05 Rubicon diff Oil
I want to change the diff oil in my 05 rubicon. Apparently it needs
to be changed every 12k miles. Sounds pretty lame to me but whatever. Anyway was thinking of putting in 75w140 synthetic. I assume this guy doesn't need any friction modifier? Should I consider just using the 80w90? This jeep is only used on pavement to get to the trail. It is not a daily driver at all. Suggestions? thanks all! |
Re: 05 Rubicon diff Oil
Rubis have lockers, but I don't know what kind. It will probably need
some sort of additive. Just a guess, though.

Re: 05 Rubicon diff Oil
I don't know anything about the Rubicon, except that a bunch of old
retired-looking coots shows up every summer in Silverton with them now, but needing to change diff fluid every 12k miles sounds like it has limited slip clutches in it. I would be very surprised in that case if it didn't need friction modifier. Do you know what kind of mechanicals it has in it?

Re: 05 Rubicon diff Oil
If it were me, I would split the difference on the mileage schedules. Halfway between severe and normal should be often enough. On my personal vehicles, and I have 4 that are 4x4 I look at the condition of the lube and change it when I notice a discoloration. As for lube, I have been using 85-140 synthetic for 15 years. My Cherokee has 240,000 miles and the Differentials are still going fine, not even so much as a pinion or axle seal problem. It is difficult to argue with that record... Good Luck, Bruce |
