Good morning, yes, the frame weight it still hanging there. As I have zero experience with replacing u-joints myself, is there a way to visually inspect that they have been installed correctly? The vibration is not a gradually increasing "shake", but a something that reminds me of a rotor or centrifuge that is out of balance. The faster it spins, the more vibration it transfers to the vehicle, and it increased when I let off the gas, and is slightly less under acceleration. I will mess with is after tomorrow. Happy Thanksgiving and thanks for your insight!
