so i changed the diff oil change on my 06 g35 coupe. The problem is...my car wasnt level when i filled in the diff. the rear wheels were raised.
Before even i was done with first bottle,1qt, it started to leak... wth..
i hope it's because the car wasn't raised level. So i just kept on pumping. i fnished with the first bottle even though it leaked. For the 2nd bottle, i didn't put much in. i just kept on pumping untill i saw it leaking.
After that, i lowered the car and started the engine. Idle it for 5~10 mins and smoke started to come out of the muffler. i'm not sure the smoke is from just the car warming up or somethin wrong with the diff- like i put in too much fluid..

HELP ME

 

That wouldn't cause smoke to come out your mufflers on Les you spilled oil somewhere on your exaust.

 

i didn't spill oil IN the exhaust. but i think i ve got alittle bit on the exhust pipe.
Do u know what i have to do after changing oil? i heard that not to press on the gas....

 

If you were using a 1qt bottle it should not have overflowed after just one; it should take about 1.5 qts. Did you drain ALL of the gear lube out of the bottom drain of the diff? Where was it 'leaking' from? I'm having a hard time picturing what you did here.

With the car level, if you take the top lug out you should be able to crook a finger inside & downward and touch clean lube. If you've done it properly, you can just drive the car normally, not sure where you heard the 'don't press on the gas' bit.

 

i think it overflowed b4 i finished first bottle because it wasn't leveled. i drained it from the drain plug. i took out the fill pulg b4 unscrewed the drain plug. i drained untill it dropped drops not in a line. Never mind about leaking i meant overflowing.

 

Sounds like you're fine, but if it were me I'd do the little check I suggested to make sure the level is up close to the fill plug.

This is why I like having jackstands, you can get your car high enough to work under it and still keep things level. Though unless the back was REALLY high, it shouldn't have made a huge difference.

 

when the rear part was jacked up, the fill plug started to overflow after 1 bottle and lil bit of 2nd one. If i were to check the fill plug after jacking up the rear part again, then it would b same as i checked after putting in oil. So that means i have to check without the car jacked up.

what happens if i put litle oil and too much oil?

 

HAHA....OMG! Who's on first....?
Gary

 

If he had the rear end of the car up in the air and it wasn't level then he had half a quart left in there and it didn't drain properly. The drain plug is toward the back of the vehicle. I'd do it over and try to level t he car this time.

 

how am i suppose to raise it leveled with 2 jack stands, 1 hydraulic lift and 1 for changing spare tires?

 

Jack up the front, put it on solid wooden blocks, jack up the rear, put it on jackstands. Or buy 2 more jackstands, they're not too expensive. Or Rhino Ramps if your car is not too low to drive up on them. Lots of options.

 

i got no solid blocks..
is there a jacking spot on the center of rear side?
From a pic, seems like it's the diff area..

 

Mine wasnt level, all I did was I backed my car up on rhino ramps, and I know I did everything right because almost exactly when I reached 1.5q, fluid started coming out of the fill hole

 

Under the diff, yes.

 

o man...i guess i'll use 2 jack stands for the front and hydraulic lift the diff...without jack stand!!lol
