The best way to check the U-joints for binding is simply to remove the driveshaft and feel how easily they can be rotated in both directions by hand. Don't forget that a dented driveshaft or a weight knocked off balance can create the same vibrations as a binding U-joint.
While in four-wheel drive, binding of the drive train is caused by: Select one: a. loose binding straps on the transfer case. b. the fact that the front wheels travel farther than the rear wheels. c. the fact that the rear wheels travel farther than the front wheels. d. incorrect drive shaft spacing. The driveshaft angle on a vehicle with stock suspension and height will probably not be a problem. However, suspension modifications could cause you problems. When checking the angle, make sure the vehicle’s wheels are on the ground or on a drive-on hoist. Check the angle with proper angle measuring tools. i have a 1996 jeep grand cherokee larado and had the same problems with turning, mine has 230 thousand miles on it, skipping when turning sharp , feeling like its binding up . I HAD MY FRONT DIFF REBUILT WITH A NEW PINION GEAR AND PROBLEM SOLVED TURNS NICE NOW, ITS NOT JUST A JEEP THING, DONT LET ANYONE TELL U THAT. 1.) At low speed sharp turns you can feel the front wheels binding, without throttle it comes to a complete stop in drive and if you apply any throttle it almost feels like your going over a speed bump. "crow hop"? I unplugged the electrical connector to the encoder motor and that changed nothing. I've noticed that the last few times I've driven it, it feels like the AWD is binding when I do a low speed sharp turn. Also, I lifted it in my garage this morning to check out changing the fluids myself (decided against it), and while I had all 4 wheels off the ground and found that there is a lot of "slop" in the front axle... Allow me to ...
The slowing effect caused by front wheels stresses all components between wheels and the transfer case. It causes mechanical components to bind instead of moving freely - this situation is called "axle binding" ,"driveline binding" or "driveline wind up".
While in four-wheel drive, binding of the drive train is caused by: the fact that the front wheels travel farther than the rear wheels. Technician A says that driveline binding can be caused by tires that have different circumferences. Rear differential binding? I began noticing increased friction in the drivetrain, along with overheating problems. Upon further inspection I isolated the friction to the rear drivetrain.
