    XTR 952 rear derailleur slack issues

    I'm putting together my old bike and it has a XTR 952 rear der. I remember on drops and downhills the chain would go slack and I would look down and even hear the chain making a zipper noise to tighten back up. I am wondering if I need to replace the axle spring around the bolt? I'm just wondering before I go and spend the $. Thanks! I did search for a while, but most everyone just gets a new Der.

    I decided to take it apart; and it turns out the spring tension was on the lesser tensioned hole. I cleaned and re-greased and put the spring in the higher tension spot. I think that will do the trick! I will report back if it doesn't.
