Yes, you need the friction modifier even if the oil you are using says it's for Limited Slip diffs.

I learned something today, thanks guys! I asked this exact question at the dealer a couple of months ago and got the opposite answer. Never trust the dealer eh? :wink:

Apparently you didn't read the entire thread. Look at posts 4, 7, and 8.

Sorry for being unclear, in post 2 I reported that you needed friction modifier even if the Gear Oil already had it, as that's what the Dealer told me when I asked. After, posts 4, 7, and 8 I reported that I learned something in post 12 where I quoted my own post 2, revoking my original statement in post 2. I am not sure I am the one who did not read all the posts. :bleh:
I have noticed, though, a lot of people don't read all the posts. |

According the the manual... if you have tack-lok, you have to add an additive, but it does not say what kind. I have the e-locks on both frount and back, so don't one need to have the addative for the lockers?

Don't quote me on this because im definitley not a mechanic but I don't think Rubicons require an additive. The Trac-Lok is a clutch type LSD and requires a friction modifier for the clutches, Tru-Lok which is used in your Rubi is gear driven so I dont think it would require an additive.

I was going to ask the same question. When I changed mine out the 1st time the Dealer Service Mang. told me I needed the additive. I'm still questioning myself on this issue. I'm soon due up for the next change of fluids....:thinking:
If some was added, it wouldn't hurt anything. |

No need for any doubt. The Rubicon with the Tru-Lok doesn't require an additive. If the dealer says it does, ask him why, since there are no slipping clutches in the differential.

Service manager? He doesn't turn wrenches, and usually knows extremely little about working on the vehicles. Shop foreman or a Technician is who you need to talk to. :thumbsup:
Btw it does not need additives, it's treated like a open differential. However, I am running Synthetic fluids, which never need a LSD additive anyway. |
all the writer was trying to do was charge you for the additive.. the tech, knowing a lot more than the wrtier, would not have added the additive (prob put it in his toolbox since you paid for it) and you would have left their thinking you now always need the additive.
