Project Fiesta ST, Improving the Drivetrain with Mountune USA and SPEC Clutch


The ring gear bolts were removed.
Once the bolts were out the ring gear was tapped off the differential with a soft mallet.
You can see the stock diff is a conventional two pinion differential.  The mountune/Quaiffe diff is considerably different looking and in operation as well!
We pressed our new long awaited bearings onto the mountune diff.
Since the ring gear is such a tight fit onto the body of the differential, we used a heat gun to expand it before installing it on the new diff.
With heating, the ring gear slid right in place.
