Q: After I replaced my center bearing, a knocking sound from under the truck had occurred, and it has been slowly getting worse.
I've noticed this pronounced knocking sound after I replaced my center bearing not long ago. The knocking happens when I drive over bumps and while in a turn. I've tried shaking, moving, and pushing any thing under the truck including the drive shaft to reproduce the sound with no luck. When I replaced the bearing, I lifted the truck up by the frame. So I thought maybe it was the suspension. I tried jumping on the truck but still with out the sound.
