I don't have a problem with L/S diff's, my problem is I want to get rid of that POS E-lock and get and LSD so it will work on the go without stopping and putting it in low range just so I can use the E-lock. Where did you come up with that? Question is does that Ford have one? Give me the code off the rear axle and I can tell you. Keep your mind off the sheep and on the drving and this type thing won't happen to you! LOL!Bama talk all the sh!t you want about a LS diff, But this one saved my *** today! If the truck didn't have it I would have been stuck. I was going down the road not paying attention and hit a deep *** mud hole.
