Winter Driving in 4WD High

Go try it.

Only difference is that it'll be a bitch to steer.

No jumping no nothing. Only time you get that is if you lock the rear diff otherwise the Torsen based raptors are all open diffs.

I see you joined in June, I wonder how 6 months makes you an expert with your truck

Hahahahahah, i've actually only had the truck for about 4 months. But that's inconsequential because I know how a 4x4 system operates and how an AWD system operates.

Apparently not because you are still incorrect in regards to the Torsen diff in the raptor.

Not all 4x4 systems are the same

Even with front and rear diffs open the transfer case is locked. You will get windup between front and rear drive shafts. Front wheels do not spin the same amount as rear.

How do two wheels of exact size with matching diff fears not spin at the same amount?

They are never exact, and turning front will not follow the exact track as rear, check your tracks.

The fact that it's some fancy locker up front is a moot point. It's the tcase being locked which causes the binding.

Thank you.

I have to pee my **** is big says my wife and I ate old cheese have a bad tast in my mouth. Just drive straight and you don't have to worry.

Exactly - that is why you need that 'slip angle' aka slippery road surface to help prevent damage.

Also when turning, at any degree, the inside wheels, of any turn will rotate less than the outside wheels. The outside wheels have a longer distance (or wider radius) to travel than the inner wheels. That is why when say, the rear diff is locked on pavement, and tight turns are made, the wheels will skid, skip, etc... Same deal with 4hi/lo.

In a straight line, there's no problem, all wheels are rotating at the same speed.

I like 4 hi , use it ALOT here in MT. I just drove 325 miles on mixed snow, snow drifts, ice , wet , dry and slush. Pretty much had it all. Now one reason I like 4 hi on the highway is from the extreme cross winds we get here in the Eastern half of MT. The wind always seems to be 90 degrees to the road, and constantly slowing down and speeding up for corners , critters, and traffic, 4hi helps to keep the back end from breaking loose on the slippery stuff when trying to accelerate moderately with the xwinds.

Anyway, I never run 4 hi on dry paved roads, ( not that going to 4 hi going straight is going to explode the case, but if it's snow, ice, or mixed dry and snow , or dirt then if I need it I will. I don't take slow really tight corners in 4wd unless the surface will let my tires slip ., I use 4hi in town, driving around, and if I need to I just stay off the throttle and go to 2 wd, let if shift, then gently get back on the throttle, same for going into 4wd, off throttle, shift, ensure its engaged and back on the throttle, I never shift into or out of 4wd under a driveline load if I can help it. Which I almost always can.
