i got two questions i have a 2002 f 150 fx4 with the 4.6 litre ok i kno the rear axle has an open differential due to the axle code is 19 but do the front axles have open diffs or are they lockers or limited slip? and how hard is it to install a detriot locker in the rear axle? any help is much appeciated thank you

 

Front is open. I know a few pre '97s were special ordered with front limited slip, but all were with rear LS first and designated with a three digit axle code.

Locker ain't too hard to put in if you want to do the effort. You need to find out if you have the 8.8 or 9.5 rear.

If your truck has a 4.6 in it it's a 8.8 rear.
If you have the 5.4 it's a 9.75 rear.
The front diff in both should be 8.8
