liquid Wrench on the threads. Then get whatever fits properly in the plug head (I used a socket extension). Next attach a crappy ratchet to it an hit it with a small sledge hammer.

    Be carefull and make sure you have the ratchet set to loosen so you hit it the right way. Also make sure it isn't stripping out the bolt head.

    I actually replaced mine with one that has a square head on it that sticks out so any kind of wrench will work without stripping it.

    If you can't get the bolt out, you don't know how much oil is in it or how much to add. Plus 2-3 quarts is too much too add. The whole axle holds less than a gallon. 10-bolts barely hold more than 2 quarts.

    You want to get that bolt out sooner or later anyway. I think that you should focus your attention on that. I assume that you are working on the right bolt. It just takes a square 3/8" ratchet end (no socket) and it about 1" in diameter.

    But another question to everyone: what happens if you do overfill it? And why can't it be almost completely filled with oil?

    Ok I cant think of anything really that would go wrong if you filled it up with extra oil because when it expands it would just end up going up the breather tube but thats abut all i think would happen.

    Do you put more oil in the engine than is called for? Why not?

    You need to get that bolt out. Try some PB nutblaster on it. If that doesn't work, use a torch to heat it up some. I've had to do that before. That bolt is how you check to see if it's got oil in it without having to pop the diff cover. It is also how you make sure you don't over fill it. You've got axle seals and stuff that could start leaking if too much preasure builds up. Also, if you over fill it, it might spray oil thru the hose and on your exhaust, then you've got a nice fire or smoke show. When you get that bolt out, put some tephlon tape on the threads so you don't have to go thru this again.

    If worse comes to worse you could always remove the diff cover, drill a hole in it in proportion to the original filler hole and use an aftermarket rubberplug from Checker or Autozone. But I would say only as an afterthought if the original plug doesn't come out.

    That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>
