regular rear end VS locking or limited slip

I am looking at the 2011 F150s...i had wanted certain things including certain colors. the dealer was looking over area inventory and said nothing was out there...in the pale adobe that i wanted...but i said. yes there is ...here is a windwo sticker i downloaded from another dealer on the ford site...

he looked at it and said well i want to sell you a real truck...and that truck isnt a real truck..

he was referring to the REGULAR rear end. he said i wouldnt want that...id want to make sure i have at least the limited slip rear if i wanted a real truck.


soooooo

whats the big deal with regular rear end....non limited slip?? if i get in a slippery situation, while i just spin the left rear and right front...and thats it???

he says with the limited slip the power would transfer to the other side of the truck and I might get out easier.


thanks

bob

you can add LS for not too much money if it bugs you, if the rest of the truck fits your needs and you can't find one any where else get it.

They do help when you are in slippery situations. It would cost you about a grand to put a Limited Slip in after the fact. Maybe more depending on what brand you buy.

It is all personal preference, but I won't have a pickup without a locker or Limited Slip. It makes a 4wd pickup closer to what a fwd should be. At least you will have 3 wheels spinning in snow instead of one on the back and one in the front. Makes a huge difference. That is my personal experience.

a grand? that's outrageous for a basic limited slip. that's getting into selectable locker territory.

w/ my fx4, i can't even notice it being open diff'd. both tires spin when i punch it in a straight line, feels the same driving as every other truck i've had.

We need to know the power train you're looking at?

well i have been only looking at the 5.0 V8... I hunt like crazy all winter....towing a big duck boat. I am in situations that range from farm fields, and rutty farm roads to steep snow and ice cover boat launches in january!!! many ramps arent plowed...plus sometimes the ramp surface runs into mud and or sand...but the truck will also be a daily driver all winter long.

my boat-motor-trailer combo is probably around 2300 lbs. and once in a while i tow a 6x12 flatbed loaded with mulch or dirt....

I almost bought a truck , but i read a thread here about what to pay...in relationship to dealer invoice..and the 2 dealers close to me are having NOTHING to do with "below dealer invoice" and i kinda want to stand my ground if I believe the info on the other thread...but maybe i am uop against an area of dealers who have stood their ground...

the one I was negotiating for has a 3.55 limited slip rear in 5.0 and the large tires 275-65-18.

Bob, were they willing to do invoice? invoice is a good deal, still better than x-plan.

for me to get below invoice, i literally called 30+ dealers which none had what i want and almost decided to hold off on buying a truck. if you want the below invoice price you are going to have to put ALOT of time into it. i dedicated over a week to getting the deal i wanted.

no...but to basically lay the deal on me and my new truck on the table9 getting away from rear ends for a moment)

37,300 mspr...we didnt talk price at all the guy went right into writing it up..trade in(2K + $1000 ford kick in for trade) price $35,200, +$600 for DMV documents-paperwork,+2K plus for taxes +a few small things...then he tells what my loan is for 60 months 0%=$589 something!!!! i say whoa...you flew right by negotiating..and any down payment in cash i have!!!

tells you he wants it all financed!

after I balked..about invoice the manager got involved and blew some steam and talked about "ill show you my real cost" and he went online and looked it up and printed a page..pulls it off the printer...then... FOLDS the bottom 1/5th and goes over to the copier and makes a copy...and gived me the copy that doesnt show me what was on the folded section!! then tells me he is "TRASPARENT"....

I said... you dont have to be ashamed of making money, but you do about lying

the DEALER INVOICE was 34,400...the paper said...

they never moved and i didnt offer anything.. I just left.

later I emailed the salemans and I offered $33,500


thats were we left the negotiation..so i think he is still at 35,200 which is a lousy 2,400 off MSRP!!!!!!!! we emailed each other about "below invoicing pricing" ..they wont do it...and we havent communicated in 2 days.

but i was going with the notion from a previous thread, that i should get the truck somewhere below dealer invoice

I see internet sales on xlts at 29,999 for trucks that MSRP at 36,800

they have to get down that low some how other than incentives and cash backs...

soooo the regular rear end is a dog or no??

I grew up and started driving in "The Hill City" of Lynchburg and my parents never had LS rears in our cars, Daddy didn't like them because of accelerated tire wear in city driving and some drawbacks in slick stuff like a LS rear will put you sideways faster. He relied more on snow tires and chains if needed. We had good snows back when I was starting out driving and I even drove some mail trucks and school buses in bad snow and ice back in the early-mid '70s and never put a chain on either.

I did have one set of large 15" studded snow tires I invested in once and kept on spare wheels when I had to be able to get to the bus garage or Post Office. I never bought myself any tire chains.

In 31 plus years as a trooper driving police cars in all kinds of weather, snow / ice / floods / muddy trails on assignment in SW Va, etc .... and seeing as we NEVER had limited slip and I used chains some in the very early '80s, in the 1993 blizzard, and in Dec 2009 storm (that's right, many winters I never took the chains out of the box) ... not such a big deal. (Up to about mid '80s, we even used snow tires in winter and in later '80s on up, all "M&S Rated All Season" tires ... state always provided tire chains as needed.)

It's more often how you drive that counts.

Even with an open rear end, power is devided evenly between the two wheels, traction however is limited to that traction available by the wheel with least traction. If that right rear wheel is spinning but still pushing forwards with 50 pounds of force, the left is also applying the same 50 pounds pf push even though it's not spinning .... so let up on te throttle, be gentle, and ease it down and be patient.

LS rears when opperating correctly, apply full power to both wheels by trying to spin both rear tires at same speed, thus the wheel with good traction has the power to push the vehicle forwards.

On a icy roadway, limited slip can just as easily put you sideways and the rear into a guard rail. What I learned many many years ago was to drive like there was an egg under the throttle and before anti lock brakes, I used the rear brakes only often by using the hand / parking brake. I have been known to tie the parking brake release open with a wire from a coathanger for these times.

You are looking at a 4X4 PU, far more important than a LS rear end is your technique and the tires you choose. Not all off road tires are good for cold snow and ice conditions. You want rubber that stays soft in colder temps and the sipes help with ice. Many off road tires are deep lugged but made with harder rubber to resist rock damage and the rubber is hard as a rock at low temps and those tires often near useless.

A set of tire chains is good insurance and far cheaper and transferrable. Likewise, if you ever got a second set of wheels and decided to have a set (or just a pair) of same sized snow / ice only tires, just stud them.

If you get a good deal on the truck you want and it has an open rear, you can ALWAYS add an aftermarket LS or locker (think Tru-Trak) if you find you NEED it later. I think having traction control will help quite a bit even with an open rear.
