sway bar, 4wheel light, lockers problem

I have an 08 Rubicon. First the 4 wheel light was always on even in 2 wheel drive. Now it doesn't work at all. It does go into hi and low 4 wheel drive. Now the sway bar light won't stop flashing and I cannot get it to disconnect. I also can not get the lockers to work. Does the sway bar have to be disconnected to lock in the lockers? Please help me with these 3 issues. Part numbers would be great. I found a manual conversion to put on the sway bar as Jeep said they wanted $1500 for a new sway bar sensor. Any help will be greatly appreciated.

I had the same problems I sent it to the shop they put a new sway bar in. Thankfully under warrantee. And my front locker wouldn't stop flashing when I tried putting it in. They had to replace the plunger. All these electrical parts on a jeep are a bad idea. Especially seeing the sway bar module isn't waterproof. I had to bring it back after they replaced bc it still wasn't working so they replaced it again and gave me back the old module said it still works. Haven't tested it out yet though. I had them put dielectric grease on the circuits then seal it with that liquid gasket. Haven't had a problem since. As far as the 4wd light always being on Idk. Sorry.

Lockers only require you be in 4LO to engage. If they are not engaging, either you truly aren't in 4LO, or some part is broken. The swaybar only requires you be in 4WD under 17mph. If it isn't properly connecting or disconnecting, either you truly aren't in 4WD, are going over 17mph, or some part is broken.

Your 4WD light being always on even in 2WD - I would get to a shop and have them look at that. There may be an issue in the transmission or transfercase or the electronic stuff that drives them. It is highly possible this relates to BOTH of your other problems since both lockers and swaybar are 4WD or 4LO dependent. Something doesn't sound right. Or all of the problems could be unrelated - always possible I guess.

I would be thankful the swaybar froze connected at least. If it froze disconnected, street driving would be highly squirelly if not downright dangerous.

This reminds me to get to the dirt field and try everything once a month. The F & R lockers are the pain.

Yea. You always have to exercise the sensors and electronics. Make sure it's always working. Things were so much easier before the electrical components. Lol. And when you locked the hubs or disconnected the sway bars yourself you knew they were all set.

I have the disco links in the front so no big deal. There are times I think a good True-track style in the front diff wouldn't be a better way to go in the front. But I won't.
