C20 vibrations - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My c20 is the first 3/4 ton truck that I have owned. It's got the factory heavy duty option, so I am not expecting it to ride like a modern truck or SUV.

I am starting to notice a vibration between 45~55mph (bed is unloaded). It actual gets kind of bouncy. The steering feels fine at any speed.

I am going to check out the ujoints, when I get around to it. The shocks look warn out, so I am probably going to have to replace them in the near future.

Does anyone else have a bouncy C20 or C30?
