I recently installed a Alloy USA axle lock kit for manually locking in my front axles 2000XJ but 1991 front axle. Followed all the directions and everything went smooth except this thing is a bear to actuate. The cable and actuator are installed correctly I just cannot believe the operation should be this stiff. Has anyone else had or experienced using one of these and was the operation of the cable really stiff? It does operate but not without some muscle. Thanks
