Yeah, I saw that write-up a while back, but I'm looking for a better solution. I tried this on my son's old Pede "non-BL" diff casing (was gonna throw it away anyway). Shaving away at the outdrive sleeve to fit the O-ring just reduced the length of the sleeve and caused outdrive wobble.
I'm just gonna live with the crazy diff unloading until there is a real solution.
Yeah, I saw that, but I've never been much of a fan of ball diffs. So, I'll just wait until a real diff comes out (if ever).
And I already got the FLM CVDs and they seem to be holding up well so far. They do use set screws to hold the cross pin in place, but also use a metal spring clip to help in case the pin gets loose.
I don't like ball diffs either. But this one seems easy to adjust and it's probably lighter than an oil filled gear diff. Does look like the gear is plastic though.
