X2. part time 4wd is not recommended for street use and 4lo is not recommended for speeds above 35mph. but there are no time limits. check your toyota owner's manual.NorCalTRD said:no, i drive in 4 low as long as i need to. you just dont go fast.
I usually run 4HI in the rain on pavement... How about that?4xClover said:No you can drive in 4 Low as long as necessar - NorCalTRD said, just don't go fast. Of course, this is only the case when you are OFF pavement. ON pavement you should not use 4 Hi or 4 Low.
It has nothing to do with the differentials. It's a matter of transfer case design. Most AWD cars and SUVs utilize single-speed transfer cases for weight savings and because a low-range is not needed by most consumers.stu said:Since this question will probably answered pretty quickly, let me ask another one.
Would there be any benefit to a "low" setting on a strictly AWD vehicle (like a RAV 4 for example)? Also, I know the difference between 4wd and AWD, but I don't really understand what happens that changes the gears to the "Low" gear. Would it even be possible to have AWD "low" without a locking differential?

The transfer case on an AWD or full-time 4WD uses some sort of device that allows speed differences from front axle to rear axle. A standard two-speed transfer case locks the front and rear driveshafts together.
I would categorize having locking differentials as being far different from a low-range, regardless of vehicle.stu said:Any input on this? I'm just curious.
stu said:I've already read that whole page, and like I said, understand the differences between the two. Let me rephrase my question.
In the opinion of members here, would there ever be a benefit to having an AWD "low" setting in a vehicle. I'm thinking that there would NOT be much benefit because the way AWD works is the same as having three open differentials (kind of) and if you were in a situation where you needed a "low" gear, you'd probably be better off with a locking center in the first place.
I have very limited wheeling experience, so I am having a difficult time imagining a situation where you'd be in "low" and it would be beneficial to have the front tires turning at a different rate than the rear tires.
Any input on this? I'm just curious. Since I don't have another truck yet, it gives me plenty of time to ponder useless situations like this.
