Hello ,

I have a 93 toyo 4runner 4x4 sr5 3.0L v6. Everytime i put it in 4wd and drive 20mph or so my 4wd seems to bind up in the front and it starts to get harder and harder to turn the wheel. and then when i take it out of 4wd i hear a loud popping noise and my truck feels like it has just driven off a curb.( but i didn't)

Any help?? any suggestions or a place to start looking??

 

If your driving on the road it will do that...

 

does it mean anything is broken??

 

I'll be watching this thread because my 89 pickup does the same thing only on hard right turns (backing out of parking space), hard left turns it's fine.

Bad front axle?

22RE 4X4 5-speed

 

what size tires do you have and where are you doing this?

 

Perfectly normal drive train binding in a part time 4WD system. Assuming you are doing this test on pavement or other high traction surface, you are seeing the binding due to wheels traveling different distances while turning. Good idea not to use 4WD on high traction surfaces for this very reason.

 

or maybe you have a front locker and don't know it

 

I have 31x10.50r15 bfg All terrain tires. It binds up on pavement while turning. And i think this is what caused me to have to replace a cv axle.

 

yeah, leave the T-case in 2wd on the pavment; 4wd on the pavement will just lead to broken parts and very quickly worn tires.

4wd is meant mainly of off road or low traction conditions as mentioned above, like icey roads for instance, because it allows for a bit of wheel "slippage", for lack of a better word.

These reason this happened is because there's no differential between the front and rear axle on these Yotes. The gearing trys to make them spin at the same speed, but by turning , you make the front axle travel just a bit further then the rear axle, causing the binding.

 

You're not supposed to engage into 4wd while on paved roads.

 

ok if you drive on snow then a plowed parking lot this is what you do but it in park brick the gas pedal and drop it into drive and jump out!! ha ha no dont do that

if you have locking hubs then lock em who cares right it wont hurt anything and it alows you to hit 4wd when you want ok so your in the snow or what ever and your in 4wd then when you wanna trun pop her into 2wd turn and then go back into 4wd when you want it or need it really

 

I wish! Why does mine only do it on right turns?

 

A locker in the axle (front or rear) makes no difference. It is the transfer case that is the source of the binding. Why? The front drive section is gear or chain driven and forces the front drive shaft to turn exactly the same speed as the rear shaft. Fine in a straight line, but turn and the front wheels travel a wider arc than the rear wheels. This makes the front tires make more rotations than the rear tires and this is what binds up the whole drive train until something slips and lets the tension release.

 

 

um, exactly as I staded in my previous post...

 

I knew someone, not gonna say a friend cause she really wasn't, that literally destroyed a vehicle by leaving it in 4wd constantly and driving it on paved roads. It was a Kia though so no big loss.

 

my 16 year old brother with his 2000 ford ranger got stuck in a 2 foot ditch, had to get lynched out by a chevy dualie, due to the inexperience of both drivers the ranger almost flopped on the passenger side, the dualie left and i yanked him out after instructing him to put it in 4low ... all said and done..
we get home after about 5 miles of driving and he said his truck has no power to it and its making weird noises.. i looked at the dash and it was still in 4low.!

i was like..


this kid was doing over 60 in 4low... tell me thats got to be bad
