i have a 90 toyota 4 runner and i just want to know how fast can you drive in 4wd? What is the safest speed that i can drive in 4wd without anything breaking?

40-45? maybe

I've driven 60-70mph many times for extended periods on many different toys over the years with no problems. I'm sure some will dissagree.

If you need 4wd you shouldnt really need to go very fast.


I think somwhere in my truck it sayes not to go faster than like 50 in 4wd....

i think 60 is fine, i have done it many times in mine.

i have a 98 4Runner, V6 4x4 and the manual says not to engage 4wd over 25 mph and not to use over 55 mph. i don't know if the earlier years are different

Drive only as fast as conditions warrent. I have seen many 4WD in ditches because the owners thought that 4WD means they could drive 70 in snow.

Yep. I've gone 70. It's fine. It's a Toyota afterall. Your just not suposed to shift into 4wd that fast.

I've had 'er up to 70 quite a few times. No big deal. I don't shift it in and out above 55.

you can shift out of it at any speed and 4WH you can shift into it at any speed under 50 but im not sure about 4WL

dexter

dont shift into it under 50. i have hit 100 before once in wyoming when i knew the road was dry and ice free for a few miles inbetween snow drifts

I've driven at 65 or 70....keep in mind that just because you can doesn't mean you should. Can the 4wd handle it, yes, of course...do the conditions warrent it? that is your discretion....

Keep in mind that in many of these toys, the only difference between 2 and 4wd is the front driveline is disengaged from the engine, but all of the axles and driveline are still spinning, only difference is in one you are coasting, and the other has power.

tends to push slightly in 4wd with both hubs locked in with lockers in the front and rear, if i had the money i would have went with an arb, but i have the poorman's way, i jus only lock one hub in and its pretty controlable, had it maybe to 45, i just don't like hittin that greazy ice slush, you just kinda hydro across it, but i usually just keep it in 2wd, cause i still go jus bout newhere i'd want

155 mph . . . . but that's in the STI (technically "all wheel drive"). I drove 60+ for quite a ways coming back from Tahoe in snow driving my truck. I've done 70 in the desert on graded dirt.

[Edit] Sorry, I had to ride the bike down to the pizza place to get dinner and didn't get to finish my post. The truck has always impressed me with its capability. I agree though, don't ever drive faster than the conditions, including your skill and your surroundings, allow for safety. 155 is best left to the track.

You can go as fast as your truck will take you. But what purpose would that serve? I have gone over 70 in 4wd a few times; it did not explode or anything.

well i was stuck one time and the speedo hit 110

I was driving 70mph in my Land Cruiser and my friend (who's also an excellent Toyota mechanic) pushed my center diff lock button.. putting me in 4WD. I started freaking out, but was told to chill and the truck can handle it, just drive straight. Was on dry pavement, we were trying to isolate a little "whirr" from my T-Case. The tranny is the same as on the Runner, T-Case may be a little different, as different as a 96 Toyota is from a 96 Toyota... I guess what I'm saying is don't worry about it, if you happen to shift into 4WD at 51 and the manual says 50, heck your tires are probably bigger than stock so your speedo is off anyway.

Swissdrums

hmmm...i tend to only use 4wd when needed, which is only when i cant do something in 2wd...i think the trucks cv's and transfer case components should be baby'd. If your driving 50+ in 4wd, you dont need to be in 4wd. Just my 2 cents

mike_d

if you need 4wd, you don't need to be going fast. go as fast as you can go safely in the conditions. everyone has 4 wheel brakes - you won't be stopping any better with 4wd.

dexter

the reasoning i use for using 4wd over 70 is changing lanes through the slush and for messy sections of roads. i feel much safer having all 4 wheels getting power than just two for some reason seems safer to me
