This is a tough one.... I did my front diff more than 12 years ago! I know I added extra clutch plates. I used two diffs to make one.

If I remember right, I took one of the springs annealed it and flattened it down. The clutches are not hardened and it never caused a problem. That combined with the extra disks reduced the preload. It also limits how much the side gears move in and out under load. The might be why I have never had a snap ring pop out.

I'm pretty sure I posted the details when I did the swap, I will also look for some pictures.

I'm about to have some down time for a week or so where the heaviest thing I will lift is a mouse. I will look when I get a chance.
