i have a 1995 ram 1500 4x4 and when i bought it the 4x4 didnt work so i replaces the actuator on the front axle and replaced the vacuse selonide on top of the t case and replaces all the vacume lines. 4 low works but when i put it in 4 hi and turn the weels all the way the truck will roll for about 2 feet and then come to a stop like something is binding up. could it be both front u joints?

 

This is normal operation, and your 4h IS working.

you cannot make sharp turns in 4x4, the driveline will bind unless you are on a slippery surface.

NEVER USE 4X4 ON PAVED ROADS.

 

i know but normaly when u put 4 hi on and r making a turn u can feel the front tires kinda hop or slip but myne will just come to a complete stop

 

how do i test the front u joints or what am i looking for in a bad u joint

 

U-joints would be a problem even in 2wd.

What surface are you driving on?

 

Its fine in 2wd. I think its something I need some to personal look at
