How has everybody's experience been with the limited slip differential (Traction-Lok) been in current Mustangs? Is it very good? The LS diff on some of Ford's trucks have a bad reputation and I'm wondering if the same is true of Mustangs.

I'm assuming that 2005 will have a similar setup.

 

Explain bad reputation...

 

Sorry, this is beat to death in truck forums and I'm too familiar with it.

They don't necessarily break down, they just don't work properly. For example, put one rear wheel on a slick surface and another on dry pavement. In 80% of the Super Duty trucks out there, you will just spin the wheel on the slick surface. No power transfered to the wheel on dry pavement.

This has been circumvented by the other 20% of users by changing to a different type of synthetic gear oil, changing the brand of the LS friction modifier or going through parts replacement under warantee.

Basically, will the Mustang spin both rear tires in the situation above? I'm not looking for Detroit-locker-like performance, just something to get both rears moving (without traction control enabled).

 

My Trac-Lok works fine. I regularly demonstrate its ability to evenly distribute power to both wheels... . Fortunately the Mustang can display this in easy to understand visual form, and it doesn't need wet pavement on one side.

yeah man, i hear that about ford trucks limited slips. my 2000 ranger has an 8.8 rear end with 3.55 gears and a limited slip. it does the same thing you are saying. if i have one tire, especially the right rear in something with less friction than the other, that right rear will always spin. if its the other way around, both wheels spin no matter what. likewise, if i go around a turn and turn to the right on lets say wet pavement, then that right wheel just does a one wheel wonder and i can spin for miles. i think there is something internal that allows that right wheel to only spin because my buddy had a f150 and his did the exact same thing. if i rev it up and dump the clutch and cut the wheel to the left, i can do donuts all day long on dry pavement. but the minute i try to come out of it and turn my wheel to the right....once again the right wheel just spins. anyways enough of my ramblings. i hope the 05 rear end is bullet proof and i can do figure 8's in the parking lot. this thing better be so rock solid that i can have one wheel in the ditch and still get both wheels to spin, not that iwould do that. the 05 better be able to get at least 3rd gear rubber, and that rear end better hold up and lay posi's the whole way!!!

 

V-10 trucks don't either..... B)

Thanks for the info.

 

I wonder if it is a weight thing, Jeep's only had similar problems w/ the Comanche & some J10s(Pick-up Trucks)
