I have a 1999.5 F250. I believe it has a Dana 50 up front. Do you know if late 99 or 2000's came with LSD differential up front? I know my rear is an open differential. Thanks!

99% sure the front is an open diff unless previous owner (if there is one) put a locker in.

thanks guys. that was fast.

Is there any way to test to see if its an open differential? If I could do a 4wd burn out I could find out but I cant lol

Pretty much same as the back, jack the front up and lock the hubs in (Might want to put the x-fer case in 4x4 too to keep front driveshaft from spinning). Spin one of the wheels by hand. if the wheels spin opposite directions you have an open diff.
