What is the top speed I should run my 4Runner in 4wd?
Also, I assume I should not run the 4wd on dry road surfaces?

I wouldn't go faster than 60mph. Your assumption is right.

Why are you racing or something?
No you should not use it on pavement.

if you are on any terrain where you can go fast in 4wd, you probably dont need it... just keep it 2wd until it gets rough and then kick in 4hi...

i usually dont go over 30 in 4hi...

i have been up to about 55-60 on icey freeways in 4hi no issues here.

You should be able to go as fast as you want in 4hi. It's switching on the fly when you have to watch your speed.

out in the dunes Ive ran 60mph in low range in my 91 a few times, it was fine.

also in my Tacoma when we go to bend to visit family, i run around 60mph in 4hi no problem.

Was that in 8th gear? Just ribbing ya. Never tried to go faster than 10-15 in 4lo.

4Hi is fine when there can be slippage and I would say freeway speed would be okay, but if you can go that fast, why use it? (ice snow dirt)
4Lo I've only used wheeling where slow slow is better and at the boat ramp.

when i lived in utah i was in 4hi most of the winter often cruising 65 on the freeway sometimes on dry pavement and although i wouldnt recomend dry pavement sometimes you have no choice. i never had any problems tho i did that for 2 winters

TOYOTA 1

true, in my experience you can drive on the pavement in 4wheel drive with now problems, as long as you don't turn sharp.

although i wouldn't recommend it either

damn in 5th gear in 4 low im topped at 35 mph im redlineing

TOYOTA 1

wierd, my spedo would say 60mph and i was on the revlimiter"6,250rpm" i also had 33x12.50x15 swampers on so i was prbably going a lil faster than that.

TOYOTA 1

[quote=87LVRunner;50968599]lol i wish i had an 8 spd lol..

in the dunes you pretty much have to use 4lo, sand puts allot of drag on the vehicle. i mean you can use 4hi but it sucks not enough power

What could get damaged by driving in 4hi on dry pavement? Isn't that why there is transfer cases and slip in the diffs? I'm new to 4x4 so I've been wondering how I can use it. Basically, I want to use it to drive 25 miles both ways to work and school in the winter on snowy icy highways in Minnesota. Will I be fine using it in the winter for highway driving on those not so nice days or should I only turn it on when I "really need it?"

True this, and if you dont have enough speed you cant get up the damn dunes...

In low, 5th, im redlining ( well, idk if i am [no tach] but the engine is screaming) at like 35, which according to gps is 40...

904_runner

On dry pavement, leave it in 2wd. Why risk grenadeing something?

on ice, snow. idk but i wouldn't want to be going that fast anyways.

STEvil

You'll get a bit of gear binding but not much more than you already get by having a transfer case and a rear end to start with. If you can go 60mph for an extended period (15min+?) you probably dont need to be using 4wd. Otherwise it wont hurt anything thats not already weak.

Jay351

I have been up to around 100km/h in 4wd. In the snow....

Bill54880

I'm still confused, just because I'm new to 4x4's. What is it hard on to drive on dry pavement for longer than 15min's in 4hi?

i know that you can go faster in 4hi, but ive never been in a situation where ive needed it... besides only time when im in 4wd, im offroad, and, like i said, if i can go faster than 30, then i dont need 4wd...
