There is a web site "Simply Bearings" where you can insert the sizes. Your code did not work. Decades ago my father and I used to take rusty old ball races along to the bearing supplier, they'd get measured up and a choice of FAG, Timken or SKF offered.

Ok thanks for the help people, finally got this sorted and the car is back on the road no prob. Simplybearings where no help at all.

The final solution came from BRT Bearings in Lincoln who did the number crunching and came up with bearing kit pack number PWK0745.

The bearing in this pack was ment for a TOYOTA PREVIA but I've been told it is also compatable with the 2.3L diesel Mazda 6 as well. It is the correct size, the only difference is that the new bearing part number is DAC4584w-1 and the old one was DAC4584w-5 not sure of the difference (and I don't mean 4); if you know then give us a shout.

The price was a resonable 41.64 plus vat only a fiver more than the first incorrect one I got from Mazda so happy with that.

A part from the faff with finding the new bearing the job was quiet easy in the end and with some simple tools and a press I got it done in aroun 3hrs. One tip you need large diameter ball joint spliters, my standard ones wheren't up to the job and I had to resort to using a second jack and a big hammer to split the bottom pair.

Hope this string helps and any 2007 Mazda 6 drivers out there with creaping millage beware your motor might just have some None standard parts fitted to
