I recently bought a Falcon BF 2007 Turbo and realized that the Rear Diff is dead. If changing the gear from Park to Reverse or any gear except neutral it can create a continuous clunking sound and it is not running at all. Is there any chance to change the diff with different ratio because the ratio of the dead diff was 3.23 LSD. Is there any difference between turbo diff to non-turbo diff?. what is the better diff ratio for just daily driving? Can I use any diffs from any ford falcon?. Thank you in advance in helping a newbie.
