is that going to be enough for daily driving no one mentioned how much of a pain in the ass gettin the fluid in was the car was jacked up on the left side i got as much as i could in the rest i spilled any help would be appreciated.

 

Thats about right. 0.7-0.9 of a quart is what it will hold. Don't overfill it too much.

 

Jack up the car and keep it on ground level. Once it starts leaking out from the Fill hole, your good.

If you don't have 4 jacks, use 2 jacks in the rear and jack up the front so the car can stay leveled.

 

I usually put it a full quart. I was surprised that one dealership fills a new diff before installing to the very top putting in more lube than you could ever use... unless you stood the car on its nose.

 

ok second question is i used royal purple it was like 16 buck a quart is it ok to mix different brands just to top it off? i dont want to pay another 16 for less than a quarter pint.

 

fill to spill (0.78 quart total, 2/3 mobile1 75w90 with 1/3 lucas)...

 

what lol

 

Use the same fluid. When you are talking about a $20-$30K car, $16 is nothing.

 

more like 11 but i see where your comin from at least ile have some readily available if i need it in the future

 

fill to spill = fill it until it runs out the fill hole, you want the maximum that can be held by the assembly. i have a cocktail blend of mobile 75w90 ($9) and lucas ($9). the mobile is the main differential fluid but the lucas is there to stick on the gears and quiet the differential. s2kpuddydad recommended throwing in a little lucas. my 4.77s are smooth and quiet...
