Issues disengaging 4H?

I understand...

I was just puzzled when people start saying that it won't go back into 2wd fast enough... So I was thinking that how the hell do I actively manage it if it with go back and forth quickly...

 

Ah, I got it. Taking your foot off the gas generally helps in both directions, and sometimes a goose of the pedal (gently) can do it too. I've always had part time in my 4x4s so it's something I've just gotten a feel for over the years.

It's also good to note that if the pavement is patches of ice/snow and dry, so long as it's not curvy you are ok to be in 4WD. A straight line in 4WD won't hurt regardless of the surface. If it's really patchy road conditions and it's a windy road, I will slow down to manage the conditions in 2WD. You should be slowing down in poor conditions anyway, because 4 wheel drive does not equate to 4 wheel stop. You still need all that extra time to slow and maintain control. So many people make the incorrect assumption that 4x4, full time or part time, means you drive like the roads are still good. That's absolute folly and you still have to drive according to conditions.

 

An auto 4wd option would be great for those that would benefit from it. Winter time here, like yesterday morning, saw pure packed snow ice roads that required 4wd (hills, stop/start) then sections that were salted and bare didn’t. No amount of sand in my bed would help taking off in an intersection in traffic at a normal speed. Grew up in the 90’s with my father only having 2wd trucks and used sand because that was all we had, no 4x4 lever to pull..
Weight helps but ultimately 4wd is far superior

 

A lot of cars in that traffic are FWD. Some are AWD, but with a crappiest tires possible. Air down to road conditions and you'll be alright in 2WD

 

The problem here is expecting "normal speed" in shit conditions. Plenty of 2WD vehicles operate just fine with proper tires in those scenarios. It just happens slower to account for the conditions.

 

I'm going to snowy parts of Maine a few times a year. Before Tundra I was driving AWD Volvo, which is actually pretty good in snow. Swedes tuned it for snow for sure. Then I switched to Tundra and almost immediately found that:

1. A-TRAC is worse than Haldex
2. but Tundra does not care much and is able to move faster and safer than Volvo

That is on a slightly plowed country road with a lot of ice patches.

 

I'm sure there are differences in systems. My WRX had amazing AWD. Best I've experienced in a car. I still slowed down for crappy conditions though. Even great tires and systems won't change the lack of traction when you need to stop or corner, so driving for the conditions is always my go to.

 

Yes, true.

First I wanted to swap transfer case to LX570/Sequoia's one. Because the truck has 4 wheels and they all should participate, right? Then I slowly grew on the fact that Tundra in 2WD has enough traction in most conditions. Then we got wife a Sequoia with full time 4HI, and I can officially sign off that 2WD in Tundra is adequate in most of winter situations.

The only issue was transfer case going in/out 4HI somewhat unreliably, but that is gone with fluid replaced to Ravenol.

 

Being alright is one thing. I can remove every option on my $65,000 truck and be alright. Simply saying auto 4wd is a great feature

 

I grew up in the shit conditions, operate just fine is what I grew up with. For the prices of these trucks, an auto 4wd setting isn’t too much to ask for. All the competition does it. And saying “go buy the competition” is a cop out.

 

You can get auto 4wd setting as an option on most domestic trucks that aren’t high end.
I had a ram new in 2012 that was $36,000 Canadian that had it.

 

Yes. 4 settings. Same 3 you and I have plus the auto 4wd setting

 

It’s very useful in northern climates where the county roads may be snow and ice then main town roads are bare. At least make it optional Toyota

 

Auto 4WD is just a convenience. Toyota didn’t add it because it didn’t meet their strength requirements. The mechanism in a auto 4WD transfer case is different from a standard one.

 

where did you get that info about the strength?

 

My past f150 had it, first time was all excited then realized it was not as great as I expected. No load your pretty much in 2wd, good for launching under heavy throttle, light throttle only engages the clutch pack once it detected wheel spin then it snaps your head back. Do not believe I'll miss it any.

 

The chief engineer said something to that effect in an interview I saw at the launch timing. He showed how beefy the transfer case chain was. Auto 4WD uses slip clutches to engage the front axle which can have weaknesses. Toyota does have similar systems for their smaller SUVs, the rear diff is engaged via a clutch so the vehicle can operate in 2WD unless slip is detected.

 

Apocolypse/doomsday/prepper scenarios come to mind.

 

I'd rather have it somewhat engaged not off or on like the Ford was.

 

AWD would be the best but honestly, I have 0 problems switching to 4H on the fly. If it’s snowy enough, I leave it on. I do usually have some problem with 4L and slow engagement/disengagement.

 

Convenience is what I’m looking for. Isn’t that what 90% of these trucks are for? I mean I have a heated steering wheel ffs!

 

I’ve never used the ford system but have the gm and ram. It always worked seem less for me.

 

Yeah the GM system is really good.

OP, just watch your turns and switch in and out. If it won’t disengage, just give it some beans, and it will go (4H flashing)

It’s fine once you get used to it. Took me 1 storm and it’s second nature.

 

Yes, right up there with no bed lights, rear power outlet and cloth seats. Toyota Canada forces you into the next trim to get certain things you want. In my case 10k. Now that’s rich
