Trying to replace the rear u joint on a 200...

The U joint is glued in place if there the original. I use and blow torch to heat up the U joint's to melt the glue and use a hydraulic press to get the old u joints out. Do not use a 5 pound hammer to hammer out the U joint unless you don't mine a vibration in your drive shaft. The drive shaft are lighter now then the past and will damage to hard hammering. If there is a Auto Zone around your area, you can lone out a U joint removal tool which is cheaper then a new drive shaft. It's like a clamp, but one end has a cup shape to hold the drive shaft as the other end pushes the U joint out. Good luck and hope this helps. P.S don't burn your self. 

pull the end bearing off one side theres four sides like a cross on each end theres a cap to cover roller bearings if u can take 1 or 2 out it will give u some play there should be some kind of clips though look over once more maybe u nissed something a vise really comes in handy while replacing u joints,put in vice get a bolt butted up against the bearing cover crank the vise and should pop right out
