I ran a lockright in the front 30 of my TJ. 95% of the the time on the road you will not know its there. Make a sharp slow speed turn and you will hear some clicking.. this is normal.. However if you drive snow covered roads, I would recommend saving the extra money and get a selectable unit such as ARB. Reason being a full time locker in the front,(any of them) will make steering a bit crazy as it will tend to pull left and right as it one side gets traction then the other. ON the other end I also ran a rear detroit locker in my cj and in snow it was great, no issues..on the road when shifting it would sometimes cause the jeep to jump a bit.
