Sony Discman D-555 Plays great will not skip tracks

Hi All,

I have just finished recapping my D-555. Now, if I play a cd and let it run from track 1 through the end of the disc, all works great. No skips and sounds amazing, but If I try to skip a track it starts to hunt around for focus for up to a minute. It usually will catch eventually and start playing. It also seems to have an easier time going to the next track, or back one, than if I try to skip 3 tracks ahead for example. I cleaned some old grease from the sled , but not sure what to try next. Thanks for any help !!!
