Differential change to amsoil

[TheBlueWave]

I did a search on this, turned up nothing. I plan on changing out my differential oil, and am going to use amsoil synthetics. While browsing for products, I came across a severe gear 75W-110 viscosity rating. Has anyone used this? I have seen people use severe gear 75W-90. It says it can replace competitor's 75W-90 so I am wondering if anyone knows if this would be good or bad to use.
Thanks.

stick with the Amsoil severe gear 75w-90

Almost done!

Well, I put severe gear in the rear diff and transfer case (transfer case oil looked very good, rear diff was black) but broke my 10mm hex socket on the front diff drain plug, sheared it right off, and didn't have another one (y would I) so the front diff will have to wait. What a PITA. I also need another grease gun to get the u-joints (non moly grease).

But besides the rant I am asking for some advice. My hex socket was a craftsman 3/8" drive, should I go with 1/2" drive? A different brand? Also, does anyone know the total number of grease fittings for each type of grease used and the locations? I know I found many of them but I know I missed some too. :bash:

Check out this thread. There's three per drive shaft, one for the slip yoke and two for the u-joints. The 4th gen doesn't have a double-cardan.

As for tools, you can try Husky from Home Depot which also has a life time warranty. Otherwise, it would be tools used by mechanics like Snap-On or MAC.

If your having trouble getting the bolt out make sure your using a 6 point socket. The 6 point will have more surface area on the head than a 12 point will.

I learned that lesson the hard way a long time ago my friend. This bolt uses a hex head, like one you would use a hex key (allen wrench or key) on. In this case, the hex key is turned by a ratchet.

The owners manual file shows a double cardan joint, but if I don't see it, I'm takin your word for it.
