My truck is fitted with LSD's as standard.

How do you know if they are workin' ?

In MUD only one wheel spins

Help, Kerr

 

You can try testing an LSD by applying moderate brake pressure when you have a slipping wheel to see if it will xfer power to the wheel with the most traction. That's how a LSD should work.

Hope this helps.

It's going to depend upon which type of limited slip you have. If it's one of the clutch type "lockers", then that is a bad symptom. If it is a viscous coupling or a Torsen type, then what you are seeing is expected behavior. Torsen stands for "Torque Sensing" and if one wheel completely loses traction, then the other can't be made to spin. That is why you more commonly see selectable lockers, spools and the clutch type limited slip in off road vehicles.

From the "How stuff works" website;
A quick primer on differentials is located at; http://www.howstuffworks.com/differential.htm

At best, a differential can supply equal torque to both sides, that is a locker. At worst, all the torque goes to the wheel with the least traction, that is an open diff. All limited slip systems are somewhere in between.

-edited to remove an incorrect statement- Thanks for keeping me honest HBoss!

 

As per Rob, it depends on the type of LSD you have. Do you know what type of LSD you have, by chance?

As far as I know (and as per howstuffworks.com) you can have greater than equal torque to each side with Torsen diffs and the way they bind. That's one of the reasons that Torsen differentials are considered superior.

 

Crap! You are entirely correct. I had convinced myself that that the bias was the other way, with the traction wheel getting 1/5 of the torque the slipping wheel was getting.

Doh!

I will edit that post so I don't leave the incorrect information in the archives.

 

lol. No prob Rob. I know you'd do the same for me. Even if you do root for the Seahawks.

 

I am telling you Man, take all your money, your truck title and your mortgage and put it on the Seachickens to take the Superbowl next year!

Then retire in the lap of luxury to that ocean front property in Arizona you bought and enjoy your beautiful view of the Brooklyn Bridge.

That will give you lots of time to install this Pringle's can in your engine for a 300 horsepower gain and 60 miles to the gallon.

You'll thank me for this tip, someday...

 

Pringle's can...300 hp you say...sounds like a steal...I'll take two.

 

I am trying to find out what type of LSD it is.

It doesn't even mention an LSD in the owners books.

But there is a sticker on the diff "Use LSD oil only"

I'll keep you posted

Thanks for all the help

I tested LSD a few times back in college. It seemed to work pretty good.

LOOK AT ALL THE PRETTY COLORS...

 

hahahhahaha I thought the same thing when I first saw the post...

Weren't those the days... If I NEVER see my walls breath or my carpet grow again, it will be too soon...
