Limited slip in reverse??
Does limited slip work when your F250 is in reverse? We have a 2003 PSD and I had a difficult time backing out of a yard on muddy grass. It was just a slight grade and the right rear wheel just spun and spun. I thought the other wheel should take over when this happens. I guess with the 7.3L there is just too much weight up front.

The short answer to the question is yes, LSD works in reverse. It's a wet clutch pack inside the rear axle differential, and is bi-directional.
Good advice on tapping the brakes to get better LSD function.

there has been a lot of talk in the past regarding the amount and quality of the lubricant that ford used in the diffs. you might want to check the levels and/or replace the oil with a more suitable type.
most ppl that have done one or both of the above have reported MUCH better operation of the stock LSD. do a search and see the full discussions.
or... if you want to spend a few bucks... get a detroit locker and 'forgetaboutit' !

I can't seem to find anything in a search about this. If anyone runs across info please post.

sorry... it was a while ago 
i would guess in this forum or the offroad or the suspension forums.
you might also look in the oil forum as that is where it SHOULD be.
might want to look over at ford-deisel.com too... they prob have posts on this.

OK, Here's a few of the past threads that addressed these issues..

Looks like the answer is:
Make sure your clutch packs are in good shape, (less then 50K they're probably OK)
Make sure you have the right oil w/ the proper additives, (Check your manual or talk to a reliable dealer)
Use your parking brake if you need the LS to kick in when not moving,(they're designed to function when both wheels are spinning)
Kick out the dollars for a Detroit Locker
Good luck and happy spinning!!!

This is a misnomer.
What you really need is PRELOAD on the clutches. Load makes the diff spider gears want to seperate from each other, applying more pressure to the clutches.
To get that preload, you have to hit the brakes (or parking brake) and apply some power. It will usually get you more lock-up from the stock LS as long as the clutches aren't glazed.

Thanks Art,
Sounds reasonable, I never did understand quite how it works, just that it does.
