what happens when u put a whole quart? dumb me, was just putting away until i notice the whole quart was pretty much empty. puddymod said something will break if i overflow it. i used 75w140 amsoil. it is hard to tell if it is dripping out because it is so thick! what can i do?

 

Jack up the car on a level surface and open up the fill hole, let any excess drip out.

 

your andrey right?

well i did try to drive around to warm up the fluid so it would flow easier. but when i opened the fill bolt it didn't really come out.

 

Yep I'm Andrey.

Then I think you're fine. I mean it takes like .89 quarts, almost a full bottle. Unless you literally got every drop out of the bottle, it sounds like you'll be fine.

 

Just drive it to a quick lube place and drive over their pit. Have them loosen the fill bolt until it stops draining, then re-tighten. Drive away and be happy!

 

I agree with spets. But if you that worry, change fluid again. Make sure car is even on ground or on jack stand. Should have little bit left on bottle after you done.

 

car should be level.... and yes, over filling can cause failure in the diff.

 

I have done multiple diff fluid changes but I usually used 75w90. And it is easy to tell when the fluid drips out and of course I always use 4 jack stands to keep it level. But puddymod told me to use 75w110. it is way thicker. It makes it hard to tell if it is trickling out or what not because of it viscosity.

 

how so, they both have the same starting viscosity, or is that another old wives tale?

and to INDYMAC, im surprised you would say such a thing, its threads like this that were born out of people trying to avoiding quik lube type places Ill take it as a joke

 

It was no joke, if someone who does their own differential service has no idea whether he put too much fluid in after he is done. Are you saying he should just keep driving his car, in spite of his incompetence?

I'd take my chances with a quick lube servicing my equipment over someone who can't even get his car jacked up properly to get the correct amount of fluid in the equipment. I realize that you and probably others here would choose differently and I respect your opinions.
