On the downside, front axles have U-joints and they generally don’t like the stress of a locker. Add in the lack of a rear locker and the front axle ends up doing lots of hard work. This can result in U-joint or axleshaft failure. Also, on descents the front axle wants to go straight, which can be a problem trying to go down a slope at an angle. If you have to back up all of a sudden, you are in danger of snapping a front axle because all of the weight of the vehicle is now on one U-joint. Add in any kind of a bind, and bam! This is also a good time to start watching your axleshaft U-joints spinning caps, stretched axle ears, and so forth. Lockers are not easy on parts!
