2000 Rear wiper replacement
 

I just bought a 2000 4runner and I'm in the process of replacing some of the worn out things that came with it when I bought it. I tried replacing the rear wiper but found that I coudn't get the wiper off. After looking online it apears as though I may only be able to replace the wiper blades. Does anyone have any info on whether or not this is true? If I can replace the wiper, how the hell do I get that thing off? From looking at it, it looks like I'll have to replace the entire rear wiper arm :confused:
Thanks in advance for the help :)
