Hi Have just bought a new genuine L/R rear windscreen wiper arm for my 2006 RRS, taken the old one off and refitted the new one.....simples? NO!! I get it to line up with the squiggly heater elements on the rear screen, but then after it's done a wipe it comes back about 2- 3 inches above the suiggly lines.

Now I can place it so it's either 2-3 inceh above the squiggly line or the below the lines but cant get it to stop on the bloody squiggly lines after it's come over and back! Please help with any suggestions as there seems to be a bit of play with the arm, feels like the nut is not tight enough, yet it is.....Your thoughts please - motor bearing?
