Lucas oil in both diffs-changing ?'s

[Border411]

I bought some Lucas 80/90 oil for the rear diff of my 2004 4runner (4wd). My question is, can I use the same stuff in the front diff? I know it calls for 75w-90, but is it REALLY that much of a difference? I could just get 5 quarts of the same stuff and call it a day, rather than having a 1/2 quart left over from the front. Where do I get access to the front diff plugs anyways????

I read the website of bobtheoilguy.com or whatever it was, but personally, I have had great experiences with Lucas oil, and many of my friends who professionally drag race (extreme duty) will swear by it.

Anyways, another question is- can I just pump out the fluid through the top of the diff with a pump, or must I remove the bottom drain to get it out and to clean off any metal on the magnetic plug?

You can use it for the diffs and tranfer case. Use the drain plug and you will need the pump to put it back in. There are drain plug gaskets. You'll need 5 qts total.
