bpowa well, I would not do it for my jeep.. I would fill it to the fill hole and leave it. I did this to many trucks /cars and it works.. I jeep is no different.

jupiterboy ^ that's what I read. As soon as I got them both sealed back up I read to fill it 1/2 in below the fill hole. There is so much inconsistent info out there. How would you know when it was 1/2 below the fill hole anyway?

no offense.. but you have 2000+ post but it seems you dont know much or read anything at all about tech, gearing etc. I dont know if your joking.

4 bangers need higher gearing to compensate the lesser power of the i6.

so no your not screwed.

As for your origional question..

just fill the rear diff with diff fluid until it spills out of the fill hole and plug it back up.. it should not be more than 2- 2 1/2 quarts. just buy 3 quarts just incase.

4.10's will give lots of tourqey power but no mpg's. I have 3.07 gears in my jeep with 31x10.50 bfg ats and now this thing wouldnt pull a greasy string out of a cats butt and i have the 4.0

jupiterboy I just changed mine out with Amsoil Severe Gear.

AMSOIL - SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricant 75W-140 (SVO)

Their site has a pretty nice drill down by year with options and quantities even if you don't use their products.

Jerry Bransford This is an easier question than most would suspect. First, lockers don't change the kind of gear lube needed and most gear lubes already contain the friction modifier required by a clutch-based LSD like the Tracloc LSD is.

So really, all you need is a good GL-5 gear lube that, if you have a LSD in the rear axle, simply includes words to the effect 'compatible with limited slip differentials' or similar. If you don't have an LSD, you can still run a gear lube meant for an LSD just fine.

Viscosity wise, use lower viscosities for cooler conditions, higher viscosities for warmer conditions or for towing. The exact viscosity used is less important in the axles than it is in the engine. 75W-90 is pretty commonly used, but 70W-80 is fine too in cooler areas. 80W-120, 90W-140 etc. for warmer climates or for towing.

I'd also recommend a NON-synthetic gear lube for the axles. It is coming out that the ring & pinion gears run cooler in a non-synthetic gear lube which helps pull the heat out better than a synthetic gear lube does. Some axle manufacturers like Currie have gone so far as to require their customers continue using a non-synthetic GL-5 gear lube in their axles to maintain the factory warranty.

Diff fluid?

I'm sorry but I know this has been asked over and over. I have a 99, what kind of diff fluid and how much?
