Fishtailing tacoma in the snow

I'm sure they do, but that doesn't mean your interpretation of what is said is anywhere close to correct. 4wd didn't work any differently in Canada than it does on the rest of the planet.

 

Are we now internationally spreading bad information?

 

He doesn't understand what 4wd is, how it works, or what a differential is apparently. Or what a "loose surface" is. Or what awd is and what it's intended for, which is the exact opposite of what he's saying.

iow, awd is designed specifically to be used in full traction situations. It is beneficial in snow etc, but you may notice how many sports cars are in fact awd, and their complete lack of representation in snowy, icy, areas. In contrast you see a lot of 4wd trucks.

Going back to the original ?, The reason youre sliding the rear end is because you're in 2wd. Hubs unlocked =2wd, the tcase position is irrelevant in that set up. But having manual hubs gives you the option of 2wd low, which is handy.

 

No way - I have tested this one out.

My belief is that the braking system puts far less little braking effort toward the rear as would be ideal on ice. The 4wd system will share braking effort between front and rear axles in the same way that it shares engine power between front and rear.

Maybe I'll run the test again and take some pics or video sometime.

 

Just because you believe something doesn’t make it true. 4WD does not help you brake. It has nothing to do with the braking system.

 

You will stop sooner in 4hi than 2hi due to increased engine braking but it’s not a huge difference. More drag reduction on the engine in 4hi as opposed to 2hi.

 

Yeah I can see that. But the brakes are a completely different system than 4WD. Please correct me if I’m wrong but I don’t think the braking system knows if it’s in 4WD or not.

 

Amen brother, beliefs and facts ain't the same.

However, a 4wd system DOES influence brake forces. Consider the example of a fully locked up rig, a brake on only ONE wheel (of sufficient power) could lock up all four wheels.

If your center diff is locked, or you don't have one as is our case, you could actually disconnect the rear brakes and then slam on the brakes - your rear axles will have braking force transferred to it by the drivelines.

In 4wd, the front and rear axles are rotationally locked together. This applies to both engine power and braking power.

See where I'm comin' from?

 

lol

 

Everyone knit picking.

4WD helps you slow down better than 2WD in the snow. There you go. Didn't use the word "brake" to confuse yall.

If you don't know why then think harder, or it's most likely cus you never drove a manual and have no clue what engine resistance does.
Just like putting it in low going down a snowy hill, much safer than "braking".

That's all, think before u respond to this please.

 

No, but I'm curious what color the sky is on your planet.

 

I thought this was gonna be a controversial one.

Here, I googled this up for you guys:

Have you read the owners manual?

 

Perfect. Good find.

 

In addition, after driving 200 miles in the snow last week, I would buy an AWD or get dedicated snow tires if I lived in snow country.

 

This time of year - it's almost always black.

You follow the example of a fully locked rig, how a brake on any one wheel would stop all four wheels equally?

Having 4wd engaged (with a locked center diff or no center diff) will change your brake bias to 50/50 front/rear.

 

The lack of a center differential forces the front and rear wheels to turn at same speed. That’s not good at higher speeds if you make any sudden maneuver. You can lose control in no time.
You see 4 wd trucks in the ditch all the time because they drive way too fast in 4 wd. Awd has a center diff....it’s much more forgiving. I max at about 45 mph in 4 wd in any snow conditions.

 

I think snow tires is good advice with any drive train. Neither awd or 4 wd does much for braking and turning in snow. Snow tires always benefit both.

 

Generally, that’s exactly right. Of course, everything is variable. So, lower speeds in 4 wd in deeper snow which provide more traction then ice or hard pack are generally OK. But I agree, over 45 mph in 4 wd is begging for trouble especially with non winter tires.

 

Exactly where ?
