Does anyone know how much gear oil goes in a 9"? I don't have an owners manual so i'm not really sure. Any help would be greatly appreciated. BTW going from 4.11's to 4.88's on 38's was well worth it!:rockon

Don't know offhand.. I just know you keep filling it until it comes out the fill hole and then close the filler hole..

And this may sound dumb, but put the additive in first, then fill it up with gear oil.


BTW - I love the skinny Boggers. I was gonna get a set for my truck but 38s would have hit my damn headers so I had to go smaller.

Well i guess the reason i asked the question is because i have oil coming out the ends of my axles. I thought maybe i might have overfilled it. But i guess i just have leaky axle seals. Are there inner axle seals on a 9"? I know there is on dana axles, but not for sure on the 9". BTW i think it took about 5 1/2 quarts to fill up my axle so you guys were close when you thought it took 5. I appreciate the info. Thanks:beer

There are only outter axle seals. You have to remove the axle and press the bearing off to replaced it, then press the bearing back on.
