Thanks for the advice everyone. I can now make it clunk by shaking the steering around the centre point. I think the main cause is cleaning off the grease and replacing it with a much softer grease. I have already checked that everything is tight.
I didn’t know this but grease has a thickness rating 1-6. 1 is semi fluid and 6 come as a brick like fudge. I have ordered some 3 and 4 in case the proper grease is not thick enough to cushion it after adjusting. I expect I have most of the wear on centre and so adjusting will be between two conflicting compromises of binding off centre and backlash on centre. The grease rating is called NLGI. Sometimes the name of the product will have this rating number e.g. EP2 or NG3.
The racks are £200-400 remanufactured which is not bad but the task of fitting looks terrible.
Maybe this greasing should be a maintenance item say every 100,000 miles to help reduce wear.
