I see there is a lot of hate for the j30 haha. I have it, and it's awesome cause i'm not peg legging around town anymore, but it has locked sometimes when I haven't wanted it to. Example - light drizzle, I'm waiting to turn left at a red light. 2 turn lanes, I'm in the outside lane. I was about 3 cars back from the intersection, so there were cars in front of me and behind me. About halfway through the turn, the back steps out...I didn't change gears, change throttle, or anything. Back slides out, I countersteer and basically drift around the corner. Scared the sh** out of me. Had I been in the inside lane, I'm sure I would have tapped the car outside of me.
What am I going to do about unpredictable locking? Shim the diff. Shimming it puts pressure on the locking plates making the diff lock more easily.
