Saturday my 03 1500 hemi 4x4 goes in for its 15000 mile service. I have the 3.92 anti spin rear gear. Has there been many problems with this set up. I also want to switch fluids to synthetic. Do stealerships use mobil 1 or something else? Also is the 3.92 anti spin the same thing as posi????

Nope Most Dealerships Use Bulk Oil For Oil Changes That Comes From................ Hell Who Knows!!!. As Far As The Rear End, The Dealer Will Use Mopar Fluids.

2005 manual now calls for SYNTHETIC MOPAR and LSD additive for the rears

I have question possibly a stupid one but here goes,do you have to add friction modifier along with the oil additive or is it the same. I remember that when i did a gears swap on a mustang the friction modifier was dark green,and the oil additive is yellowish in color.

Dana Limited Slip = yes.

Armerican Axle LSD = no (but it doesn't hurt to add).
