Hi, I have now found the service manual, which will be very helpful for future use, thanks. It has the part number for the prop bearing, but it appears to be discontinued.I know most parts are Mercedes SLK r170. Is the prop bearing definately the same as a SLK320 Auto. Some places I have read that Auto and manual cars have a different bearing, so confused !
