I had the same problem on my rrr. I actually found that all of the arms where a little tight. the lower being very tight. I used a 3mm drill bit and carefully ran it through the hing pin holes on the arms all the way through so that the bit was going through both holes at the same time.... This lined them up and they are free now without extra play. be carefull and go slow. do a little bit and then reassemble and check, do again if you need to. There was also a little binding from the flashing on the arms and I filed that off. Something to check anyway.
