I have a 1997 GMC sonoma, and if you take your hand, and push/pull on the drive shaft sideways, it moves probably 16th of an inch. Is this normal or doe sit mean that my middle bearing is bad (2 part drive shaft).
Is this a good question?

@parzival some movement is definitely expected and 1/16th of an inch seems to be within those tolerances. Make sure that you do not get a vibration sound (thumping) while driving which would be a more common for that bearing.

That's what i thought too! Although I can't realy tell as of right now. I have bad shocks in the back and I have no way of telling if the noise I hear is the shocks bouncing or the drive shaft vibrating. Ill replace them soon, and then I can tell.
@parzival You determine a worn out bearing really quick. It is sort off like your driveshaft knocking on the floor board asking for permission to come inside the vehicle. Very distinct sound:-) Good luck with your shocks and do us a favor. Get your camera out and create a guide when you replace those shocks. Use this guide https://www.ifixit.com/Guide/new for that. I myself am going to have to change the shocks on my F-150 this weekend and will do the same. That way ifixit repair guides for everybody keeps on growing
Ya man will do! And ya, then its just the back shocks. I know the knock your talking about and thats not it. Its just a slight vibration at the rear and when it rains, it gets so horrendous that the truck will not do over 50.
