im no expert on this topic, being that this is my first vehicle with it, but from the bit that i know i understand that with it then my rear wheels should always spin at the same speed right? well here is my dilema. about a couple of days ago i was leaving my house got in the truck and put it in drive and pushed the gas. only my rear paseenger side was spinning due to it being on some ice that had formed in the curb gutter. look over and see that my side rear tire is just sitting there. so i am basically stuck on the side of the road. my truck is lifeted 6" and has 35s on it, and it just got stuck in the side of the gutter from a patch of ice.! im sure it looked pretty funny should both of my wheels spin so it would pull me out using driver side wheel? i took it to a empty parking lot and tried to power brake to see if both wheels would break loose and they both did, and then again i did the old stomp around a turn and it definaltey seemed like the inside tire always spun faster then the outside. any input would be apprecitaed. should i get this checked out? please teach me.

 

Factory LSD uses a series of clutch discs that will lose their efficiency over time. Depending on how many miles are on your truck and how well the rear end was maintained, it will determine how much slip is going to happen. Because its "limited" slip, its still going to allow the other wheel to slip a lot...but it will still transfer a small portion of power to that wheel to at least get you moving. A factory LSD rear end in good working condition might transfer 25-35 percent of available power to your non slipping tire...but thats really in a perfect world. If you find your stuck, put the truck in 2nd and SLOWLY apply power...just stomping on it is going to overpower the LSD and like you discovered, you will just spin the one, no traction tire. Doing a burn out on pavement where you have good traction to both tires will get you much closer to a 50\50 power distribution to both tires...again, as you discovered.

If you want both wheels to spin at the same speed, all the time, get a locker....but it will eat rear tires much faster and your street driving manners will drop off sharply unless you get a selectable locker(ARB, etc).

 

awesome answer, thanks a lot. my truck has 71k miles on it, every thing is in good condition but you can tell that the previous owner did have some fun with it sometimes (paint chips from rocks behind wheels on fenders.)

 

On the money. I swamped out my factory non-posi to an Auburn locker, and street driving has changed w/ respects to going around corners on pavement... I tend not to goose it through the turn since the inner tire is trying to pass the outer every time. But its AWESOME IN THE MUDDDDD

 

What Auburn locker do you have? I thought they made only the limited slip with cone clutches and the Ected electric locker

 

i put a ford racing locker in mine and that solved all of my problems. totally worth the money

 

I have had good luck with the Detroit Truetrack in previous vehicles ive'd owned. It is a limited slip that uses worm gears instead of clutches and will not wair out. For my 06 I am contemplating going full Detroit Locker on it because I only drive it in the winter time and I want to be able to drive it anywhere I please.

 

I purchased the Auburn Auto Cross Limited Slip from 4WP. It is a limited w/ cone clutches. It also is set up with a racing cross-pin system (helps in cornering, main reason for choosing this one). Granted on smooth concrete the squeal can become annoying, but I'd rather have a squeal every now and then in the city, and still be able to get out the country. Havent gotten stuck since I put it on (even had to pull out my uncles 350 4x4). MT Baja ATZ's prolly help alot too

 

I looked on line and didn't find that to research, would you mind providing a link?

 

You may want to do some research and possibly rethink that. An auto locker is not a great choice for winter driving. Ask anyone who has been on ice with one.
