Rep Power: 0 if he offroaded a lot he'd have bought a locking differential... at which point has to be activated by a switch (locking differentials use a electric, hydraulic or pneumatic mechanism that has to be activated by an outside switch to either vary pressure or send an electrical signal to activate it, unlike mechanical or commonplace lsd which are mechanical)
so yep, mr. durango if he was a serious offroader would have a locking differential and if he did have one, neglected to say so and as such, he more than likely is not a serious offroader and either he's lying about his story (which I think he is) or he's a complete moron (which I also believe).
So he's driving a stock durango and claims that he's a serious offroader... BS. They have a LSD which is swapped out for for a open differential or a locking differential (locking differential is the same as an open except for the fluid/electrical activation). So no LSD for a serious offroader... so he's a twit.

i dont get it, youve never seen a car with posi? one wheel immediately breaks loose then if you let off and get on it again sometimes posi will kick in and both wheels will have traction (maybe i didnt word this best of my ability but its true, not both wheels will have traction right away......many of my friends have posi and i have witnessed this)
as for the shifting.....its called kick down, in an auto tranny depending on throttle position and rate of acceleration the tranny will kick down 1 or 2 gears......i dunno if youve driven auto but i know youd feel it and realize it if you floored it in an auto. auto's dont start out in true first gear, ther are big differences between first that it starts out in and when you actually put it into first, its called select first when you manually select the gear and it goes through a different power flow in the tranny than first starting off the line.
and you can sense what wheels are spinning and when, its easy and in my jeep i could tell too, in fact in my civic in snow/rain if i spin them by accident i can tell which are spinning.
im not calling you out, we all know your very knowledgeable but you were a D!CK to this guy, even though he is a freakin idiot for racing a truck that supposedly is capable of mudding, and racing with a family in the car.

and you merely repeated exactly what I said, which was that an LSD is not something that turns off or on. it's always there, and is working the moment one wheel starts to slip. this guy, however, claimed that his "limited slip" didn't kick in right away, and made it sound like not until he got to a certain speed did it start to work. LSD's simply don't work that way.
i have a decent knowledge of LSD's, and in fact, have taken apart my own diff and tested the LSD on my S2000.

Rep Power: 400 i never thought about that. that is true that trucks often do have dissimilar parts to a car's auto tranny. good point.

Well..... there is a difference in LSD and posi. Posi traction means the rear tire are locked all the time. Yes, this is bad for street driven cars, hence it is pretty much just used in drag cars today. However, 30 years ago when my dad his muscle cars, lots of people had posi traction, and he siad you could feel the rear tires skip when you turned the car. LSD on the other hand is a LIMITED slip differential, meaning it has the ablity to slip a little before it locks. This is much better for todays car that are on the road, I have this in my truck. However if you have stickly a drag car, this is bad, because during your luanch you have a slight bit of wheel spin, which for the mortal person doesn't matter, but for the few out there that a .1 seconds is important, and they're car is ONLY a drag car, posi is good.
There is anouther kind of locking differential that off road drivers uses that is actually switch on and off. This allows you to drive the truck to the off road site with a posi style (always locked) differential, hit a switch, and have a locked rear end. A posi style (always locked) rear end is desirable in off roading becuase a little bit of slip can be just enough to get you stuck, I know, it sucks having to pull my truck out with a my tractor
Anyway, summerizing, you have 4 type of rear ends (or differentials since I am on a civic sight here, must remember the FWD):
1. open - common on most cars
2. LSD - for dailing driving, limited locking
3. Posi - drag racing, always locked
4. lockable - off roading, locked with activation switch
This guy I think has a LSD in his durango, to my knowledge no car/truck has ever came with a "lockable" type differential from the factory.
^ thanks for gettin that.
plus one thing, not all lsd's are the same, they can be all set to allow different amounts of slip.
oh yeah, the "im this dumb after reading this thread" chart was A+ material hahahaha

posi and LSD are the same thing. you're thinking of an open/locking differential.
and OPEN differential (with a few extra parts) can lock the rear wheels together. also called a locking differential.
(not all open differentials are locking differentials)
s2000man01 is correct. posi and LSD are the same thing. in the 1950's and 60's manufacturers began to name their limited slips. "positraction" was chevrolet's name for their unit just like ponitac was safe t trac, ford is equa lock and trac lok, AMC was twin grip, Mopar was sure grip and ferrari was E diff. all of these are limited slip units with different names. this is common confusion in the differential world but here take a look

okay.. yeah posi is a LSD, but my point was that there is a permentaly locked differential... summit sells them. I've also seen people weld the differential together to lock the tires to the same speed.
I thought open differential never really locked the tires together, ever.
you can have a locker with is usually eclectronic, pnuematic, or hydrolicly controlled from inside the cabin of the vehicle. the differental will have be open until the locker is engaged. what your thinking or is welding the spider gears together to give the same equal power to each wheel. a posi will still give more power to one wheel it just limits the slip of the wheel that is putting down less torque

Yeah, that's what I was saying... the ones that can be locked from inside a car/truck are generally used by off-roaders and no I didn't mean that was the same as welding the spider gears, I was saying those are two different types or ways to go about locking a differential, unless you can turn a weld on and off
