I have been having big problems with a limited slip front diff on a Suzuki Quad at work. The owner had let the bearings get so bad that the input shaft had come out of the diff and flailed round on the propshaft, smashing lumps out of the casting where the oil seal should go. As Suzuki parts are eye wateringly expensive we got new bearings & seals and a new half diff casting. The limited slip part isn’t shown in the official manual as a serviceable item so I left it alone. Of course when I tried the bike out, the diff was locked solid. So back to bits again, and I split the part usually housing the “spider.” This one contained neither spider nor gears. It is the weirdest diff I have seen. The half shafts fit into the strange face cams shown in the photo. One has a thrust and a Belville washer behind it, and a set of individual teeth slide up and down in splines cut into the crown wheel carrier, they mostly fell out when I split it and the whole thing was full of black gritty slime. After cleaning I tried re-assembling as shown in the photo, left tooth, right tooth, left tooth, etc, which looks logical. Diff just locked solid again. When I originally took it apart it didn’t seem to be like that, so tried two lefts two rights, two lefts, etc. This looks totally wrong but it does now work, what’s more when you turn one wheel forwards by hand, the other wheel revolves the opposite way like in a normal diff. How does that work? Anyone seen this style LSD before?
