Vibration while slowing down
My 93 F-250 w/ 7.3L N/A E4OD last night started to vibrate while slowing down. But there is no vibration when I give it a little bit of gas or foot to the floor but as soon as I let off the pedal the truck starts vibrating only when moving at any speed. No vibration when standing still idling, or reving when not moving. I want to think it could be the rear end. Any ideas before I tear the whole thing apart?

The Fluid is probably in the 60,000 mile range. but i went ahead and put the truck on the lift and one of my U-Joints was very loose. Just picked another one up and Im gonna install it and hope thats the problem

them 36" super swampers kinda would have a tendency to do that to U-joints.
keep us posted.
my thoughts jumped right to andym's reading your post too.
fyi,depending on trans temps,your about twice overdue for a trans fluid change (if using dino juice still.)

Well I've never had this problem before. I cannot get the U-joint off. I took the four bolts off the pumpkin side and took the shaft out of the transmission and I put the drive shaft into the vice and I cant get it to budge no matter how hard I hit it. Gonna break out the torch tomorrow to heat it up and try again.
Transmission.... trying to fill up 17 quarts gets a little expensive sometimes. (Just dropping the pan, ATS Deep Pan) I was told to change the transmission fluid every 80K miles. How often am I supposed to change it?
And im not running the swampers anymore, got just a little too expensive and im running on a set or tractor trailer tires.

as general rule; 15k-20k miles towing/off road/working her good,30k miles normal driving.
true,it's not cheap to flush a trans every 30k miles max,but sure is cheaper than replacing it.
Mercon or Mercon 5 only.

I got it out and replaced. I used the socket idea plus thje heat from the torch and it popped right out. New U-joint is in and the vibration is gone. Transmission fluid was changed as well.
