Front and Read Diff Level ?

Justintoxicated · 04-20-2008, 10:46 PM

I drained my rear diff today and when I filled it up it only took 2.0 quarts.
I had written down that 2.1 was the correct amount but it slightly drained out of the fill hole with only 2 quarts.

Is this alright?

Front diff I put about ~1.8 in
I had written down someplace that it only takes 1.5. It was not spilling out when I stopped, however when I put my pinky in the whole and pulled it out my finger had oil on it so I would assume it is full.

Is this alright?

I taped a pplastic bottle to my front diff overflow hose. Last time I filled it alot of oil came out the overflow. last time I filled it until it was pouring out though.

Neither diff was hot when I changed, I didn't want to spend $$ wasting as to warm it up. I just took it around the block before I replaced the oil.

BTW, the amsoil in the front diff still looked brand new with roughly 25k on it. I don't even know if it was necessary to replace the oil in the front diff, or if I really should do 30k intervals with this oil (Can I go more?), it looked just like new oil! The rear had the factory oil in it with over 10k on it and it was smelly and discolored a bit. I was changing it early because of break in.

Thanks in advance.

Was the ground level? If 2 quarts is all it took and the pinky came out wet, I would say it's full. Did you have the rear Diff replaced. I noticed the mileage difference between the two. I will bet changing mine out here soon too. Did you do the transfer case?

it was street parked so no not perfectly level but should not be too bad. Yea I did the transfer case a couple weeks ago. The amsoil for the front diff was backordered for a couple days and this was the soonest I could get to the diffs.

Are you using Severe Gear? I read in some Amsoil literature that you could leave it for 100K provided you weren't towing / hauling on a regular basis. I don't know if I would go that long, but I think 30 - 50K is probably doable.

Your level sounds correct, provided you were on level ground. I filled my front to this amount, which is basically what the service manual states (first portion of your pinky touching the oil - very precise. LOL). Anyway, I think your okay.
