My Sport Trac developed a vibration a few months ago, at about 100,000 miles, from 45 mph on up. Felt like it's coming from the rear, but definitely a drivetrain vibration. Saw that the carrier bearing was worn out in the rear driveshaft, so replaced the whole unit with Fort Wayne Clutch's serviceable replacement driveshaft. This did not fix or change the vibration at all.
Started troubleshooting. Removed the front driveshaft, drove it only with the rear. Vibration still existed. Removed the rear driveshaft, and drove only on the front. Vibration wasn't there. So, I suspected the new rear driveshaft was out of balance.
Had the new driveshaft rebalanced by Fort Wayne Clutch. They said that it was balanced well already, but they did put a couple more small weights on it. Reinstalled the driveshaft, and the vibration is still there, but seems slightly better. Fort Wayne Clutch advises that there may be something wrong with the rear end.
Any thoughts?
