Yes there is. Check your owners manual for the 50 hour periodic service and it shows the grease points for the motion control bushing and the Motion Control Contact Plate. If I remember correctly, you just use a multipurpose grease on those points and it should free up the tight control arm.
On the contact plate, I like to clean them up good before applying the grease. Sometimes the old grease on there will be hard and it makes it hard to move the control arms forward and back.
