large vibration while accelerating
I just corrected another misfire issue with plugs/wires/coil/CKPS, within about 15 miles of a test drive I noticed a large vibration and noise during acceleration or maintaining speed going uphill or up slight incline. While coasting or using little throttle the vibration does not occur. It starts around 1600RPM and continues until I let off the gas. The vibration does not occur while in park or neutral.
I'm lost before I even started trying to figure this out, where do I start since I must have the vehicle running at 15mph+ before the symptoms start?

If your Front Drive-shaft (Prop-shaft) has never been rebuilt, do that before you drive it again. You can tell it has been rebuit if it has a grease fitting on each of the U-joints (3). If only the front U-joint has a grease fitting that is original.
Take a look at your Flex-joint at the rear of your Rear Drive-shaft. If it is less than perfect, has any small cracks at all, then replace it. If it has never been replaced at 126K then it is due. In fact, replace it anyway. If the vibration persists then keep the old part as a spare.

If there's one thing you really need to do, it is check your front driveshaft to see if it has been rebuilt. When (not if) the original driveshaft fails, it swings into your transmission and tears it apart (damage is directly proportional to your speed). You'd be looking at a new driveshaft, new transmission, and loads of time troubleshooting whatever damage might also have been caused.
You can buy a Tom Woods for $400, rebuilt ones for less than that, or rebuild it yourself for <$200.
It's not a matter of if/crossing fingers, but when. You really don't want to risk this one.
