4WD issue? 6MT

So, haven't really used my 4WD since I've had the new 18 Sport 6MT, and had a chance to just use it as we're getting snow here in Maine. Well, in my 17 Sport, it was flawless and drove fine. In my 18, it was going good, until I got into a parking lot, and when I went to turn down a lane (sharper right turn) it was like I slammed on my brakes. Truck came to a stop quickly and I stalled. Restarted truck, attempted to continue the turn, and it nearly stalled again. Turned off 4WD, and continued on around the parking lot from there without an issue. Turned back on, and it started doing it again. I've never had this happen in the 20 years I've been driving Manual 4x4s.

Could the 4WD system just be tight due to never using it? Or should I be taking this to Toyota to have them take a peak at it? I'm completely boggled.

 

You’re binding the 4WD system because it’s not slippery enough. Go into 2wd for tight parking turns like that or use more gas/clutch to prevent the stall.

Hmm, roads are completely snow/ice covered, but you might be right. I wasn't looking closely to see if salted, and honestly, I almost never use 4WD in any vehicle when in a Parking lot. It's usually only a off roading or when I get stuck kind of thing.

I'll get it home and into some deep snow in the back yard and give it another shot and see if that makes a difference. Thanks.

 

Correct. The more bind you get on the front,especially with asphalt below,the more likely it will feel like the brakes are on. Your literally driving over a tire that you're also asking to turn. It's physics. Sure some of the other tacos may have needed less gas, felt less or more torque,but those are all angles and mainly road/surface conditions. Currently I wouldn't be concerned. Further,even if the surface is slick,it can still feel similar,you're still pushing"over" a turning tire. Did a slow tightturn in a muddy rut the other day. So, don't be alarmed. Just try not to turn tight. And if you have to, just limit it and ONLY do it where the surface isntdry pavement .

 

Yea, most likely what's happened. Just never, in 20 years of driving Tacomas, had it happen to me, so threw me off. Guessing the lack of low end torque is shining through. :shrug:

 

Yeah, on my first gen it wasn't as pronounced. However, while it may seem counterintuitive in one way,you can put it in 4lo, you'll find the torque is more readily available. Again, not on dry pavement, but with a slippery surface and a turn you may see it's just the torque at higher rpm. Just a simple test prove nothing is wrong and discover it's the torque band .

 

What are the chances the safety sense was triggered by turning towards the parked cars?

 

I'd say extremely unlikely... most likely ZERO chance. I've felt what he's describing in every 4WD.

 

I’ve felt 4WD binding lots, just not in a way where it would suddenly stall a Truck.

 

Which is odd, as I've never felt it, unless turning on dry pavement (and it's snow and ice covered here currently)

 

You've never binded the 4wd in 20 years and make a joke about low end torque? You need to get out more.

 

Well you drive an automatic so that would make sense then.

 

Duh....like this is the only truck I’ve ever owned that my mom bought me.

 

what tires do are you running? I have Blizzaks on right now and they've got such incredible grip in the snow that I haven't been putting it in 4x4......if I do in tight parking lots, I bind as if it were in 4x4 on dry pavement.

 

You should never be in 4hi in a parking lot unless its a sheet of ice...you're binding the drive train

 

Or a lot of snow and non-snow tires.....

 

Oh I dunno, big empty parking lot with 10 inches of snow is 4wd drifting glory...I suggest more loud pedal

 

Ha! Well, we've all been there! But I think OP was making sharp turns with his...

 

Likely was his first mistake. One should always steer with the rear in those conditions
