[Saff]

Hi and thanks. The vibration is MUCH reduced so the renewal of the centre bearing and joint have certainly had a positive effect. The smaller joint which cannot be replaced I'm told was still described as notchy. I can live with it in the short term as long as I keep my speed down under the threshold and patiently await a new-ish replacement. If push comes to shove I'll have to bite the bullet and buy a new one from Audi.
I've been considering the used one you've flagged up but I would need to inspect it before purchase and Kent is a long way from Lancs sadly.
Thanks for your continued help and interest with this. Steve.
