Re: Clanking sound from rear of truck
All you need to do to check the pinion nut is to remove the drive shaft from the rear yoke. It's very common for the pinion nut to back off, but don't tighten it any more than what you are able to do with a common 1/2 inch drive ratchet. Be sure that the truck can not move when you do this. Nobody wants you to get crushed by your truck.
If you feel any loose movement in any of the U joints it's too much.
