I have a 2000 Capri rear end on the Ciortina MKII estate -
but it's a 4:56 ratio,& the fuel milage (13 mpg) isn't very good.
I have a Cortina 3:90 unit.Can I swap them out.& keep the
same assembly?

Doug

Are you shure about the 4.56 : 1 ratio ?
Which type of Capri rearaxle is it ? Does it have a bolted cover at the back of the diff or can you take out the diff complete at the front ?

Doug,

Depending on what year Capri the rear end is from (and if it's from a 2.0l), it's a 3.44. The V6 Capris had 3.22. Early 1600 Capris had a 3.89. If the rear end is indeed that high, then it could be from something else. Did you look to see if there is a tag with the ratio on the rear end bolts?

The 4.56 ratio made me think also that it might be something else . Altough there are many more ratio's available for this axle i would not think anything higher as 4.1 would end up in a normal way in USA .
We realy need more info to answer the question .

Pete,

I went out & jack up the estate today,but the results didn't make
any sense.I thought that the driveshaft would turn 4 to 4-1/2 turns of the tire.
Is there a formula for that?

Put in neutral and jack up one rear wheel. Turn the wheel 2 full turns and count the number of turns the driveshaft makes. That is your ratio.

My Cortina has a 3.9:1. Thus two full rotations of the wheel will give almost 4 rotations of the driveshaft. A bit beyond 4 turns; 4:11 a bit more; 4.44 and so on.
It is difficult to accurately determine the ratio by doing it this way. You may have to remove the back plate of the Atlas R/E and count the gear teeth.
