cristopherdelima New Member 4 Member For: 9y 10m 5d Posted 21/08/15 12:48 PM Share Posted 21/08/15 12:48 PM 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.

cristopherdelima New Member 4 Member For: 9y 10m 5d Posted 21/08/15 10:07 PM Author Share Posted 21/08/15 10:07 PM But the rod connecting the gearbox to the diff is moving. The clunking sound came from the rear it is like world war III is going inside the diff.. I would just like to know if its possible to change the diff ratio and change the whole diff? What are the best diff for this type of care?.Please help me..Sent from my iPhone using Tapatalk Link to comment https://www.fordxr6turbo.com/forum/topic/91029-help-my-ford-falcon-2007-bf-turbo-is-dying/#findComment-1559001 Share on other sites More sharing options...

f-wolf Member 897 Member For: 18y 2m 1d Gender: Male Location: ACT Posted 23/08/15 02:52 AM Share Posted 23/08/15 02:52 AM My CarBA MK2 Turbo, 2005, 6 speed manual.I just checked the info stored in the PCM of my Car...This is what I got re the Diff Ratio: http://s13.postimg.org/lt6kilit3/Diff_Ratio_2.jpgYou will have to replace your Diff with the same ratio of ( 3.23 )... Or you will / may get problems with your PCM getting wrong information from sensors... ABS and Speedo.
