I am getting my order together for a 2014. Can anyone offer real world insight into the differences between the standard ESC and the Optional Anti-Slip Rear end? I know the ESC is computer based. Is the Anti-Slip rear a clutch setup?
I had a LSD in a previous truck that was worthless so am reluctant to spend the money if it isn't really necessary. (Even though it's only 300 bones)
Intended uses are sand (beaches), snowy roads, fire roads, no rock climbing of any kind.
As far as I know, all newer vehicles are required to have ESC, which applies braking to which ever wheel the computer senses is loosing traction. Great for on the road lose of traction, unless you like to drift your vehicle, but sucks when offroading. That's why you can disable the feature. An anti-slip differential is a mechanism in the gearing to apply torque to a wheel that has a lose of traction. That's how I understand it any ways.
Life, Liberty and the pursuit of anyone that threatens it!
A lot of threads already out there on this subject. Bottom line, IMO, don't get the LSD from Jeep, but do get one aftermarket. I'd go with a TrueTrac. The LSD is always there, always doing its job (proactive) where as ESC is reactive. ESC is nice to have to compliment the LSD. ESC is not going to kick in during slower movements when you want traction. A LSD is always working to provide traction.
Well, I ordered my 2013 with the factory LSD. I've only had it for a month, so I can't really comment on it's performance. However, I did have factory LSD in my previous 2001 F150, and even after 12 years, the LSD worked fine. I'm in the same boat as you (OP). My jeep is a daily driver plus family outings, then, in the fall it turns into my hunting vehicle. I do lots of Dirt roads, some muddy roads. No Rock climbing or what people around here call wheeling. I do live in Atlantic Canada so Snow and Ice covered roads are very common, and LSD helps enough that you do not need 4WD all the time. Only a few days of winter do I need 4WD. Except of course, when I get home from work and I have 40 inches of snow in my 150ft driveway. Since the Jeep is part time 4WD, it is best not to use 4WD if the roads are only wet, but many times there are Ice patches on street corners but the rest is bare pavement. That is when LSD shines for me.
I have the factory LSD (Eaton Trac Loc) in the rear axle and a Eaton Ture Trac in the front axle.
Front hooks up easier, I have to drag the ebrake a little if one rear tire strats spinning. Other than that the rear hooks up well and you can't tell it's there under normal driving conditions.
Basic difference is factory TracLoc LSD has friction plates that are pushed together by springs not unlike to your manual clutch plate. They do wear down and eventully need to be replaced with new friction discs. I've got 50K on mine and they're still good. The fricition modified diff fluid is bloody expensive. $30 a quart. Takes 3 qts every 2 years for the rear axle.
The True Trac is all gears. They're a helical cut that locks up both tires under load. Works like an open diff until a wheel slips then it locks them together like a locker.
Great setup for stock axles. Won't snap axle shafts and doesn't jerk the wheel in turns like a full case locker.
The factory track lock is typically referred to as a trash lock...the clutches burn up really easily and it really does not provide much performance gain. If you are already looking at lockers then I would just up to a base rubicon and save the 10k in upgrades down the line if you can.
