Vibration Problems!!!!!!!!!!!

Have A 95 F350 SRW 351W AOD trans. I am getting a wild vibration at 45 to 65 mph. Guy at the parts store recommended a tranny service, its been 32K since it was serviced so I went with it. It did slightly smooth the vibes out some but didn't eliminate them. I was thinking U-joint (rear), doesn't have a carrier bearing, but when you put the truck into gear everything is smooth. Any ides??

No, the speedo is fine. I had the tires balanced today, no help. The vibe stops when you let off the gas or put it in neutral at any speed you feel it vibrating.

sound like a u joint. if you get under the truck and force the u joints back and forth you might be able to see if they are worn.

This all started about 2 months ago with some sort of squeak from the underside of the truck. It sounded like the drive shaft was rubbing a heat shield when you accelerated. I looked but found no metal contact. Has original U-Joints so couldn't grease them. I sprayed WD40 around the joints and after about 30 miles it decreased the squeak, then the vibrations became worse. I can get it to ocassionally make the clunk sound when going into reverse, but can't really say I see movement when I move it back and forth.

you just sealed the deal. You have a U-Joint that's worn out. That should be a $20 fix, $40 tops if someone else does it.

The rear U-joint solved the problem. It still looked really good on the outside, but after pulling one of the caps, WOW!!. One end was just dust. I guess that was the initial squeak. Anyway all is well, thanks for the feed back guys!!
