I have a '06 5.0 GXi with SX 280 outdrive. I think the gimbal bearing is bad and needs help. I have almost 700 hrs on the motor & outdrive. I have a vibration and sluggish start at low end. It all seeems to go away once moving straight again. I pumped grease into the one zerk I have on the outside of the transom, this made no noteable change. I now feel I need to remove the outdrive and see what is going on. Any ideas on removal or should I leave it for the shop. I have not removed it before but am pretty mechanially inclined.
