haulingit Posted February 2, 2021 Share Posted February 2, 2021 (edited) Getting ready to order a 2021 Lincoln Navigator L, Reserve with 4x4. An option I am including is the Heavy Duty Trailer Tow Package. While looking in the December 2020 Order Guide it mentions an option described as "Electronic Traction Assist (Electronic Limited Slip – eLSD) Rear Axle (62E) now available as a standalone option on Navigator Reserve (200A/201A/208A) and standard on Navigator Black Label (800A)" I don't see this on the Lincoln Navigator vehicle Build webpage, no matter the configuration selections I make. Is it available for 4x4 Navigators? I ask because I have an impression it is a feature for 4x2 vehicles. If yes, how much is that option? thank you Edited February 2, 2021 by haulingit Quote Link to comment Share on other sites More sharing options...
HofstraJet Posted February 2, 2021 Share Posted February 2, 2021 1465 invoice / 1665 MSRP on my invoice for a 21. I have a 4x2 Reserve so I can't answer about the 4x4. Check the order guide on this site. Quote Link to comment Share on other sites More sharing options...
haulingit Posted February 3, 2021 Author Share Posted February 3, 2021 I found an article that said it was include in the 2020 Heavy Duty Trailer Tow Package. I brought up the 2020 Lincoln Navigator Reserve build webpage, and the description for the Heavy Duty Trailer Tow Package includes the wording "Available on Reserve Series (4x2 and 4x4)". 1 Quote Link to comment Share on other sites More sharing options...
theoldwizard1 Posted February 3, 2021 Share Posted February 3, 2021 (edited) IIRC, eLSD simply applies the brake to the tire that is spinning. The open differential "does its thing" and send power to the opposite tire. Some Ford products offer electronic locking rear axle. A better option, IMHO.

haulingit Posted February 3, 2021 Author Share Posted February 3, 2021 there is a video here about it https://owner.lincoln.com/support/how-tos/safety/driver-assist-technology/trailers-towing-loading/electronic-traction-assist.html the eLSD concerns the rear axle, and video says it adjusts torque to the non-slipping wheel, it doesn't say anything about braking, but maybe thats part of it Quote Link to comment Share on other sites More sharing options...

It brakes the slipping wheel. Quote Link to comment Share on other sites More sharing options...

Brake and Engine Actuate Traction Control is a standard feature and that's been available as Traction Control since they went to 4 channel ABS a couple of decades ago. It also says this in the description: Rear Axle – Electronic Traction Assist (Electronic Limited Slip Differential – eLSD) So I think it's safe to say this is the E-Locker.

That is not what a LSD does and I feel certain an eLSD doesn't either. A LSD send torque to the non-slipping wheel. In the eLSD context, it isn't purely electronic. I don't know whether Ford uses this unit but if you read this page, there is hydraulic actuation involved to send torque to the non-slipping wheel. https://www.eaton.com/us/en-us/catalog/differentials/intellitrac-differential.html 1 Quote Link to comment Share on other sites More sharing options...

JustMeInUSA Posted April 9, 2021 Share Posted April 9, 2021 My 2018 Lincoln Navigator L without eLSD has no obvious problems in the snow. I purposely tried to get it stuck many times and it would not get stuck. Towing doesnt seem like a problem at all. If you are getting eLSD for either snow or towing...well...it doesnt seem like it needs it in my experience. Maybe it might be for very extreme conditions. The winter storms here have not been Canada or Maine like. Maybe for certain extreme towing it would be helpful. However, I didnt feel like I needed it.

Traction control can help a lot by braking the spinning wheel sending torque to the other wheel, but it can't send torque to both rear wheels equally at the same time. I don't think it's really needed in most cases. I have it on my F150 but only used it once and even then not sure I needed it. But 30 years ago I got stuck in the back yard when one of my Ranger rear wheels hit mud and ever since then I vowed never to purchase a truck without it.
