Turns out there is a wheel bearing retainer, so I order the special tool and find out it's 47mm and my retainer is around 43-44mm. So I heat up the retainer and get a punch and hammer out. retainer is FUBAR'd now, but out.
Is this retainer absolutely necessary? I ordered another one just in case. Also, is 2004 the odd year for these retainers (44mm as opposed to 47mm) or do I possibly have a rear wheel from another bike?
Thanks for the help in advance
