U-Joints Wearing out quickly
Hello,
I have a 1978 f150 that about every month I have to replace the U-Joints in the Rear Drive shaft (Truck is 2WD)
could it be wearing quickly because I used to put 1000 pounds of tools in the bed daily?

IMO, it shouldn't wear out that fast.
Have you checked the driveline angles? Are you careful not to overtighten the U-straps as to distort the needle bearing cups? Proper lubrication? Have you tried a different brand of U-joint? Perhaps use a genuine Spicer joint?

You are lubing them after installation correct?
The grease that comes in them isn't enough to run them, they need to be greased after they're in.
A 1000 pounds in the bed shouldn't make them wear that fast.

I had that problem on my Bronco driveshaft. Then I started paying attention that the U j-oint cap press fit in with extreme ease on one side of the double-cardan joint. It was the one that continued to fail. Swapped it out with another double-cardan joint and never had issues again. The tolerance was out ever so slightly.
