Does anyone know if there is anyway to tighten the front armrests? On my old Rx300 the tension was much tighter and could easiliy be adjusted to a comfortable position and it would stay there. On my RX330 the slightest pressure on the armrest pushes it down completely. Currently the armrest is useless to me. I have asked the dealer and they have told me that it cannot be adjusted. Does anyone have any thoughts.

Thanks in advance for your input.
