Whirlpool top loader, about 5 yrs old. The dog ears and maybe the cam need replacement, since just the top of the agitator is not agitating. I found a site that illustrated the process of disassembly and replacement. I have removed the fabric softener dispenser, and the center bolt and seal in the agitator. At this point, some sort of retaining clip must still be holding things together, for I am unable to separate the upper and lower parts of the agitator. Any Advice? tHANKS!
