Exclamation BAD vibration after raising ride height

In august I had a 2.5" leveling kit installed on the front of my 2wd f-250 and I didnt like how it still looked like a low rider compared to my brothers 4wd f-350. Today I installed an add-a-leaf kit (2.5") in the rear leaf springs and it looks great now but I have a serious vibration when accelerating up to about 20 mph. Is this a problem with the drive shaft length? Can I put shims under the carrier bearing to help out with what I am assuming is my drive shaft being too short? ( I saw this in a different thread but I couldn't remember what the reason it was done for.)

any input is appreciated guys, thanks!

Yes, you need to shim down the carrier bearing.

Thanks bud. I'm planning on just fabbing my own shim since I don't plan on lifting my truck any higher and I have the spare metal/time to do it. From what I've read, I think I'll need about 1/2" or 3/4" of a shim and I'm just going to use some spare 1/4" pieces I have laying around. hopefully this take care of the problem.

Forgot to ask.. Can I do this with the drive shaft still in place and just unbolt the carrier bearing?

It's as easy as it sounds... Unbolt the carrier bearing, insert shims, and bolt it up. It helps to have a friend to hold the driveshaft, but a jack and a block of wood would probably work too.
