Belt tensioner replacement.

Today after listening to my dads 97k2500 I noticed that the motor seemed a lot quieter then my k1500. so I decided to investigate and discovered that the idler pulley and tension pulley were the culprits. So I went to napa and bought a new idler pulley and they had to order the tensioner pulley ( it will be here tomorrow). I put the new idler on and it's a lot quieter and smoother. However after I did that I noticed that my tensioner pulley jumps now just a little and not all the time( I'm not sure if it did that before or not). The part I have ordered is just the pulley part, I have done a lot of reading about it and I read that it is normal and I have also read it shouldn't move at all so I'm kinda confused about it what do you guys think?

 

Ps when I rev the motor the tensioner moves more, which to me seems like it would be normal to make the belt tighter.

I decided to spend a little extra and just replace the whole tensioner. The new one doesn't bounce at all. I just need to replace the belt now.
