I put in 4wd H lock. and turned the front tires but didnt notice the front tires jump. so there is something not locking in the front end?


Was the engine running? The system uses engine vacuum to move the front axle disconnect and engage the fwd. Sometimes weak vac won't do it, and you have to rev it and snap the throttle shut to get it loosened up and working...
