Pry the c-clip out of the ends and press one end of the cross-shaft through the yoke until the bearing cup falls out the opposite side. Once the bearing cup falls out you tip the cross shaft out. You can beat it out with a hammer and a brass drift but you run the risk of cracking the yoke. Unless you have a hydraulic press, your best bet is to take it to a machine shop and have them press the new bearings in. That will be a very inexpensive job.
Universal Joints (U-Joints) can wear out.
Check your universal joints!
unbolt it at each of the universal joints
trasmition system
yes
Your drive shaft won't go out it will either bend or break.... The universal joints that hold it to the transmission will go out but that's about it
With driveshaft removed check the universal joints for play or binding.
Changing the angle of the drive shaft when lifting the vehicle's suspension puts excess stress on the universal joints, expect premature wear or breakage to occur.
2 one on each end of the drive shaft
Ball joints are in the front suspension, it is basically what the wheel assembly pivots on when you turn. Universal joints are on the ends of the drive shaft in a rear wheel drive vehicle. At the transmission and rear end. They give the drive line some flexibility. The same principal is in front wheel drive but are referred to as constant velocity joints, or CV joints.
The factory u-joints on an expedition are non greaseable.....I had to replace mine with universal greaseable u-joints.
Look on the ball joints, tie rod ends, & universal joints on the drive shaft. If you see none it has none.
