Slight play in lower wishbone ball joint

[Bob L]

Servicing the car and noted very slight movement in the L/H front lower ball joint.  Can't be seen but can be felt by using a bar a raising the wheel while a finger is under the bolt.  Accompanied by a slight click (not as bad as a clonk!).  Car is a Wide track 99 1.8 K series.  What needs to be changed.  Is it just a joint or the whole L/H lower wishbone or upright as well?  Slight vertical movement only, no lateral.  R/H side has no play at all.

Thanks.

Spherical bearing and circlip in lower wishbone. Can be a swine to remove.

Part number ABWT10 for the bearing from your local bearing stockists or on line bearing supplier

This thread details the type. The bearing is generally available, circlip not so sure maybe try Redline. To remove mine I used some threaded bar and selection of washers and sockets.
