mmmm interesting stuff i just orderered a rubicon 4dr and test drove all of them last saturday. Now my salesperson told me the rubicon had 4.10 and i noticed the diiference in drving the standrad unlimited back to back on the highyway did not like perfromance of diesel when tested back to back. Then he told me all the autos got the 4.10 which i did not test any autos only manuals. Also there is no lsd as standard but the new traction control system makes up for that. Seeing as we are towing and do a lot od 4wdring went for the Rubi with the lokkas and discos.
