Hi, One of my rear bearings on my 8P Audi A3 (2004) sounds like it needs changing now. Can anyone help with a few questions i have? I've had a search and read some posts on this and I understand these come as a sealed unit... http://www.eurocarparts.com/ecp/c/Au...8698a870e&WBRK Does this mean its a much simpler task to replace with no need to add grease, remove races etc? Do i need any special tools like a puller, press etc? Also is there a suitable VAG variant that has a Haynes manual that will cover this (nothing for the 8P A3 yet ) I've found a few how-to's online but these are for bearings that can be refurbished and I'd like a decent set of instructions before starting. Any help would be useful and appreciated... Thanks!
