driveshaft

I replaced center driveshaft carrier bushing myself and after about 100 miles it has started same problem again. It vibrates when pulling boat and some without load when going up hill. I went under truck and inspected driveshaft and found center bushing again was very loose just as the one I just replaced . Any thoughts ?

 

Might have got a bad ‘new’ carrier bearing. Are your universal joints good. They can cause vibration when they start to go out

And welcome to TW!

edit I did a quick search on driveshaft vibration and a bunch of threads/info came up. On the TW Home screen there a magnifying glass toward the top right. You can enter your key words/problem in there and usually find something on it. Not always exactly what you’re looking for but a good place to start.

Truck stock or lifted? Are all the U joints in good shape. Don't assume just because they are tight they are good, you have to check for free movement thru it's range of motion with no binding. I've had plenty of ''tight'' U joints that had no slop but were seized up and causing vibration issues.

 

These are the answers.
