2005 XC90 2.5t Auto AWD - Rear differential ratio value???

Post by LuthierIan »

Hoping someone has a simple (or understandable) answer to finding the value of my final rear differential ratio for my 2005 2.5t automatic, petrol, XC90 please. I’ve done a few hours googling and the best figure I’ve got for 2.5t final drive ratio is 2.862/ 2.56 (ie two figures!)

(The 2.56 is used for the T6 for sure.)

Now the final drive can only be one of these values so which am I looking for in a 2.5t replacement unit? Someone out there will have an understandable chart I’m sure. Thanks in advance
