Join the club(I'm not LS though )

 

never left a one legged mark on the L.

something isn't right in the rear end, unless ford changed something

 

what could be wrong?

 

1 wheel wonder lightnings!? couldnt be.

 

Clutches are bad in the differental. You could try changing the fluid but donot use synthetic, use the regular posi gear oil and add the friction modifier. The synthetic makes it worse. OH, and quick doing power brake burnouts, its just wears them out sooner. GET A LINE LOCK KIT FROM OUTRAGIOUS PERFORMANCE. No I don't work for them, I just like their kit.

 

i have a question, why would adding a line lock be better than holding the brakes and doing a burnout>? you make it sound liek its easyer on the posi if you have a line lock hows that?

 

Less load on the differential since you are not trying to break free from the grip of the brakes.

 

My Lightning has done the one wheel peel before at the track and when hard acceleration around a tight corner

 

the trucks 2 months old.....i shouldnt have to change any fluid

 

Id try to get the dealer to warranty repair it. BUT how are you gonna tell them you found out it didnt work. If you tell them doing a burnout that wont go over reall well

 

i'm sure that would work well........hahahah....i was doing a breakstand and.....but anyways what could be wrong?? i'm def bringing it in to see them. this thing is like driving a one wheeled truck

 

There is nothing wrong with your diff, or your fluid... Limited-slip diffs aren't supposed to always spin both wheels... They will most of the time...usually..but that doesn't mean that anything is wrong if it doesn't... If one wheel starts to spin and the other has considerably more traction, it will only spin the one wheel....
You see it all the time at the track with guys running slicks, if they don't get both tires good and wet..it will just spin one tire...usually someone will tell you and then you stop, back-up and wet them again then it will spin both...it's normal!

 

fomocofan is right on the money.

It's called "limited slip" for a reason.

From now on make sure both tires are on even types of surfaces and slowly start to spin them. That will help out.

WOT

 

fomoco is full of BS.
Limited slip will not stop both wheels from spinning unless one has GREAT traction and the other is all wet. It takes that drastic of a difference for that statement to have any valus. This will never happen on the track unless your clutches are failing, or you missed the water box on one side all together in which case a drag racing class is in order.
The line lock locks the front brakes and lets you release the brakes freeing up the rear wheels, power braking burnout must overcome the disc brakes. You are stopping and trying to spin all at the same time. Hard on the rear disc, and clutches. 57000 miles and never spun only one wheel, street or track. But have seen a few that did, and found burnt clutches from to much power brake burnouts.
