Damage? Highway in 4H

In 4wd tires need the opportunity to slip. The opportunity to slip on dry, hard paved surfaces is severely limited. AWD systems allow drivetrains to slip and avoid binding. This is not necessarily the case with 4wd systems.

You have to explain yourself better. Modern 4WD (in these tacomas) is identical to the 4WD of old. It's still the same identical front and rear driveshafts spinning at the same rate. Modern AWD is new, but we don't have that.

- As I said, I am very familiar with how these 4WD systems work. Driveline bind is absolutely a factor, but unless you are extremely overloaded the driveline is plenty strong to handle it. Go 4wheeling on slickrock and your tires will bark as the bind unloads when you turn. I've wheeled in Moab for more than a decade and I have never broken a driveline component. Thats far more stress then driving on a street or parking lot. Unless you use lots of throttle you wont have issues.

These vehicles are not delicate flowers

 

All I know is growing up on the farm driving late 50's to early 70's vehicles & equipment while experiencing the bind with snapping/cracking/lurching of various 4x4's is unlike any 4x4 or AWD system I have driven since, the late 1980's.

 

They were all gear driven transfer cases, which are uncommon now. But thats because chain drives are quieter. They are all "part time" 4wd systems, which dont allow any difference in rotation. AWD systems have a center diff which is different but our trucks dont have that.
