Quasi Lockers with ESP

[Newtybar]

I remember awhile back reading that those without lockers could "ghetto rig" the Jeep to behave similarly and lock up the rears using ESP...

something about pumping the handbrake?

[dpoelstra]

The rear limited slip with traction control is very good compared to limited slip alone or the old "posi" traction.

You really won't need to do anything with the brake, since the traction control automatically applies the brake to the spinning wheel, helping the lmited slip limit the slip. I have coupled the stock limited slip rear with the traction control with a locker up front and go everywhere I point it.

A little example.

Good articulation, keeping all four wheels on the ground helps as well.

dp, I think the OP is talking about the BLD that're on the JKs. If so, you don't need to pump the handbrake. I think 2 clicks of it is all you need and the BLD will activate. I'm sure I'll be corrected if I'm wrong.

[dpoelstra]

BLD???

What is that?

Maybe a stupid question, but I have done some of the toughest black diamond trails in southern California and have not had to use by hand brake at all, and have been able to go where others have either not been able to, or not had the nerve to go.

Please expand on this BLD.

Thanks,

BLD - Brake Lock Differential. Applies the brake to the spinning wheel.

On whole the total LSD system of the JK is better than any Jeep has yet to produce. The older LSD's, used in CJ's, YJ's and TJ's, were all but useless. My JK, in 2wd, has better traction than our TJ, or the neighbors new FJ, in 4wd.

[jeeperjkj]

Yeah, BLD and LSD are not the same. BLD is standard on JK's, whereas LSD is an option and is basically a step up from BLD. And of course true lockers are the best.

For a good description of BLD: http://blog.chryslerllc.com/blog.do?p=entry&id=270

I don't have LSD or lockers. I have experienced BLD in action and can confirm that it does in fact work- just not as well as LSD or lockers. The thing to remember if you have only BLD is that when a wheel loses traction, you need to stay on the gas (the common reaction is to let off the gas). You need to allow the wheel to spin for a few seconds for the computer to kick in and do its thing. Of course the problem then is that it takes twice as much torque to get power to the wheel with traction. This means in all likelihood that you will now need to push the gas a little harder. Now the downside to this is that once you have gotten beyond the obstacle, you'll experience a sudden lurch as all that extra power lets lose. So you need to be ready for that- I have an automatic, so I just cover the brake with my left foot in preparation for that jump.

It works, but it takes practice.

Sounds like it might be a good first step for a Rubi before locking the rear, too, huh...

I have nothing to contribute to this thread. I just thought it was funny how you made a contraction out of "that" and "are." That're. :rotflmao2:

[muddpuppy01]

every time I have had bds kick in it has all was stop me in my tracks mainly do to both rear tires spinning and locking them down to match the front

I just hit the esp button and floor it again

Sumthn' funny 'bout that? :what?:

[dpoelstra]

Actually that is kinda funny:rotflmao2:

Anyway, my comments about LSD with traction control is the BLD that you talk about, just different names. I have the stock rear with "BLD" and a lunchbox loker in teh front and go everywhere. Most of the guys I wheel with are amazed that I am not completely locked front and rear.

It is a great system, and when it wears out, or just doesn't work well anymore I will switch to a selectable locker, but for now it works great, and I do nothing to activate it. I just drive as if I am locked.

:thumbsup:

BLD is standard on all JKs, and it is not in the axle, it is purely brake activated, and works front and back. A LSD is still an option for the JK, as is a rear locker (full lockers with Rubicon).

That is probably the traction control kicking in. Once the esp is off, the the bld can do its work.

And here I thought LSD was only popular back in the 70's.

put it in low and leave it :)

no more problems :)

[dpoelstra]

your right...two seperate systems that work together really well. I happen to have LSD and traction control (BLD), which is great for a "quasi-locker". I don't think that either one with out the other would be all that great.

[RedneckJeep]

My understanding of the BLD is that it has absolutely nothing at all to do with the parking brake. Where that came from, I have no idea. In fact, I would bet that if you tried to engage the parking brake, it would probably totally confuse the BLD and cause it to not operate properly.

[dpoelstra]

I have heard guys with Limited slip only using the parking brake to get the LS to engage. Don't know if it works....

[SpinningBull]

I have the LSD on my JK, and was unable to go on the swamp trail organized run - couldn't get past the safety check. Lockers required.

A lot of the organized runs I go on post clearly that you have to have at least one locker to go on the advanced runs. LSD not enough.

That being said, I haven't had any trouble on the runs I was on! I was able to climb a waterfall on "Winch Hill" on the bear creek run on stock tires! It was tough though.

Anyway, I went and added a front locker and will be checking it our tomorrow. I let you know if I notice a major difference.

The boys you're with don't wanna be embarrassed by the capabilities of your Limited Slip. I put in a front locker to go with those "elite" drivers and have yet to use it with them. I'm quick to let'em know it too.

The whole thing with the parking brake is with the antique LSD's in the TJ's and such. You had to pump the brakes or hit the E-brake to get them to activate. Those who're still livin' in the past can't seem to accept that someone finally got somethin' right and the systems do really work without any help from us.

Any issues with MY contractions?:evil_laughterpurple
