just purchased 2000 f 150 4x4 ext.cab 8' bed long wheel base.the seller said the truck has only 60,000. miles also dose the car fax.the truck came with a class three towing hitch wich leads me to beleive some amout of towing it has seen ,how much not sure. there is i slight bit of vibration at about 70 not very much though, the truck dose have old tires and could need some new.anyhow when shifting into 4x4 it drives fine straight but when i turn the wheel in either direction it seems to get very tight,and slows the truck down.I am on dry pavment and relize that its not the right terrain to use this on but how tight should be? im kinda leerie about taking it any faster even on say dirt or grass just to test it .and my question is is this normal or is it a symtom of a problem.

 

Do not use on dry pavement!

 

In a striaght line it will not be very noticable, but i have said before, when mine is in 4 x 4 and you try to TURN, its like trying to heard elephants.

 

NEVER,NEVER,NEVER.

 

You have to have some " Slip " when in 4x4. Dry pavement is a no no! You want to test the 4x4 drive it around a big yard or field. It's better if it has varied terrain. There should be no noises. It should drive / sound just like on the street. But you can go anywhere within reason. Look at the visor in front of the driver. It should tell you how to shift into 4low. This will really tell you if the 4x4 is working. It will be 1/2 speed then normal. But you can almost climb trees it has so much 4x4 traction.

 

NEVER USE 4X4 ON PAVEMENT!

The reason it is hard to turn is because your are binding the transfer case, it will jerk and lurch and drag tires because of this. Do it hard enough and you will break or stretch the chain in your transfer case and ruin all kinds of things!!

Like above guy said, drive it around somewhere slippery, like a small amount of mud or loose dirt or sand or something. Easy way to tell, drive somewhere in 2X4, get stuck as you can, then see if you can get it out with 4X4

Might wanna have a friend handy....

 

thx for the good info ,i'll have to try that getting stuck thing i use to be good at that with my 4x2
