4 wheel driv problem

Today I was testing out my 4 wheel driv system and noticed when engaged and turning (fairly sharp) one of my wheels was locking up(not sure which one). Any suggestions before bringing it into toyota dealer(still under power train warranty).

 

No not a problem. Completely normal. Dont switch into 4wd on pavement

 

If its still under warranty i wouldnt even worry about the problem, Go in tell them the problem and let them wrench away at it. If i had to guess id say maybe a bearing... I havent really gotten into the 4x4 system in our trucks alot. But It sounds like it could even be a link of some sort. GL with the fix man.

 

Have you noticed that problem in your truck?

 

Its completely normal. DON'T DRIVE IN 4WD ON PAVEMENT! It puts stress on your drivetrain and you could snap your chain. Read your owners manual.

 

Thanks

 

It's not a problem , you aren't supposed to use 4x4 on a surface with no give . It's normal for the wheels to bind up .

 

I think the problem is misunderstanding of how 4wd works - people think it's the same as the all wheel drive systems from subaru and other makers.

I was explaining to someone a week ago how I cant do 4wd on pavement with the tacoma and they were skeptical: "Oh that sounds sketchy... sounds like an outdated or poorly made system!"

Someone more articulate than me came along and explained how it works.

I assume all this information is in the manual? When I get my truck I intend to read it cover-to-cover

 

Our trucks have part time 4WD. Try to get in the habit of not making ANY sharp turns while it's engaged. The tires need some slippage...never use 4WD on dry pavement. Even while offroad try to do wide turns...never full lock. When in a parking situations even on snow I get back into 2WD. Read the links below for more information...

 

Awd is different than 4wd. 4wd vehiclas have the central diff locked at all times unlike a awd which has an open central diff

 

Don't count on it...the owners manual is lacking alot information on this subject.

 

No... but you are on the right track... Tacoma 4WDs (and other Part Time 4WDs) do NOT have any 'central diff'... they have only the transfer case in the middle that puts equal power to the front and the rear differentials in 4WD. Because the front and rear drive shafts will rotate differently when turning, Part Time 4WDs should only be used on slippery surfaces (low traction) so the tires can slip as needed when turning.

AWD (Full Time 4WD) vehicle have a center differential and that allows the front and rear drive shafts to rotate differently for dry pavement use. The issue with AWD on off road vehicles is the power split is not equal between the front and back, as it may need to be.

Off Road vehicles that have AWD will have a center differential lockout... thus eliminating it and making the vehicle 'part time' for serious off roading that requires the 50-50 power split.

 

Who are you, my mother?

The only thing you need to fear are the truth and facts of 4WD

 

hahaha..

reminds me of a snow trip i did a few years ago with BrandonH, dtrujillo63, SiRMarlon, and J4RR. i forgot to go back into 2H and drove home roughly 35 miles on the freeway in 4H averaging 75+ MPH like normal. didnt notice until i was turning into a parking spot at a Starbucks..i was like WTH is that binding as i was turning into my spot

 

My owners manual say nothing about driving in 4wd on pavement or loose surface. Everyone in the forum has pretty much concluded, not to drive on pavement. How about wet pavement, would that be enough tire slippage?

 

The derp is strong within this thread...

 

Why would you want to engage 4wd on wet pavement? Save it for mud or snow.





Gave my 4wd system a good work on friday.

 

Well at least test it out on loose gravel or dirt.

 

If you think you need to engage 4WD on wet pavement your either driving too fast or you need new tires. The only time you should need it on pavement is when snow or ice is a factor.

 

Great sites for learning about 4w drive facts!
