I got all new inner and outter bearings and oil seals for the front wheel hub but I cant seem to get the old bearings out which are mangled. Theres like this lip thats preventing the bearings from exiting. Can anyone explain from experience how to do this or a certain way? Also, I replaced the sprocket as the OEM was worn out, and on the OEM there was this gasket just as big as the sprocket going around it but was cracked up. Just wondering if I need a new gasket to put the replacement sprocket on or just bolt the sprocket on?
