Glad to hear that you are sorted.
Best not to let your car tick over from cold as it will petrol wash the bores.
Any warming up should be done when on the move.

A compression rod ball joint knock is completely different from a compression rod bushing knock.
It after an informed inspection no fault is obvious then it will be the compression rod ball joint that is giving the knock.

The later racks are different from the early cars, however the 2006 should be compatible with the 2003.
2003 - 2005 preowned racks are in stock if required and all guaranteed to be servicable and with no leaks
Just drop me a PM if I can help further.
