Generally an old screwdriver and a hammer will help persuade the clips
out of the yoke. This part really doesn't require that much finnese, the
clips are included with the new joints.

This is generally the explanation given for joint removal but its very
frustrating and will give you fits. I stripped the leadscrew on my
Starret vise using this techinque. Over the years the best techinques I
have found are the following.

        1) Don't use a vise to remove the u-joints unless your resting both
edges of the
        yoke on the jaw surface. Tap with a hammer on the other yoke that is
facing you.
        The cup facing you will pop out of the yoke. Rotate the yoke 180
degree's and 
        repeat the process. that will allow you to remove one of the crosses of
this 
        single cardan joint out of the yoke. Repeat the process on the
remaining cups by 
        resting the cross (less cups) on the vise jaws. Again tap on the side
of the yoke
        to pop the cap off facing you. Repeat and finalize the removal by
rotating again
        180 degrees. 

        Clean out the yokes and debur. Gently press in the cups using the vise
jaw faces.
        Now you can get out your sockets and send them home (below the groved
surface) and
        set the circlip.

        2) OTC sells an excellent combination ball joint and u-joint press for
just over
        100 dollars. The nice thing about this tool is that it has all adapters
for ball
        joints and you can do some u-joints right on the car (not on triumph)
if their is
        enough access like on a four wheel drive.

        3) Find someone with a press and the right adapters or sacrifice your
craftsman
        sockets.

Number 1 may sound a bit strange but this is the process of choice by
professional mechanics when they don't have a u-joint press or a
hydraulic press. 

I learned this technique while working as a line mechanic (for
commision) at a new car dealer in my younger days. It works quite well
and by no means relates to beating the snot out of the yoke with a
hammer. If you enlist a B.F.H. you will inflict damage. The technique is
quite simple once learned and youl will never go back to pushing them
out with a vise.                        Support

                                           ^
                                                        Both parts of the yokes

Strike on the small x with a suitable dead blow, brass or medium weight
ball pien hammer.

Best of luck and if you use technique 1 you won't break a sweat or you
tools. email me if you still are having problems.
