Narrative:

The inbound captain on his way off of the aircraft told me that he had a slight nosewheel shimmy on takeoff, but didn't notice the shimmy on landing. He asked me to look at the nosewheels. I did look at the nosewheels and they looked new with no flat spots. I also looked at the grease fittings and they looked like they had just recently been lubed. I reported all of this to the outbound captain and he said he would let us know what he found. I next heard from the line controller that the captain had written up a severe nose shimmy in st louis and that the trip had to cancel. I looked up the aircraft work on aug/xx/96 and found that the nose tires were changed and the aircraft put back in service.
