4X2 on the boat ramp
 
Hi, looking at a 2012 or 2013 Laredo. I've owned two in the past and both times got the limited slip differential for pulling my boat (about 3200 lbs) up slippery ramps. Now, limited slip in the traditional form of a clutch pack carrier is no longer offerred and they have electronic traction control instead.

My question is: How well does this work? I don't want to go 4X4 unless actually needed as most of the time, it's just back and forth to work.

As I've haven't pulled a boat yet and I have 4X4 I can't say for sure you would be fine...but I'm gonna hazard a guess that you wouldn't have any problems. The brake-traction control and the supporting software are fairly advanced and I have had no problems with traction with my QTII, which doesnt have the ELSD in the rear.

Thanks for that. I too feel it will probably work, but the dealer will not let me test it even with a high mileage used vehicle. They basically said I should just take a leap of faith and buy the new vehicle from them and no, they won't take it back if it doesn't work for me.

I'm hoping people here will have the difinitive answer for me.

Tough call, snot slick boat ramps are tough without a 4x4.

I'd hazard to say if you have a 20' boat or greater, or say double axle trailer with fully loaded weight of 4k lbs or greater, then a 4x4 is the only way to avoid being the star attraction on Americas Funniest Videos.

YMMV.

Let me clarify by saying I currently pull my Ski Nautique (about 3200 lbs on a single axle trailer) with my 2004 Mach 1 Mustang (limited slip differential) and have no trouble. I know if the Traction Control System works as well as a limited slip, I will have no issue, I just have no experience with the electronic versions of these things.

Re: 4X2 on the boat ramp
 
Don't know what happened to my original reply, maybe becuase I linked to a Flickr photo? Anyway, my trailer is single axle and total weight is about 3200lbs. I've never had an issue with a traditional limited slip vehicle (89 Limited, 97 Laredo, 2004 Mustang Mach 1), so if the electronic limited slip works at least as well as the clutch pack type, I should be fine. I simply have no experience with this new system...

First, it depends on the ramp. If the ramp isn't too steep you should be OK. I pulled a 3200 pound boat/trailer with a 76 Chevy Monte Carlo for years with no problem.

Years later at a different location I needed 4 wheel low, depending on the tide.

If you are familiar with the ramp(s), ask yourself is everybody there using a 4 w/d.

As far as I know, the only way to get the electronic limited slip is with the 5.7L and ORII package (QDII).

I'm not even sure QTI would cut the mustard on a slippery boat ramp. I would get at least something with QTII.

Re: 4X2 on the boat ramp
 
Yes, I'm familiar with the ramp. I'm a competative skier and tow my boat to the lake 4 times/week in the Summer and 2 times/week in the Winter. There are many different vehicles in use there. The ones that suffer when the ramp gets a bit slippery are the ones with no limited slip and everyone with front wheel drive.

I have limited slip in my rear wheel drive Mustang and do not have issues. People with open rear ends often need help getting out. I'm looking for someone who pulls a boat with their 4X2 to comment on how well the electronic limited slip system works in this type situation.

Traction Control System - is printed on the Laredo Standard Options list that all the dealers put on their internet ordering pages. I believe it's on all models of the Laredo, probably because they no longer offer the clutch pack style limited slip option. I'll see if I can confirm that though, thanks for posting!

If you go to this page: Jeep - Compare Vehicle and Model Specifications - Highlights

Change the radio button at the top left to 4X2, then scroll down the page to "Additional Key Features" and click on "Electronic Stability Control." You see this text (just under the words Traction Control):
----
The Electronic Stability Control combines ABS brakes, All-Speed Traction Control and a stability system to give you the all-season capability of front-wheel drive with the performance of rear-wheel drive. It determines when to apply the brakes to one or more wheels, and when to reduce engine torque in critical driving situations. Always drive carefully, consistent with conditions. Please always wear your seat belt.
----

This is standard on Laredo from 4X2 3.6 and up.

Re: 4X2 on the boat ramp
 
I don't think ABS based traction control is gonna be very useful on a boat ramp. As others have already stated this is very specific to the ramp. The Jeep has a fairly short wheel base for a tow vehicle. I tow/launch/recover a 2500lb 18' boat with my WK2, my usual ramp is a beach entry and depending on the water level it's not uncommon for the rear wheels to go into the water. I do have a 4x4 w/ QTII, but I've never had to shift out of auto to get traction on my ramp. YMMV but i think it depends more on ramp conditions and how much rear traction you can get.
