97 Differential Fluid

[camlex]

Hello,

Please review attached picture. There is one drain plug for differential fluid. then one fill plug and at same level two other plug.

Questions:

1. What reason

2. Can you use one out of those two plug for fill differential fluid (Same as trans. DEX-III) Easy to put tube from top

(99 and UP model has differential drain plug but fill from top through dip stick) correct me if i am wrong.

Thanks,

Weird that they have three plugs there, the one looks a little higher than the other two. I looked it up in my manual, but there is no explaination.

Thanks george,

Top one is easy to open from top and has room to work, should i use that to fill, capacity for Diff. fluid is 0.9 qt.

may be 1/2" above fill plug.

Thanks,

I opened top bolt (12mm). I can see transmission fluid. i lost 10-12 drop. its telling me that fill plug and top bolts at the same level.

George, i am thinking these are for may be bleed purpose.

How many miles you should change differential fluid?

Thanks,

Not sure, I don't see that on the service interval. I would probably do it at the same time I serviced the trans.

So, which once was the Fill hole? and do you happen to remember the sizes and type for fill and drain?. (socket/allen)
