Diffs?

[fireonice02]

I am wondering if any Liberty's come with a locking diff. If they do what 4wd system is it. I am looking at purchasing another Liberty and am considering a 2006 Renegade any suggestions?

No KJ ever came with a OEM locker,they did however have the option of the trac-loc LSD.It's a clutch type LSD and is shot after 30,000 or so miles and requires a friction modifier added to the fluid to keep it from self destructing.The trac-loc(more like the trash-loc) was a option for all KJ's,look for a green tag wrapped around one of the rear diff tubes that says trac-loc on it,if it says trac-loc it's got it,if not it doesn't.

Better to just pony up and get good lockers/LSD's installed.I run the detriot True-Trac in the front and the ARB air locker in the rear,a very great set-up for offroad.

06 libertys has traction control so you dont really need lockers unless you do heavy rock crawling.

Ive seen a liberty with traction control and it went everywhere mine did with a locker with just as much ease.

Sweet, I guess that's why mine has gone places in 2WD with good tires that used to need 4WD on stocks.

Does your True-Trac bind or make noise when turning, or is that just an auto locker thing?

A TrueTrac is a limited slip, so it will never bind. Also, it's engagement is seamless... You will never notice it happening except (maybe) when you're in the rain. If you give the Jeep a lot of gas in semi-slippery conditions (i.e., not sand), you will feel a minimal amount of slip but then when the TT splits the power, you will feel a little bit of an extra push.

I want a TT.

I want a TT.

Blake, you mean for the front, since you have a locker in the rear??

Did you price the TT for the front D30a yet??

I wonder if anyone here has run a DTT front AND rear?? I wonder what it feels like/how it performs?? I have driven a locked jeep and that is different.

Ive been thinking about getting rid of that locker and replacing it with a TT.

TT for the rear is around $400 but the install would kill me. I cant do gear work.

Yea, I would like to put DTT's in both front and rear but 1) I don't know how......and 2) having trouble finding someone I TRUST to do it......but I am wondering what it will be like because I have never driven a jeep with the TT in both axles.

A TT is just a gear driven limited slip. You probably wouldnt even notice it in the rear unless you got on the gas in the rain or snow, etc.

You shouldnt notice it in the front unless you have it in 4wd. Ive never driven a jeep with a ls or locker in the front but I can imagine it makes the steering heavy.

Okay, so the DTT is a gear driven LSD... Cool! Is it a variable auto torque biasing LSD like the Quaife (not available for a D30), or does it simply lock in at a certain percentage of slip, like most clutch based LSDs?

It has like 4:1 torque bias.

You are right about the Traction control on the 06 and up Liberty. The second a wheel starts to spin it sends power to the other wheel to get both of them spinning. I've been able follow people places who have lockers and watched people whole didn't have traction control or lockers fall behind.

I grant you, Traction control will never take the place a full locking diff but it sure does give you a some kind of extra edge when you need it.

Traction control uses the ABS brake sytem to apply the brakes to the spinning wheel and/or reduce engine power.Traction control CAN NOT send power to another wheel,it just applies the brake on that one spinning wheel and/or reduce engine power.It will wear out your brakes prematuraly and overheat them on the trail where the slow speeds will not cool the brakes.Can you say major brake fade!

my bad. Thats how I thought the traction control worked along with the reduce of engine power and the breaking. Then if its not the TT, then what causes my diff to act like it does. I know I have an open diff in the rear. I know when the diff is transfering from one wheel to another both wheels can spin for a couple seconds but I've already had them both spinning for a lot longer.

The brakes just brake the wheel thats doesnt have traction which gives the other wheel that has traction power. Causes both to spin.

And Im pretty sure it can reduce engine power.

In a open diff the torque will always go to the path of least resistance(AKA the wheel with the least amount of traction),traction control will apply the brake on that wheel that is spinning faster then the other side(via the ABS sensors) which in turn sends the torque to the other wheel with traction(more at least then the other wheel).In certain situations the ESP is what will cut the engine power to maintain vehicle control,the ESP and traction control(along with the ABS system) all work together.

Like I said this set-up will wear your brakes faster and over heat them after awhile.I prefer the TT and ARB air locker,at least the air locker is controlable and the traction control/ESP is not.

I had a new Dodge Charger for a loaner ( a couple months ago in the snow) from the Dealer. This was the biggest pieces of sh*t I had ever driven.

It had the ESP too. I have a steep hill to my house, and when I started up the hill with this car it started to spin the rears of course. Now once it broke loose, the ESP kicked in and I lost momentum. This leads to giving it more gas, and then the ESP kicks in again, causing more braking and loss of momentum.
If the hill were any longer I would have eventually came to a stop from the ESP. I tried shutting it off but it didn't seem to help.

So is ESP the solution? Maybe in some cases, but it depends on your driving conditions. Flat level ground it probably does what it was intended for, but for me where I live it just wouldn't cut it.

My opinion of the new Charger = (blarg)
My opinion of Traction control = notcool.gif

Ok so here's another question. A locker or a lsd in the front...won't that wear out pretty fast? Or eat tires? Put strain on the CV's?

If you take a turn the wheel that's on the outside lane spins faster then the one on the inside lane. The KJ has no lockable hubs so cv's and diff + driveshaft spin all the time the car moves.

So if the lsd or locker kicks in every time when there's a difference in left/right wheel rpm's

eeeh....anyone?

From what Ive gathered, if the front diff doesnt have torque on it then what ever is in it wont lock. Read about that stuff on cherokee forums many years ago.

And it really helps to have my Jeep in fulltime with the rear locker. Its pretty much invisible in fulltime.
