Electronic Locking vs Limited Slip Differentials

What is the main difference in these two in Ford pickups. I guess electronic you have to activate manually and limited slip is always available? Is one preferable than the other?

It has become a moot point for the 2015 truck, they seem to have eliminated the option for a mechanical limited-slip diff, offering only the e-locker and the open diffs. I think for the '14s the LSD only came as a fleet option or with the HD Payload package. I had to hunt for a while to find my used '07 with LSD, it amazes me that so many people buy one-wheel-drive trucks!

Your guess is correct, you have to use a control to engage the e-locker, and it automatically disengages when you reach some low speed (25 mph-ish) in most conditions and if you leave it on it'll re-engage when you slow down. It's recommended for off-road use only, where the limited-slip was always active.

EPA figures just released on 2015 2.7L Eco F150 2WD

19/26

4WD

18/23

That engine will pull any AS. The added payload should greatly help too.

Ford F150 Eco-Boost.

I have an '09 with the CPO warranty. It runs great. Last year it would not start just after a gas up. It was an emission part failure. It cost $200 at the dealer. I found the part for under $100 but since they had it I had them do it along with a flush and replace of tranny fluid and reprogram for $600 they did it all including emission part. That is my only expense aside from oil changes. The tranny fluid is outrageous alone so it was not too bad. The thing takes several quarts including converter.

I doubt any dealers will order 2wd around here.

There seems to be a lot of 2014 F150s still on the lots in my area. I may wait until this time next year to see the 2015s. I'm hoping with the weight reduction and the standardized 3.55 rear end there will be plenty of 4x4 SuperCrew with 3.55 and decent payload without having to resort to trying to find a rare HD Payload packaged truck. I've gone through the 2015 Ford Build to Order and the MSRP doesn't seem to be much different than a 2014 XLT with similar features.

The electronic-locking differential has a switch you turn. It will lock the rear axles together (under 20mph) on 2WD or 4WD F-150s. creating positive traction (both rear wheels turn at the same speed) without having to have spin first.

A limited slip differential requires slippage BEFOREHAND, during normal driving only one rear wheel will do the pulling but under a load there are clutches that lock up and cause both rear wheels to do the pulling. When one wheel starts spinning it will lock a diff clutch and then begin pulling with both wheels.

This as opposed to A non limited slip rear axle means that only one wheel will be pulling at any given time and there will never be positive traction.

I have regular limited slip but would like the control of ELSD. IMO, no truck should ever have open differential due to the nature of the beast. Electronic is best really because there are other things that come into play like cornering and rear end noise, etc. just my 2 cents.

Not sure I would go down to 2.7L EB...I am mostly happy with the 3.5L EB pulling the 25' AS. I think an 8 speed would give the 3.5L EB much better MPG, I'm guessing with the weight reduction....still hearing rumors that (8 spd) may be coming out....anyone else know for sure?

They are working on a multi-gear I heard up to 10 speeds. The EPA figures are a 2.7 with 3:31 rear rated to tow 7600 lbs.

I was wrong about pulling any AS but probably up to 25'.

Yeah the dealer here is loaded with 2014 models with tons of incentives.

How does the 8200# GVWR F150 EB ride empty? Just curious about how it compares in comfort to an F150 without the HD payload package. Thanks.

I would think it would ride harsher. HD Payload has different springs, HD shocks and LT tires on 17" rims that can be inflated to 80psi. There is a 2013 EB Lariet preowned not far from me but I found out it has a gooseneck hitch in the bed. Truck as 19k so probably hauled horses or livestock around with it. 19k in one year of ownership. They traded so I guess they went diesel. Truck may have had heavy use hauling. Not sure I want to bother looking at it. I test drove a 7700 GVWR 157" 2014 Supercrew and it rode nice. Right now I'm going to wait a year to see how the 2015s pan out. 2015 has big changes and is worth waiting. Maybe this time next year there will be a ton of 2015 closeouts.

The Off Road/HD package is a rougher ride all around in 4X4, F150 EB, from our experience. That's why we did not get it. We love our 2012 Platinum 4X4 EB, SuperCab, short bed ride...pulling or not pulling; it is a great vehicle...reminds me of our Cadillac! I encourage you to drive both at a dealer to feel the difference.

What is the usable load shown on the yellow sticker of your F150?

That is a lot. I checked out a 2014 SuperCrew with 7700 GVWR and it was 1765lbs. There is a preowned 2013 available with the 8200 GVWR so I figured it would be about 2300lbs payload. Is yours a regular cab model?
