I just purchase a Rubicon Express 3.5 inch Superflex kit for my jk. My guy installing is coming up on a problem. just wanted to know if this has happened to anyone else.

Basically he told me that the rear differential keeps locking. Hes adjusted the suspension and everything.

any help would be amazing.

 

I'm not sure how a suspension lift could possibly affect your Rubi's locker...something I'd be more inclined to check would be to make sure the e-brake hasn't been limited out and engaging partially. Is the locker light coming on??

 

i have no clue, all he told me was that the rear diff isnt locking

 

Isn't ?? Your title says keeps locking, and you said it keeps locking in the first post. If it's an isn't locking problem, I'd say the two wires leading to the diff to actuate it may be damaged and to check them.

 

im sorry i had a typo- it is locking

 

Just to clarify. Your profile doesn't actually say that you have a rubicon, so are we talking about the stock rubicon e-locker? A factory limited slip? Open, and something else is going on? (yes, I am assuming a rubi elocker, just wanting to make sure... )

 

we fixed the problem.

looks like in the near future i have to replace my rear driveshaft and upgrade to a better one.

 

I think there was a communication break-down somewhere along the way.
