I am having both front and rear diff fluid changed. I read that you need an addtive for the rear if you have the Trac-Lok rear axle. I don't know if I have it. How do I tell? 2006 Renegade, 3.7l, Command Trac, ESP.

All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.
Any model year '06 KJ,regardless of when it was built(in '05 or '06) has ESP and traction control and no option for trashloc.Troy look at his build sheet..some 06 were built in late 05 etc...
I thought ESP/traction came on 07's and above..
Looks like he has an open diff...no mention of Trac-Lok.
And Shawn..ya many GL5 already have the limited slip friction modifier added, and yes that will work, but many still prefer to use the Chrysler Friction Modifier.

"FRONT DIFFERENTIAL: 80W-90, 75W-90, 75W-140
(change every 12,000-15,000 miles)
(2.6 pints)
REAR DIFFERENTIAL: 80W-90, 75W-90, 75W-140
(change every 12,000-15,000 miles)
(4.3 pints)"
What does that mean? You can use a range? Can you use the same fluid front and rear?
If you tow anything or oddroad thicker gear oil is better.They just want YOU to loose sleep ....
Unless You treat Your KJ so bad ( someone would say ... properly) no need for 75W-140, it's thick and would add additional 'drag', particularly in the cold season. Just IMHO.
PS : I use 80W/90,GL-5 dino, but I do get it cheap...
