Hi I want to change the rear differential in my sedan. I found several that are exact matches, but I was wondering if the coupe and sedan rear differential are the same? Found a better price on a coupe just wanted to know if they were the same in exterior dimension and mounting. I have g37 11 sedan AT and the diff is from a 08 g37s AT. Thanks in advance for any help.

 

do you have an Awd? the gearing on the 08 coupes is different (I.e. makes it incompatible with the 7at front differentials).

Also there are three different pinion flanges used on the different diffs... and they need to be changed if you don't have the same one.

do a search on here there are many many threads on here about the differences.

 

No it is not an AWD. I know about the flanges I read somewhere that the 08 AT sport has the same flanges as the 10-13 AT sedans non sport. My concern was the dimension and fitment of the coupe differential to a sedan.
