WHy do people say not to put a locker in an IFS??
Beats me I got A Lockright in the front and rear of my Tacoma and Love them. Yea I have broke a couple Cv's but thats cause I like to show off and both time I got on the skinny. If you drive with a little common sense you wont have too many problems.
As far as handling goes I dont know the front's there on the road with hubs unlocked. Since I live in the south I don't have to deal with snow so the only time I lock the hubs is on the trail. Now on the trail sometime it can be a bear to turn the wheel while stoped. But i've found out that if I just let the clutch off just a little to get the front wheels to turn the least little bit then I can turn the wheel.
