Mk3 diff ratio swap?

[Hellblazzer]

Hello there!
I recently discovered (if the vin plate is correct), that my 2.5di mk3, 5 stud from 1986, has a 4.56 diff ratio.
So now I would like to know, Is the 4.11 compatible in that axle?

Regards

If you have the square axle that the diff comes out the front of then I believe the 4.1 crown wheel and pinion that I have in my garage can be built into your diff. Brand new, wanna buy it?

Without some modification, the reduction gear of the rear axle MK5 with a gear ratio of 4.1 can not be installed on the rear axle MK3 instead of the gearbox with a gear ratio of 4.11.
It will be necessary to change the "sunny" gears in the differential box.
