Hey Guys - for those of you that are running synthetic gear lube in your front and rear end gears, what brand do you prefer? I read my owners manual but it says you never have to change it - and doesn't even give a refill quantity. The only thing it says it that you have to use a "friction modifier" in the rear one due to having "limited slip". My questions are: What brand and weight synthetic lube for the front (no limited slip) and what brand to use in the rear (needs friction modifier for limited slip)??? Also, how much does it take each to fill the front and rear diffs? How about the transfer case...what do you use in it??

Most synthetic gear lubes already have the friction modifier mixed in for the limited slip differentials. I've always used Amsoil....in all my vehicles. Haven't had a problem yet.

 

Thanks for the info! Website you linked me to looks like one I will be using!
