That is correct. On the Runner, you can run with the full TRACS/VSC system in 4 Low or lock up the center and have a conventional 4WD system.
#8 of 2487 question

on 4Runners. Can you use the 4 wheel drive in hi mode when driving on snowy highways? I know you're not suppose to on Dry roads. How much benefit do you get from the locking diffy when off-roading? Don't see many 4Runners with this option. Looking at possibly getting a used 4Runner.

I thought Toyota got rid of the locking rear diffy on the 2001's? I thought I also read somewhere that this option can't be had with an automatic transmission?

My first question for you is, what model year is your Runner? If you have a 2001, there is a center differential lock, and that places it into a conventional part time 4WD mode. This should not be used on dry pavement. With the 2001, it is safe to use 4WD high (unlocked center differential) on dry pavement.
If you are talking about an older one, they had a conventional part time system. Read back to the section here that discusses the Tundra and Tacoma systems. That should answer your questions.

To summarize, do you mean to say the the HL with 4wd and VSC is the least likely to get stuck in moderate snow conditions? Also, is the limited slip dif a clutch or plate type? What is the likelyhood of its needing service?
Thanks for all your informative posts.

if I can only use the 4x4 off road, then it really isn't worth getting if it can't be used on pavement in snowy or bad road conditions during winter.

it appears that I can use the 4x4 during adverse weather condtions on pavement, as long as it's not dry. Just how "bad" is the key.

On the HL, the least likely version is the 4WD with the VSC. The limited slip differential in the CENTER is a viscous coupling, while the optional rear LSD is a clutch type. The down side to clutch types is that they wear out. When they do, you may not even know it. They will just behave like a normal open type.
#16 of 2487 Highlander , mobile-1 syn gear oil?
Jun 08, 2001 (6:02 am)
On the awd highlander there is a sticker on the center differential that states 85w-90w , would it be ok to use mobile 1 syn 75w-90w gear oil? you mention that when the front wheels spin faster than the rear, the heavy liquid firms up. so should a 75-140 be better?
