4WD issue? 6MT

Imagine if it had more torque. The binding isn't going to change, but with a bit more torque something else will give.

 

Only tires, the drivetrain is one of the strongest points of the truck. I have binded vehicles with 190 ft-lbs to 610 ft-lbs. The tires simply do not have the traction/resistance needed to cause a mechanical failure. The tires will squeal and slip before gearing or anything else ever will.

 

I think OP needs to clarify if this ^^^ statement is an exaggeration. I have felt 4WD binding, in a manual truck, on dry pavement, and never once was it “like I slammed on the brakes”.

 

I think he just means the truck stopped. Sounds like binding to me

 

OP has TSS of which I have no experience with. As far as I know his truck could have just gone Christine

 

This is often forgotten when these conversations come up I feel like. While binding is not optimal, the tires only have so much grip. They should slip well before anything in the drivetrain gives even with excellent traction but it's still bad practice none the less.

 

I was going really slow speed, maybe 2-3 mph, and it jerked to a stop. So yea, slamming your brakes feeling. If I had been expecting it to do that, I'd have put more into the throttle. Just never felt a vehicle bind as badly as this did, which I'm wrapping up to low torque at low rpm. Guess next time in 4wd in a parking lot, I'll just keep it wound up around 3500, shouldn't have issues aside pedestrians dodging me. *sorry sir, don't want it to stall out on me, so watch your ass*

 

There is no question here. The guys answered your question correctly with binding. You must never use 4WD if you haven't experienced this in 20 years. I last experienced it... Saturday lol.

 

Haha, I've experienced it, just not this dramatic. This godamned truck is a drama queen I guess.

 

Binding occurs because, unlike an AWD vehicle, there is no center differential. In 4WD, all 4 wheels are turning at the same speed. That's fine in a straight line or when your on a low traction surface. But the moment you turn, you change the path of every wheel. The vehicle is a single unit, and as such, is always moving at the same speed as a unit. But each wheel now wants to move at a different speed based on it's new path. Inside wheels will turn slower and outside wheels will turn faster, as they have further to travel within the same time frame. You don't really notice this because the front and rear differentials "differentiate", allowing the wheels to turn at different speeds .

However, since there is no center differential to "differentiate" between the front and rear axles, they are now trying to turn together at the same speed as the vehicle turns. This is not possible. The front and rear will fight each other...each trying to turn at whatever speed is required. The tires will grip, lose grip, grip, lose grip. That's the binding your hearing and feeling.

Binding = bad. Don't do it .
