I have a 2000 SD PSD 6spd 4X4 3L73:1 That the sticker shows it having a LOCKING rear. If I take in the mud, or on a twisty ditch crossing only one rear tire will spin. I have been told by a FORD Tech that some of the rear ends came mislabeled and did not have a locker in them. Any one of you have the same problem or hear the same thing?

Thanks in advance,Terry.
P.S. Is thare a place that some one can enter the VIN number of there truck and get a copy of the factory assembly sticker.

 

I wouldn't necessarily believe the FORD tech. When I bought my previous truck it came without a limited slip differential. Since I told the dealer I wouldn't buy the truck without L.S. He said they could swap the rear axle with a truck which had it. I always wondered if someone ended up with the other truck thinking they had a limited slip rear because thats what the sticker said.

 

The new LS rears suck to put it lightly. The clutch packs are very loose and do not grab as they are supposed to. My 94 F250 had a real LS rear that would spin the inside tire on the dirt when turning. When I would spin the tires, BOTH would turn.

I was under the impression that the only rear differential with a locker was the 4.30 rear end. That is what I have with my tow package. This info came from a reliable dealer I deal with through my work. Check it out.

 

I have a 2001 excursion limited, 4X4, 3.73 limited slip rear. While driving in the snow last year I noticed that when I started from a red light I would spin 1 rear wheel if I stepped on the throttle too hard. took the truck to the dealer and did some research on my own and found out the following. The new limited slip rears suck, in plain english, the clutch packs are set to a really loose spec. if you throttle the V-10 too hard it just breaks them loose, if you continue to spin your differential the clutches will wear out in short order and you will end up with the $380.00 regular differential option. The way ford intends for the axle to work is, when you start to spin you are suppose to stop and apply just enough power to turn the wheels and not break them loose, this way both rear wheels will drive the truck. I was told that if you apply the brake a little while doing this it will help. I also found that those that have the 5.4L don't notice this problem, I guess ford should tighten the clutch pack for the V-10. I haven't been able to find a ford fix so when this bothers me enough I have to go to the after market and purchase a differential that works. Good luck, let me end with this.
FIND A GOOD DEALER, FORD WILL BE OF NOOOOO HELP TO YOU ONCE YOU TAKE DELIVERY. IF YOUR DEALER WON'T GO THE EXTRA MILE, YOU'RE ALL ALONE.
