Hey all

Recently, my 2000 GTS has developed a steering lean to the right. I had no idea where the problem was developing, except that the rear right suspension would sometimes make noise. On closer examination today, I found that the rear right lower suspension control arm has developed quite the crack:

I think this part # is 48710A.

Is this correct part? If so, must the part be replaced? Can this be fixed?

If it cant be fixed, does anyone have any leads on a cheap replacement?

Thanks for your help!
