when in 4x4 truck slows truck to a stop

I am looking to buy a 2005 tacoma 4x4. When I put it into 4 wheel drive it drives really stiff. in fact at speeds under 10 mph it will stop the truck as if you were pressiing on the brake. Any ideas?

 

Sounds to me like the front drive line is stiff due to neglect maybe?

 

What range of 4x4 are you selecting 4hi or 4 low ?

 

You are not turning sharply on asphalt are you? That will definitely stop you.

 

Im in four high and just barely have the wheels turned. Ive owned 4x4 s all of my life and never seen one act like this.

 

Almost sounds like different sized tires front to rear. Binding somewhere.

 

Tires are all the same and almost new

 

2 wheel drive = no slowing down? Something in the transfer case or front differential is binding, not turning in sync with transmission and rear differential somehow. Test drive in 4 wheel drive with no front drive shaft, no binding, front differential problems.
