So I started getting a vibration from the rear that starts at around 40, you can hear it and feel it. It sounds like a low howl or a whirl and is felt as a rapid vibration that increases with rpms. When coming to stop at around 30 the vibration gets low and rattles the back end and the vibration can be felt moving through the drive shaft seems like it starts forward somewhat and ends at the rear.
I though it might have been the rear suspension components out of geometry because the bushings and shocks were bad. I just replaced the torque rods and pan-hard bar with IPD's adjustable ones and I put in new shocks, springs and trailing arms. That didnt fix it. Before doing those only the vibration on deceleration would occur; now, after doing the fix I have gotten the howl or whirl I first mentioned.
My first thought is maybe my rear gears are starting to disagree with each other which I hope isnt the case. Whats recommended if it is, change out the whole rear or just the center section?
I then thought could it be the drive line bushing and bearing? I hope it is because that seems like a lot less work to replace haha.
Hope you guys have some input, thanks!
