I don't have a owner's manual for my 1989 4Runner, 22RE, automatic tran.

Does anyone know what's the maximum speed I can go in H4/L4 with the hubs locked? Winter is approaching so I'd like to find out.

It's stock and I am running 235/75R15 tires (don't know if this matters).

Thanks.

 

fast as you can

 

Serious? If you need 4x4 during the winter, you need to drive according to the conditions. just because you might be able to drive 55 (which is the fastest I would recommend in 4x4) doesn't mean you should.
4 low, no faster than redline.

Are your tires decent tread?

 

Ocdo has got it right.
Ist not a matter of how fast you CAN go, its a matter of how fast you SHOULD go. I was stupid in High School and would go 70-80 in 4wd with my '93 p/u on my way to school on the pure ice/snow roads here. Im not stupid anymore. I drive like a grandma and I'm only 20. But I have never been in an accident, never been in the ditch, but have spun out doing 50 driving to brake because a moose ran in front of me. Luckily there was a snowbank

4wd does not help you or make you stop faster. It just gets you going faster. And of course helps when its snowing so much you can only see 50 feet in front of you and theres about 8-10 inches of unplowed snow on the road

 

Read your owners manual.

Or, just drive yourself into a retaining wall

 

rig up some sort of backwards transmission and disconnect so what when you need to slow down or about to head on into a bank use the other tranny to go reverse and make the wheels push you way

 

rolf.

My 4wd sees 50 all the time going down the road...but on the interstate, I dont even like to have my hubs locked. Unless it is absolutely necessary. Get good snow tires that will make a huge difference. I run stock size Cooper Discoverys and they have never let me down. Dont run mud tires, they are horrible in anything less than 3-4 inches of snow.

 

About 60-70 mph tops, You can go fast enough.

 

My point was if you have to ASK how "fast" you can go in your truck, you either need to get an owners manual or stop trying to break the sound barrier in a Toyota.

 

Should have said that the first time then.

 

Apparently implied logic is not nearly logical enough for you.

So for all the halfwits and jackwagons who read this thread: If you need to know how fast your Toyota should go in 4WD, buy an owners manual. If you want to know how fast your Toyota CAN go in 4WD, press down on the accelerator.

Clear enough now?

 

Youve been on pirate to much. Whats with the hostility?

Dosent hurt to be nice.

 

If I have to put my truck into 4wd in the snow I never go past 25-30 MPH if I am lucky and always have it in 4lo. I hardly ever use 4HI for anything.

No reason to go faster than that in snow whatsoever. If you do, then you deserve whatever is coming to you when you roll off into a ditch. And when you do then don't expect your 4wd to get you out of it cus your probably gonna need a wrecker to take your truck to the scrap yard. Notice I said when and not if, because it will only be a matter of time till you do.

 

ok sweet!!1! I'll be right back, im going to finds out!!1

 

Theres a trick to stopping on snow/ice.
it's called enginebreaking, and yes, 4WD will help you slow down or stop faster if you engine break. Because you're not slowing your tires down, your tires are slowing your engine down and vice versa.

 

Word up to the Cooper Discoverers. i havent put studs in them, but they sure are awesome in snow

 

this is exactly why I only use 4lo, it's easier to brake using the engine/trans.

 

1. Push right (skinny) pedal to floor
2. When the speedometer needle stops moving up, you're there.

 

You can go as fast as the truck can go in 4WD HI. Your not going to hurt anything with the hubs being locked. Everything is turning in the front diff when the hubs are locked so gear oil is lubricating everything even when your in 2WD. Now you cannot SHIFT from 2WD to 4WD at a high rate of speed, that WILL possibly damage something.

Toyota, in both the Hilux and Land Cruiser, has always(or at least for a long time) used the figure of 50 mph as the 'do not exceed' speed for 4WD. It is difficult to imagine a scenario where you'd NEED or want to go much faster than that on a surface that requires 4WD, since you can't(or shouldn't) use the 4WD on smooth, dry, high-traction paved road surfaces. Sure, you could go 60mph on that dry lake bed, but if you encounter one of those 5 foot deep stream channels in the middle of your speed run, you'd be very sad(if you survived).
