Worn out driveshaft?
I have a 1999 F-150 with 180,000 miles and recently had the u-joints replaced. Soon after I started feeling a bad vibration in the back. They told me I had lost a balance weight on my drive shaft. I took it in to have it balanced and they said that wasn't the problem at all.
The problem was that it was slightly flatened on both sides of each end from the installation of the u-joints. I was told that was a factor but also after a lot of miles driveshafts do go bad due to the rust and regular wear and tear and that factory shafts are considered "cheap" to keep costs down due to mass production. Any truth to this? Anyone ever heard of drive shafts going bad after alot of miles?
Thanks for the reply.

If i read your post right, they squeezed the tube in the vise when holding it to change the joints. Some small amount might not hurt, but if your problem started shortly after the joints were installed, i suspect it is related. I think i would take the shaft off and wobble the joints by hand to see what i could feel inside the bearing.. then look at the shaft close for damage.
