Hello guys, I wonder if any of you could help. I need to replace the rear differential for my vellfire. It’s a 2010 3.5L AWD (GGH25W). I have been trying to find a replacement from either ebay or Japan like amayama/beforward etc but I have some questions. The part number I usually see is 41110-58060. Most of the part they have are coming off from the 2.4L model/alphard or a different model eg Toyota voxy. Given some of them shared the same part number and have the same final gear ratio, am I right that i could just do a direct swap? Has anyone tried it? Are there any issue the bolt position etc? Not a mechanic but trying to source the part for my mechanic to replace. Based southwest.
