I am hoping to get a 4x4 Screw soon and I have a question about limited slip. If I get the 4x4 do I need limited slip and why or why not. Any info would be appreciated.

Thanks,

Joe

I have the LSD in my screw, I didn't have it in my Y2K 150 longbed, I'll never be without it in a pickup again. If you don't mind spinning your tires when you really want to get going...don't bother with it...if on the other hand you want to go when you depress the pedal and the ground is moist....get it....it's something you'll hardly notice when your test driving unless its wet out...but you'll regret not getting it the first time you pull out onto a highway and your tires start spinning and your not going anywhere and the car behind you is coming up fast...of course, this is just my $0.02.......

Just remember that you are not always in 4wheel drive. I agree wholeheartedly with Screwloose.

 

I had a '00 F-150 2WD SuperCab with a 3.31 gear and open rear end. My '01 F-150 2WD SuperCab has the limited slip with 3.55 gear. The LS is *A LOT* better on any kind of wet surface than an open rear end. I don't intend to ever own another vehicle without it. I don't go offroad so the only time I start thinking of 4WD is when I'm in a foot of snow. I use mine for hauling a 5,000 pound boat up launching ramps which sometimes are slimy and always wet.
I wonder what I would be thinking if I got stuck in a 4wd watching only one front wheel spinning. But then I've never owned 4wd. Want, yes, need no.
My '01 has the 5.4/superchip/WMS intake and BFG P275/60R17 tires. I do not have any problem with wheelspin on wet sufaces, even hauling the boat.
I would like to see it as standard equipment, but this is already about a dimes worth of $.02.

 

Also, if you go off-roading and you get a front and rear wheel in the air (sounds crazy, but it happens)... you are stuck, no drive....

 

Get it. You'll regret it if you don't.

 

Thanks everyone for the info. I thought limited was the way to go but was having second thoughts. I would have posted sooner but my DSL line was down today. Thanks again everyone!!!!!!

 

When I ordered my Screw, I didn't get LS. I've never driven a vehicle with it and didn't feel I needed it. I haven't had any problems with getting around, and I drive regularly across IL, WI, and MI.

Then again, I also enjoy spinning around in the slush a bit too If I ever needed some weight back there, I'd just put a couple rows of chopped wood in the box.

Those of you who have it, most certainly know it's worth, This is just coming from a good ol' boy who loves playin' in the snow.

Gotta love this truck.

PS - whoever the guy in the other Screw I talked to while waiting at the stop light, (waiting to get onto 12 Rand Rd.) Nice chatting with ya, great looking truck, GOTTA LOVE IT.

 

Gotta have that limited slip. Actually I think that Ford should make it standard on there F-series trucks.

I can't see any reason that anyone would not want limited slip, other than additional cost. But if Ford only made LS rears for there trucks then maybe it would make them cheaper VS having the option.

 

I think the LS is worthless.

while i am of the mindframe that 4x4 or 1 front and 1 rear tire will get me out of any jam, it has. In other words, i've never been in a position when i have thought i needed a LS diff. Lockers might be nice, but LS does little.

Just for more proof, 2 weeks ago, a couple buddies and I were out wheeling at this place that had a ramp. My short box reg cab has the open 3.55 and a buddy has the exact same truck - but an 01, and has the 3.55 LS. We did the ramp test, same size tires, same wheelbase, same anything that would make a difference, but he had the LS diff. We climbed the exact same height. That is to say when his front tire started to climb off the ground, *one* rear tire started to spin.

And while i have no proof except my own experience, i think that on pavement where 90% of our mileage occurs, an LS can count for more fuel useage.

Ummm, w/o a l/s, locker or a spool as soon as 1 tire looses traction that entire drive axel is just worthless. Get just a little crossed up and you will be dead in the dirt. Unless you have some sort of traction aiding diff's you will have NO wheel drive.

big grinn his front tire started to climb off the ground, *one* rear tire started to spin.)

Spend some time with someone who knows how to work his truck, watch them tap the brake to lock the l/s and drive off the top of the ramp. While the factory l/s isn't the greatest, it does work ok. Also, having ANYTHING other than an open diff in the back is going to go faster around turns because you'll limit the wheel spin of the inside tire. Off road there is NO comparison, traction will win every time.

(And while i have no proof except my own experience, i think that on pavement where 90% of our mileage occurs, an LS can count for more fuel useage.)

ok, you may win here. There is a very slight difference in mpg, less than could be calculated using the measurements of our trucks. 1/10 of a mile on the odometer is just not accurate enough. Throw on a Rallye computer and it would work, but then the tire spin on your open diffs would contaminate the findings.javascript:smilie('')

FLAME SUIT ON!

 

I own a f-150 supercab xlt sport 2x4 ....and I don't like the LS I would rather have a locking dif. the LS is crap in snow and in wet conditions all the power goes to one wheel...if it's wet out all I do is spin my tires at the lights..

 

With a 4x2 I would get a L/S.
With a 4x4 I would be less inclined too.

As a 18 year owner of a F150 4x2 with a L/S, I can recall quite a few snow & ice storms when the L/S was needed. At least both rear wheels were driving snow to get the truck rolling from a dead stop. I was always to lazy to add any weight to the bed. Again this was all on-street activity. If any regular off-road excursions are planned I would of course have a 4x4 with l/s. Just an opinion.

I would be curious to see any data reguarding the mileage cost of a L/S.

I have ordered L/S with my new screw.

 

Now Im really confused.

I just ordered a 02 4x4 Screw with the 3.55 LS. Sounds like some of the replies incinuate that this is a bad decision?

 

All I'm saying is that i have have had no need for it. it's chocolate and vanilla as far as i'm concerned, different flavours for different tastes.
