Hey guys

I have a 2001 automatic transmission XJ ( U.S. specification )
I imported the car from the USA

And the rear differential runs only on 1 wheel

The Asia spec XJ have a different differential from the U.S. spec
Asia spec differential runs with 2 tyres both with same power
The Asia spec differentials comes with clutches

The U.S. dont ! So it runs only with 1 wheel



What I'm planing now is to change my differential with the Asia spec differential that comes with clutches so that it runs with both wheels

What I have now is I think 39/11 no clutches


So will I have to change the ring and pinion?? cause I upgraded to 31" BF all terrain tyers

What I have is this differential now
