I have searched this topic and still have not found what I need, so here it goes. The handle on the 424 won't lock into place at all, I have taken it apart several times, cleaned and lubed it each time. After I clean it it works for a couple of pulls, and if i lock it in 2 wheel drive and let it set, and then come back and release it, it will not lock again. I have noticed on the brass part that the ball bearings are in, that there is a groove on each side of the holes that the bearings set in. It seems like the holes that the bearings are in have become larger of the bearings have shrinked, because they stick in the holes pretty good. Any ideas would be helpful, and is there any where to get replacement parts, warn only has the cable replacement on their website. I am just thinking about buying a slightly larger bearing and see if that helps. Sorry for the long post, but this problem is really ticking me off. Thanks in advance.
