What would cause the locking hub to engage while driving? I finally got a few minutes of free time and have been messing with the blazer again for the first time in forever and took it down the street for a test run. I get this clicking noise coming from the front end. I get out and check everything. The left front hub is halfed locked. Weird. So I unlock it all the way and go for round two. SAME THING! After about 1/4 mile the damn thing goes into half locked position! ALWAYS something!! These are the Warn...I forget the number off hand, but the ones for the 35spline outters on a D60. Thanks.
