To go faster! Haha. No my diffs were in perfect condition.

I went from 3.23 to 3.46 ratio. They were pulled from a wrecked automatic xi with only 40k miles.

To do the front, remove both axles, drop the front subframe (with motor supported of course), and that puppy slides right out after you disconnect the driveshaft.
