What exactly does switching to H4 do?

OP, just open your diffs, and take a welder and weld everything together. At'll fix it.

 

But if one wheel is spinning, and the other one isn't, then all the power is going to air AROUND the wheel that is spinning.

 

I sure hope he tells them to use some gear lube to avoid getting splinters in their peckers. OH, I wonder if he tells them that's what "wood peckers" are, not a bird?

 

I didn't see it mentioned but I think up to 07 or 08, the TRD models came with a clutch based rear limited slip diff. All the newer trucks use the rear brakes to simulate limited slip (so the rear diff is as open as can be).

 

So, if the rear right tire is the primary drive tire, and it is spinning freely, with the accelerator pedal to the floor, what is the left front steer tire doing?

 

2nd gens have auto lsd after something like 08-09 (not sure which year changed), which is simulated lsd through the brake system.

 

You mean the LSDs from 07 or 08 and up are simulated LSDs? I thought only the 3rd Gens had the simulated LSDs. Just trying to clarify

 

If my memory is any good then I believe so. The "older" 2nd gens actually have physical clutch packs in the rear diff. The "newer" 2nd gens have a traction mode called "AUTO LSD" that applies brake pressure to the rear wheels to gain traction.

 

If one wheel is jacked up and spinning and the other is stationary neither wheel is transferring any power anywhere, except for the amount of power it takes to stir the air up around the tire etc which i'm ignoring.

Lower that wheel and both wheels grip and get power. My both or neither is definitely correct in our context.

 

Found this from 2010. I thought they were all mechanical. Did they switch when they did the facelift in 2012?

 

No, they switched earlier because of traction control devices being introduced.

 

Don't think about energy "consumed" by a wheel, think about energy "transferred through" a wheel. The energy transferred for our purposes here is energy that goes to the ground, moving the truck forward. If one wheel is spinning and the other is stationary and the truck is holding still, no power is being transferred by either tire because the truck isn't moving.

We know this usually isn't the case, because there's friction and heat even when doing a burnout. If you stomp the gas and one wheel spins like crazy and the other doesn't, you're still getting equal power transfer through both wheels. It's not as much as it would be if you weren't spinning a tire, but it's still equal.

 

If there's a skeeter on your peter, whack it off

 

When you turn the 4 wheel drive knob, a negative pressure valve off the manifold opens and accutuates the auto hubs in the front driveline. Now you're in 4 wherl drive. Then all the differential action takes place and off you go.

 

The issue that is confusing you is this thread of insanity very early on started using "power" when it should have been using "torque". An open diff delivers equal *torque* to each wheel at all times. Not power.

So go back through all the ridiculousness and when someone says "equal power" change that to "equal torque" and it will be easier to see why everyone is talking past each other and misunderstanding.

Good thing i'm locked front and rear, this thread is a shit show

 

Ok ladies and gents chill your shit.

I have jack stands and jacks ready. I have a selectable in the rear and an Aussie up front. What am I proving?
