Do you need LSD on a jeep Rubicon?
The Rubicon does not have a clutch type LSD, no friction modifier required. Your Rubicon also has drain plugs in the diffs, so no need to pull the covers to change the fluid unless you just want to inspect the gears. Jeep specs the 140 for the Rubi rears. I also run it in the front just so I don’t have to have 2 different weights for it.
Do you need friction modifier for Rubicon diffs?
Rubicon diffs do not require a friction modifier, that’s only used if your LS has clutch plates which the Rubicon does not. As far as the Lube Locker, no sealant required. I use NAPA DynaLube 75w-90w, in both axels.
Can you use limited slip oil on a Rubicon?
Yes. I prefer to use 75W140 in the rear of my Rubicon even though I don’t tow. Edit: If the bottle of the 75W140 indicates “limited slip” you can still use it for a Rubicon which have open differentials. The rear uses a bit more than two, the front a bit less than two. It’s a pretty easy job so I’m sure you will do just fine.
