Whenever there's large puddles on the edge of the road, and I run them over, my car pulls to that side hard. For instance if I'm in the left lane, and there's standing water on the left edge, my car pulls left. Same for the right.

Is this because I have an open differential?

Would installing a LSD minimize this behavior?

Why does this happen in my 240, then? Lightweight?

Also would a LSD make this worse, then? Or is it irrelevent?

One way you can avoid this from happening is to just avoid driving over puddles or slowing down when there is a puddle. Puddles are caused when constant water source gets into the road that has a dip or a bowl shape.

Open differentials do no contribute to this behavior (one wheel isn't being moved by the driveshaft at all so it can't pull to the right) & LSD will not correct this.

I can't tell if you're trolling.....

Anyway, its simple, you just needed to think about it more. If one tire goes over a puddle like that at a fast speed, that tire has less traction than the other tires. Therefore, the car will pull towards that direction.

Nope, just stupid. I have done a fair amount of trolling though.

With an open diff, all the power would be sent to the one hydroplanning wheel, right?

Wheras with a lsd, the one wheel with traction would still see power.

So how wouldn't this affect this phenomenon either way?

I'm just trying to reason. I'm looking for both an answer and an explanation, please.

I'm a good driver, with the exception of those multiple counts of manslaughter. They were all from the same incident though. Damn kids lemonade stands.

Dude, you are hydroplaning. There is NOTHING you can do about it except avoid the puddle. Use your brain.

Can you actually explain why the differential won't affect the handling of the vehicle, in this case?

I'm trying to be intuitive, but I wasn't sure. That's why I'm asking here.

If you can't figure out why your car is pulling when you hit a puddle, you really should not be allowed to get behind the wheel. You are not be intuitive, you are being fu**ing stupid.

I don't think you're understanding what I'm asking. How does a differential [not] affect hydroplanning due to one wheel losing traction, and why?

You're starting to sound mad. You're not mad are you?

The differential controls the rear wheels. When you hit a puddle the force from the water jerks the front wheels, which are the only ones with the ability to turn. When your car pulls it's because of the front wheels, not the rear wheels, and therefore the dif has absolutely nothing to do with it. If you were asking why the back end of your car goes sliding out, THEN the dif could be a possibility.

Are you really bringing the "umad bro" into this? Grow up or leave this forum. We don't need immature jacka**es like you here.

how do you not understand? even if it was dirt not water, the loss of overall traction would pull the momentum of the car, regardless of the differential

stop overcomplicating this try to cover up your stupid question...

dont listen to these guys bro!!! its magnetism! your cars being pulled around by an outside force! alienssss!!!!

lol, nah really, LISTEN TO THESE GUYS BRO.
hydroplaning has zip to do with the rear diff. 0, nothing, nada.
if you want to know how a diff works and dont understand the way its been stated, go to howstuffworks.com or google images, there you will find pictures and even a video on the functions of a limited slip differential. its fun stuff.

have a kickass day amigo.

As far as I'm aware, these are all stupid questions. I'm just trying to understand, I have no shame when I want to learn something. I already searched for this question on Google and on here and couldn't find anything.

Thanks brah. Although I still might not be able to figure this out; I'd also need to read on car physics. I was just wondering if anyone knew, and also if they could explain why. The thing I'm having trouble with is picturing how the outer rear wheel getting power (with LSD) would affect the "pulling" of the front inner wheel as opposed to the outer rear wheel not getting power (open diff). Now that I think about it, wouldn't you be more inclined to spin out w/ an LSD? I know people say to be careful in the rain with one, but I'm assuming that has more to do with both wheels losing traction during turns.

Thanks again! EDIT: That's an open differential right? You said LSD so I'm not sure.

Okay, so, with an open differential, because the one wheel loses traction, it's free to spin faster (no load), and does? Meanwhile the other wheel loses power because it's been distributed to the other wheel? It's a passive process then; that's simpler than I though.

How do I get my wheels like the ones at 8:47? Nice offset.

Brilliant people say brilliant things man..... I still don't under stand why he doesnt understand hydroplaning...its retard simple.

Like really i knew the effects of hydro planing before i ever drove a car.



i'm showing my g/f that video she asked about what random car things are and do like daily.

I understand hydroplaning of the front two or rear two wheels. Just not when it's only one side. It's not obvious to me why the front wheels would even pull on one side instead of staying straight (I'm not turning the wheel, I keep it straight). It's not just my front wheels, my car's getting pulled nearly parallel to the road. I assumed for it to pull, both wheels on one side have to lose traction.

...Because you are hitting a puddle on THAT side of the car. If you hit a big puddle dead on with both wheels, it wouldn't pull the car to either side

Right... but I don't understand why. My lack of understanding is what prompted the diff questions, because I'm trying to fill in the blanks.

It's like understanding that if you throw something in the air, it'll fall back down, but now knowing about gravity.

See that stuff right there? I don't have it.

If it's so simple, please explain it. In basic terms; friction, momentum, forces, etc.

EDIT: My reasoning is that deep water creates a minor "speed bump" slowing the wheel and causing it to turn before losing traction because it is then spinning slower than the opposite wheel. Is that correct?

lol basic terms are not "friction, momentum, forces"
think abut it like this, when you are driving, and you hit a large puddle with the right front wheel, your steering wheel as well as car pull to the right (same goes for if it were the oposite side) what happens when the car pulls to that side is this, as the cars momentum is moving in a straight line on 2 tracks (the wheels, left and right side) one track suddenly encounters the puddle (water) this substance momentarily but somwhat drasticaly effects the free forward movement of the track (but only on one side) while the opposing track continues in the forward motion uninhibited by the water.
in a simple manner, wheel hit water, wheel suddenly slows down, other side does not slow down because other side has hit no water and continues causing the "turning" or "pulling" effect you experienced.
this effect is magnified greatly in the front of the car verses the rear because the front wheels can move side to side. when the weight of the car is pulled to the side which has been impeded, the tires in front will natural turn in that direction, if only a minor movement, it translates into a heavy feeling the "pulling"
it really isnt hard to understand, nor hard to figure out. damn man.
if you still have confusion after reading and watching all ive given you, you need to go somewhere else.
