Thanks again Grumpy. There's a bit of a challenge in reading that, but it gives me hope that the only thing it needs there are bushes. I reckon I'll try to get every one on that page and see how much difference it makes...it's bound to be better, and definitely no worse. If still not good enough I'll start on the tie rod ends, etc. I've shimmed the part numbered 51, which looks like it might be part of a kit ( very hard to read) and wouldn't mind getting that as well.
Are these parts available from "outdoorking" or just the belts and blades that are on the web page?
