Morning, Just wondering if anyone has replaced one of these before? My center bearing collapsed this weekend, causing all kinds of rattling noises - the prop now has play in it. Will this replacement bearing do the job?: AUDI A4 QUATTRO PROPSHAFT CENTER SUPPORT BEARING NEW 30MM | eBay Also, does anyone know if the quattro can be run as 2wd if the propshaft is removed? or will this cause damage? Thanks.
